Abstract:

Résumé Techniques de reproduction et reproduction de la société japonaise Les nouvelles techniques de reproduction permettent de réaliser les désirs de procréation, là où c'était auparavant impossible. Ce texte décrit comment des femmes de Tokyo en âge de se reproduire réagissent envers l'accessibilité de la fertilisation in vitro et les tests génétiques. Ces réactions et l'analyse de leur contexte d'énonciation (notamment les notions de relations de genre au Japon) démontrent que l'interprétation de la praxis du corps en ce qui concerne ces techniques doit être mise en contexte, si bien que tout débat abstrait sur l'éthique de l'utilisation des techniques de reproduction est insuffisant. Les réactions de ces femmes sont contradictoires et révèlent, d'une part, une tension entre la rhétorique japonaise courante qui est en faveur d'un accroissement de l'individualisme et, d'autre part, les obligations envers la famille immédiate. Les techniques de reproduction sont utilisées avant tout pour créer un « contrôle des naissances » grâce auquel le rejeton « conviendra » aux attentes de la vie « normale » dans la société japonaise.

Abstract:

La reproduction humaine est au coeur des rapports sociaux de sexe. Des luttes féministes ont permis aux femmes d’acquérir une plus grande autonomie reproductive certes, mais cela est devenu possible grâce à un recours à la technique. Or, la récente évolution des techniques dans le domaine de la reproduction se caractérise par la croissance d’un pouvoir externe et par une atteinte au caractère global de l’expérience des femmes. Cette évolution s’appuie sur une dévalorisation du potentiel reproducteur féminin et crée une illusion d’émancipation. L’article soulève des questions sur les valeurs qui la sous-tendent et son impact sur les rapports sociaux de sexe.

Abstract:

Dans cet entretien, Sarah Franklin revient sur son itinéraire, proposant des pistes pour aborder les transformations intervenues dans le champ de la reproduction médicalement assistée depuis 40 ans. Avec des enquêtes sur la médecine régénérative, le clonage ou les marchés de tissus et services reproductifs, Sarah Franklin est une figure incontournable de l’analyse des mutations médicales et sociales contemporaines dans le champ de la reproduction et de la parenté. Elle situe son parcours dans le sillage des pionnières de la critique féministe de l’anthropologie culturelle, des techniques et des sciences : Marylin Strathern, Shulamith Firestone ou Donna Haraway. Elle pointe les enjeux politiques et scientifiques de l’usage des technologies de la reproduction et les transformations intervenues dans la définition de la parenté. Soulignant l’importance des droits conquis par les personnes LGBTQ+, elle interroge les limites de ces transformations mobilisant la question de la « justice reproductive ».

Abstract:

This paper reviews current equine assisted reproduction techniques. Embryo transfer is the most common equine ART, but is still limited by the inability to superovulate mares effectively. Immature oocytes may be recovered by transvaginal ultrasound-guided aspiration of immature follicles, or from ovaries postmortem, and can be effectively matured in vitro. Notably, the in vivo-matured oocyte may be easily recovered from the stimulated preovulatory follicle. Standard IVF is still not repeatable in the horse; however, embryos and foals can be produced by surgical transfer of mature oocytes to the oviducts of inseminated recipient mares or via intracytoplasmic sperm injection (ICSI). Currently, ICSI and in vitro embryo culture are routinely performed by only a few laboratories, but reported blastocyst development rates approach those found after bovine IVF (i.e. 25%–35%). Nuclear transfer can be relatively efficient (up to 26% live foal rate per transferred embryo), but few laboratories are working in this area. Equine blastocysts may be biopsied via micromanipulation, with normal pregnancy rates after biopsy, and accurate genetic analysis. Equine expanded blastocysts may be vitrified after collapsing them via micromanipulation, with normal pregnancy rates after warming and transfer. Many of these recently developed techniques are now in clinical use.

