Abstract:

This study aims to evaluate the deleterious effect of the mycotoxin aflatoxin B1 (AFB1) on bull spermatozoa and the carryver effect on the developing embryo. Proteomic analysis of AFB1-treated spermatozoa revealed differential expression of proteins associated with biological processes and cellular pathways that involved in spermatozoon function, fertilization competence and embryonic development. Therefore, we assume that factors delivered by the spermatozoa, regardless of DNA fragmentation, are also involved. To confirm this hypothesis, we have used the annexin V (AV) kit to separate the spermatozoa into apoptotic (AV+) and non-apoptotic (AV−) subpopulations which were found to correlate with high- and low DNA fragmentation, respectively. Fertilization with AV+ AFB1-treated spermatozoa, resulted in no blastocyst formation, whereas fertilization with AV− spermatozoa resulted in reduced cleavage rate and formation of genetically altered blastocysts (POU5F1 and SOX2). Microarray analysis of blastocysts derived from 10 µM AFB1-treated spermatozoa revealed differential expression of 345 genes that involved in cellular pathways such as embryo and placenta development, cell cycle, DNA repair and histone modification, and in signaling pathways, especially calcium signaling pathway. This is the first report on deleterious carrying over effects of AFB1 from the bovine spermatozoa to the formed embryo. Our findings suggest that aside from the damage caused by AFB1 to spermatozoa’s DNA integrity, additional damage mechanisms are involved.

Abstract:

Abstract Atrazine (ATZ) is an extensively used herbicide and ubiquitous environmental contaminant. ATZ and its metabolite, diaminochlorotriazine (DACT), cause several cellular and functional alterations in spermatozoa. We aimed to examine the effect of ATZ/DACT on spermatozoon DNA integrity, fertilization competence, embryonic development, and transcriptome profile of in vitro-produced embryos derived from fertilization with pre-exposed sperm. Bovine spermatozoa exposed to ATZ (0.1 or 1 μM) or DACT (1 or 10 μM) during in vitro capacitation were used for in vitro fertilization of untreated oocytes. Cleavage and blastocyst-formation rates were evaluated 42 h and 7 days postfertilization, respectively. The association between DNA fragmentation and apoptosis (annexin V kit) was determined. Fertilization competence of annexin-positive (AV+) and annexin-negative (AV−) spermatozoa was examined. Microarray analysis was performed for 7-day blastocysts. Intracytoplasmic sperm injection was performed with control (AV+, AV−) and DACT (AV+, AV−) spermatozoa. Cleavage rates did not differ between groups and blastocyst formation tended to be higher for AV− vs. AV+ in both control and DACT groups, suggesting that acrosome reaction, rather than DNA fragmentation, underlies the reduced cleavage. Transcriptomic analysis revealed 139 and 230 differentially expressed genes in blastocysts derived from ATZ- and DACT-exposed spermatozoa, respectively, relative to controls. Proteomic analysis shown differential expression of proteins in ATZ- or DACT-treated spermatozoa, in particular proteins related to cellular processes and biological pathways. Therefore, we assume that factors delivered by the spermatozoa, regardless of DNA fragmentation, are also involved. Overall, the current study reveals a deleterious carryover effect of ATZ/DACT from the spermatozoa to the developing embryo.

Abstract:

One of the materials as potential candidates immunocontraception material is spermatozoa. Fertilin beta is spermatozoa membrane protein and is found only in mature spermatozoa and ejaculate, which serves as an adhesion molecule. Spermatozoa membrane protein that is used as an ingredient immunocontraception candidate, must have specific criteria that the specificity of spermatozoa, the role of antigen in the fertilization process, which includes the formation of immunogenicity sufficient antibody response has the potential to block fertilization. Antibodies against spermatozoa affect the stages before fertilization of the reproductive process and can hinder the development of the embryo after fertilization. Until now very little research data spermatozoa membrane protein as an ingredient immunocontraception are up to the test of experimental animals. The research objective is to prove the role of the resulting antibody induction of antibodies fertilin beta protein in the membrane of human spermatozoa induce agglutination and reduce motility thus reducing the number of in vitro fertilization. Research conducted at the IVF Laboratory, Department of Biology of Medicine, Faculty of Medicine, University of Airlangga. This research includes: Test the potential of antibody protein beta fertilin membrane of human spermatozoa and inhibit the role of antibodies in vitro fertilization in mice (Mus musculus Balb/c). In vitro studies have resulted in fertilization figure of 25% is smaller than the number that is equal to control fertilization of 58.7%, whereas previously the spermatozoa were incubated first with a beta membrane protein antibody fertilin human spermatozoa. While the percentage of inhibition of sperm to fertilize an oocyte by 33.75%. Potential imunokontraseptif considered effective if it decreased significantly (P <0.05) than the numbers fertilization in the treatment group compared with the control group. This shows fertilin beta membrane protein antibody has the ability to inhibit human spermatozoa to fertilize oocytes that reduce the number of fertilization.