Full text

Abstract:

Assessment and enhancement of joint position sense is an inexact science at best. Anew method of evaluating and improving this sense using motion-tracking technology that incorporates computer visualization graphics was examined. Injured and healthy subjects were evaluated for their abilities to determine shoulder joint position, after abduction, in two tasks. The first was active reproduction of a passively placed angle. The second was visual reproduction of such an angle. A training protocol was added to determine the effectiveness of proprioceptive training in conjunction with 3-D visualization techniques. The primary findings were (a) a significant difference (p= .05) in the level of joint position sense in injured vs. healthy subjects; (b) significantly less accurate reproduction of larger shoulder abduction vs. the smaller movement in the active reproduction task; (c) significantly greater ability to accurately reproduce angles actively vs. visually; and (d) that proprioception training using 3-D visualization techniques significantly increased activeandvisual reproductions of passively placed angles.

Abstract:

During the past decade, few fields in medicine have changed as dramatically as reproductive medicine and the treatment of male infertility. Whereas previously only men with obstructive azoospermia were candidates for treatment, either through surgical reconstruction or sperm aspiration, now even men with nonobstructive azoospermia are able to achieve pregnancies without having to resort to donor sperm. The extraordinary success of assisted reproduction after sperm retrieval for azoospermic men is the result of three important discoveries. First is the clinical observation that epididymal transit of sperm is not required for successful fertilization. Second is the recognition that significant heterogeneity in testicular biopsy specimens exists. Lastly is the advent of intracytoplasmic sperm injection (ICSI), which has enabled fertilization regardless of the degree of sperm impairment or retrieval source as long as sperm are viable. These three discoveries have enabled fertilizations and pregnancies for men previously referred for donor insemination or adoption, and have therefore broadened the indications for sperm retrieval. This review is intended to describe in detail the available techniques for the recovery of sperm, with emphasis on the latest technique, testicular microdissection for sperm retrieval in nonobstructive azoospermia.

Abstract:

The goose is a popular poultry species, and in the past two decades the goose industry has become highly profitable across the globe. Ganders low reproductive performance remains a barrier to achieving high fertility and hatchability in subsequent flocks. To address the global demand for cheaper animal protein, various methodologies for improving avian (re)production should be explored. A large amount of literature is available on reproduction traits and techniques for commercial chicken breeder flocks, while research on improved reproduction in ganders has been carried out to a lesser extent. The present review aims to provide a comprehensive literature overview focusing on recent advancements/techniques used in improving gander reproductive efficacy in the context of ensuring a globally sustainable goose industry.

Abstract:

Background: Infertility affects about 80 million individuals worldwide and 10–15% of couples at reproductive age will seek medical assistance. There is increasing evidence that pregnancies after Assisted Reproduction Techniques (ART) are associated with pre-term birth, low birthweight, congenital defects, and increased mortality rates. The aim of this review is to assess all the published literature and provide an updated review on the effect of assisted conception and perinatal and neonatal outcomes. Methods: Comprehensive research on Pubmed/Medline, Scopus, and Google scholar electronic databases was conducted from July 2023 up to September 2023, using the terms assisted reproductive techniques, ART, in vitro fertilization, IVF, intracytoplasmic sperm injection, ICSI, preterm birth, PTB, low birth weight, LBW, chromosomal defects, congenital defects, and hypospadias. In total, 87 full text articles were retrieved and after a careful evaluation, 31 studies were selected for data extraction. Results: Our review demonstrated a higher risk of congenital and chromosomal defects, and a higher incidence of male genital tract defects and heart defects in ART pregnancies. Regarding pre-term birth, our results were contradictory. Conclusions: Although assisted reproduction techniques are associated with increased risks, they are safe regarding perinatal outcomes and couples should not be discouraged from utilizing them. Our results aim to alert clinicians to these specific outcomes and offer more personalized care and counseling to infertile couples and their children.

Abstract:

Male infertility accounts for approximately 40% of infertility cases. There are many causes of male infertility, including environmental factors, age, lifestyle, infections, varicocele, and cancerous pathologies. Severe oligozoospermia, cryptozoospermia, and azoospermia (obstructive and non-obstructive) are identified as severe male factor infertility, once considered conditions of sterility. Today, in vitro fertilization (IVF) techniques are the only treatment strategy in cases of male factor infertility for which new methodologies have been developed in the manipulation of spermatozoa to achieve fertilization and increase success rates. This review is an update of in vitro manipulation techniques, in particular sperm selection, emphasizing clinical case-specific methodology. The success of an IVF process is related to infertility diagnosis, appropriate choice of treatment, and effective sperm preparation and selection. In fact, selecting the best spermatozoa to guarantee an optimal paternal heritage means increasing the blastulation, implantation, ongoing pregnancy and live birth rates, resulting in the greater success of IVF techniques.

Abstract:

The requirements of dog owners regarding assisted reproduction have been gradually increasing over the last period of time. Artificial insemination in dog has become a common demand in veterinary clinics nowadays. The practitioner’s knowledge of the canine reproductive physiology and pathology associated with the skills required to perform specific procedures are essential to ensure success and to avoid problems in the use of artificial insemination in dogs. The aim of this paper is to revise the current knowledge about the techniques used in artificial insemination and some problems associated to these techniques.

Abstract:

The reproductive physiology of canids is unique compared to other mammalian species. Specifically, the reproductive cycle of female canids is characterized by extended periods of proestrus and estrus followed by obligatory diestrus and protracted ovarian inactivity (anestrus). Although canid reproduction follows this general pattern, studies have shown variations in reproductive biology among species and geographic regions. Understanding of these differences is critical to the development of assisted reproductive technologies including estrus induction, gamete rescue, and embryo production techniques for canid conservation efforts. This review summarizes current knowledge of canid reproduction, including estrus cyclicity, seasonality, and seminal traits, with the emphasis on species diversity. The application of reproductive technologies in wild canid conservation will also be discussed.

Abstract:

Despite the worldwide increase of rhinoceros calf numbers, the growth of the population of white and black rhinoceros is slowing down mainly due to anthropogenic causes, such as poaching and habitat loss. Assisted reproduction is one of the methods of preserving the valuable genomes of these animals from being lost, and assists in breeding them in captivity to maintain the specie(s) numbers and provide an option for possible reintroduction into the wild. Since wild rhinoceros are difficult to handle and examine clinically, most of the current information available on their reproductive characteristics has been gained from captive rhinoceros populations. Nevertheless, very little is known about rhinoceros reproduction. Since the rhinoceros belongs to the odd-toed ungulates (Perissodactyls) group, like the horse and the tapir, the horse has been proposed as a suitable model to study reproduction and artificial reproductive techniques in the rhinoceros. In this review, the current knowledge of the reproduction of the rhinoceros is summarized.

Abstract:

Abstract Assisted Reproductive Techniques (ART s) have proposed a new way of understanding notions of sexuality, reproduction, gestation, and family, and these transformations have arguably been a challenge in the religious field. This study aims to analyze the stances taken within the Catholic spectrum in the United States on ART s. Catholicism in the United States is an internally heterogeneous space, and different agents have taken diverse stances on ART s, with an impact on health care regulations, Catholic facilities administrations, and Catholics’ and non-Catholics’ reproductive rights. Drawing from a qualitative, interpretive, and documentary analysis of three organizations (the US Conference of catholic bishops, the Catholic Health Organization, and Catholics for Choice), this article proposes some guidelines to analyze and understand the arguments and strategies of various Catholics actors in the United States regarding reproductive healthcare and ART s in the United States.

Full text

Abstract:

Introduction of alien species is a worldwide problem that accompanies human activity. Invasive alien ants (Hymenoptera: Formicidae) are among those predatory invertebrates that cause the greatest damage to native ecosystems and biodiversity, and their management is difficult. Therefore, novel environmental load–reducing (i.e., highly invasive alien ant–specific) management methods are required. In this review, we present novel potential methods of invasive alien ant management that would use microorganisms to manipulate reproduction in the host arthropod. In general, reproductive manipulators force costs against their hosts during reproduction. However, most of the manipulators themselves incur no, or little, cost during the usual life of the host. Therefore, reproductive manipulators can be especially effective against social insects. For example, reproductive manipulators can decrease mating chance for males by killing or feminizing males. In addition, manipulators that induce parthenogenesis or cytoplasmic incompatibility (herein abbreviated CI) may be useful in new techniques for generating sterile males for release. Transinfection with reproductive manipulators by using microinjection techniques has recently become available. This strategy should be of great help in developing and applying this novel management method.

Abstract:

In recent decades, the adverse effects of global warming on all living beings have been unanimously recognized across the world. A high environmental temperature that increases the respiration and rectal temperature of cattle is called heat stress (HS), and it can affect both male and female reproductive functions. For successful reproduction and fertilization, mature and healthy oocytes are crucial; however, HS reduces the developmental competence of oocytes, which compromises reproduction. HS disturbs the hormonal balance that plays a crucial role in successful reproduction, particularly in reducing the luteinizing hormone and progesterone levels, which leads to severe problems such as poor follicle development with a poor-quality oocyte and problems related to maturity, silent estrus, abnormal or weak embryo development, and pregnancy loss, resulting in a declining reproduction rate and losses for the cattle industry. Lactating cattle are particularly susceptible to HS and, hence, their reproduction rate is substantially reduced. Additionally, bulls are also affected by HS; during summer, semen quality and sperm motility decline, leading to compromised reproduction. In summer, the conception rate is reduced by 20–30% worldwide. Although various techniques, such as the provision of water sprinklers, shade, and air conditioning, are used during summer, these methods are insufficient to recover the normal reproduction rate and, therefore, special attention is needed to improve reproductive efficiency and minimize the detrimental effect of HS on cattle during summer. The application of advanced reproductive technologies such as the production of embryos in vitro, cryopreservation during the hot season, embryo transfer, and timed artificial insemination may minimize the detrimental effects of HS on livestock reproduction and recover the losses in the cattle industry.

Abstract:

L'auteure présente une partie des résultats d'une recherche effectuée sur les représentations sociales des nouvelles techniques de reproduction (NTR) chez des femmes ayant recouru à la médecine de la reproduction. Loin d'être univoque ou simple reproduction d'une logique médicale ou technicienne, le savoir des femmes est diversifié et complexe. Cinq représentations sont exposées, bien distinctes les unes des autres. Les NTR y apparaissent successivement comme des « moyens de contrôle », de l'« excès », des « moyens d'assistance et de réification », des « moyens d'expression de l'individualité » et, enfin, comme une « épreuve ».

Abstract:

Genomic imprinting is the parent-of-origin specific gene expression which is a vital mechanism through both development and adult life. One of the key elements of the imprinting mechanism is DNA methylation, controlled by DNA methyltransferase enzymes. Germ cells undergo reprogramming to ensure that sex-specific genomic imprinting is initiated, thus allowing normal embryo development to progress after fertilisation. In some cases, errors in genomic imprinting are embryo lethal while in others they lead to developmental disorders and disease. Recent studies have suggested a link between the use of assisted reproductive techniques and an increase in normally rare imprinting disorders. A greater understanding of the mechanisms of genomic imprinting and the factors that influence them are important in assessing the safety of these techniques.

Abstract:

Reproduction is the way to immortality for an individual, and it is essential to the continuation of the species. Sirtuins are involved in cellular homeostasis, energy metabolism, apoptosis, age-related problems, and sexual reproduction. Sirtuin 1 (SIRT1) belongs to the sirtuin family of deacetylases, and it is a nicotinamide adenine dinucleotide (NAD)-dependent deacetylase. It removes the acetyl group from a variety of substrates. SIRT1 regulates endocrine/metabolic, reproductive, and placental development by deacetylating histone, different transcription factors, and signal transduction molecules in a variety of cellular processes. It also plays a very important role in the synthesis and secretion of sex hormones via regulating the hypothalamus-pituitary-gonadal (HPG) axis. Moreover, SIRT1 participates in several key stages of spermatogenesis and sperm maturation. The current review will give a thorough overview of SIRT1’s functions in male reproductive processes, thus paving the way for more research on restorative techniques and their uses in reproductive medicine.

Abstract:

Las Técnicas de Reproducción Humana Asistida (TRHA) constituyen innovaciones que, en el espacio social, dan cuenta de los procesos de gobernabilidad reproductiva, tensionando definiciones de reproducción, familia, parentesco y persona. En el caso argentino, estas definiciones, por su acceso, se dirimieron en gran medida en el escenario jurídico y legislativo. Tomando el debate legislativo argentino, este artículo analiza las argumentaciones de las posiciones a favor y de las oposiciones conservadoras a la hora de regular el acceso de la población a las TRHA. Mediante una metodología cualitativa, se realiza un análisis de contenido de documentos y versiones taquigráficas del debate legislativo por la regulación de las TRHA (2012-2013) en el Congreso de la Nación Argentina, retomando los principales ejes de debate: las nociones de sexualidad, de familia y de reproducción, así como las disputas sobre el estatus del embrión producto de estas técnicas. The Assisted Reproduction Techniques (ARTs) constitute innovations that in the social space account for the processes of reproductive governance, stressing definitions of reproduction, family, kinship, and person. In the Argentine case, these definitions for their access were primarily resolved in the legal and legislative scenarios. From the Argentine legislative debate, this article analyzes the arguments of positions in favor and conservative oppositions, when regulating the access of the population to the ARTs. Through a qualitative methodology, analysis of the content of documents, and shorthand versions of the legislative debate for the regulation of the ARTs (2012-2013) in the Argentine National Congress. This is carried out taking up the principal axes of discussion: the notions of sexuality, of family, reproduction as well as disputes about the status of the embryo product of these techniques.

Abstract:

However, reproduction in sheep is seasonal, many breeds of sheep are able to mate not only in autumn, but out-of-season as well. The main factor determining seasonality is the photoperiod, but other factors can influence reproductive pattern, such as genetics, management practices and social cues. The fertility of spring and early summer breeding is usually lower; this imposes the need for alternative methods (e.g. hormonal treatments, biotechnological practice), to increase the conception rate.The author summarize the main practical techniques and biotechnological methods for controlling reproduction completed with some own experimental results in connection with different topics.

Abstract:

Cryopreservation of human spermatozoa—introduced in the 1960's—has been recognized as an efficient procedure for management of male fertility before therapy for malignant diseases, vasectomy or surgical infertility treatments, to store donor and partner spermatozoa before assisted reproduction treatments and to ensure the recovery of a small number of spermatozoa in severe male factor infertility. Despite the usefulness of it, cryopreservation may lead to deleterious changes of sperm structure and function: while the effects of cryopreservation on cells are well documented, to date there is no agreement in the literature on whether or not cryopreservation affects sperm chromatin integrity or on the use of a unique and functional protocol for the freezing-thawing procedure. Therefore, sperm cryopreservation is an important component of fertility management and much of its successful application seems to affect the reproductive outcome of assisted reproduction technologies (ART): appropriate use of cryoprotectants before and sperm selection technologies after cryopreservation seem to have the greatest impact on preventing DNA fragmentation, thus improving sperm cryosurvival rates.

Abstract:

Reproduction and spawning of the scallop Pecten novaezelandiae were monitored at four sites in the Hauraki Gulf, New Zealand, from July 2000 to July 2001. A visual grading system based on the macroscopic appearance of the gonad was developed and tested, and changes in visual grade, quantitative histology, and standardised gonad mass were used to describe seasonal and spatial patterns in gametogenesis and spawning. Visual grade was significantly correlated with histological and gonad mass data (r 2 = 0.74–0.87) and validated as an accurate method for measuring reproduction in P. novaezelandiae. Visual grading facilitates rapid assessment of reproductive condition and can be conducted non-destructively, thus providing a tool allowing long-term studies of individual spawning behavior in relation to environmental signals. Scallops exhibited episodic spawning, with spawning events detected in spring, summer, autumn, and even early winter. Gonad recovery and subsequent gamete development and maturation were apparent between spawnings. Within-season variability in gonad size and condition could be the result of multiple (serial) spawnings during a season. The timing of spawning varied among populations, probably reflecting differences in environmental conditions that influenced reproduction. However, the largest spawning events occurred at all sites in early summer (December/January), coincident with wind-driven upwelling conditions.

Abstract:

Problems of female subfertility are a current challenge. Implant failure of the embryo after an assisted human reproduction technique is undesirable and unpleasant, and strategies to improve this implant rate are welcome. One of these techniques is endometrial scratching. We performed a literature review by searching in the PubMed and Cochrane databases for relevant information regarding the technique of endometrial scratching. The technique of endometrial scratching is not complex, but choosing an optimal period in the menstrual cycle seems to produce the desired effects for the successful implantation of the embryo. Pregnancy rates obtained through assisted human reproduction techniques have been improved due to endometrial scratching techniques.