Abstract:

SummaryWe studied whether bovine embryos developing after in vitro fertilization (IVF) with sex-sorted spermatozoa differed in developmental kinetics, quality and sex ratio from embryos produced with unsorted spermatozoa. Abattoir-derived oocytes were fertilized with X-sorted, Y-sorted or unsorted spermatozoa from a single bull. To evaluate economical use of the sex-sorted spermatozoa, washed spermatozoa from a single straw (2 million spermatozoa) were used to fertilize each batch of collected oocytes without any further isolation steps. Concentration of the unsorted spermatozoa was adjusted accordingly. Fertilizations were assessed by staining sperm asters at 10 hpi and pronuclei at 20 hpi. Embryo development and morphological quality were monitored on days 2, 7, 8 and 9 of the development (IVF = day 0). All embryos were sexed using PCR. Following fertilization, penetration and subsequent cleavage rates were compromised in the X-sorted group compared with the Y-sorted and unsorted groups (penetration: 58.0% vs. 89.8% and 90.0%, cleavage: 65.3% vs. 81.5% and 75.0%). The use of the sex-sorted spermatozoa did not, however, reduce the proportion of transferable embryos (sex-sorted 29.6% vs. unsorted 27.7%) or their quality (quality 1: sex-sorted 36.0% vs. unsorted 19.9%). The Y-sorted spermatozoa produced more transferable embryos of better quality than the X-sorted spermatozoa (days 7–8: 31.9% vs. 26.4%, quality 1: 38.9% vs. 30.6%). On average, out of 10 transferable embryos, nine were of the predicted sex in the X- and Y-sorted spermatozoa groups. These results indicate that low numbers of X- and Y-sorted spermatozoa can be used successfully for female and male embryo production in vitro.

Abstract:

: The spermatozoon has classically been seen only as a paternal DNA transporter into the oocyte, thus underestimating the entire contribution of the male gamete to the embryo development. The advancement of the research supports that not only the sperm genome, but the entire sperm transcriptome and proteome carry crucial information for fertilization and embryo development. : Altogether, 6871 proteins have been reported in spermatozoa so far. Their functional analysis has recently addressed to the sperm proteome a role in fertilization, preimplantation embryo development and paternal epigenetic inheritance. Targeted analysis of human spermatozoa is warranted to compile an evidence-based list of sperm-carried molecular targets in infertile patients.

Abstract:

SummaryDuring sea urchins fertilization, the activating spermatozoon triggers a series of physiological changes that transforms the quiescent egg into a dynamic zygote. It has been suggested that several of these egg activation events, e.g. sperm-induced plasma membrane depolarization and the Ca2+-linked cortical reaction, play additional roles to prevent the entry of supernumerary spermatozoa. In particular, the abrupt shift in egg membrane potential at fertilization, which is sustained by a Na+ influx, has been considered as a fast mechanism to block polyspermy. To test the relevance of the Na+-mediated fast electrical block to polyspermy, we fertilized sea urchin eggs in artificial seawater with a low concentration of Na+; nearly all the eggs were still monospermic, as judged by the number of Hoechst 33422-stained sperm. When fertilized in normal seawater, eggs that were pre-incubated in the low Na+ medium exhibited impaired elevation of the fertilization envelope. Nevertheless, these eggs manifested entry of a single spermatozoon, suggesting that the fertilization envelope was not the primary determinant of the block to polyspermy. Furthermore, we showed that the abnormal cleavage patterns displayed by eggs pre-incubated in low Na+, which were often considered a hallmark of polyspermy, were due to the alterations in the cortical actin filaments dynamics following fertilization, and not to the formation of multipolar spindles associated with supernumerary sperm centrosomes. Hence, our results suggested that Paracentrotus lividus eggs do not utilize Na+ to rapidly prevent additional spermatozoa from entering the egg, at variance with the hypothesis of an electrical fast block to polyspermy.

Full text

Abstract:

This paper describes the fine structure of the spermatozoan apex and its morphological changes during the process of fertilization in Ciona intestinalis. At the apex of the head an acrosome is present in the form of a flattened vesicle containing moderately electron-dense material with an electron-dense plate in its centre. Contiguous to the acrosome, an apical substance is located in the anterior-most tip of the sperm head. The spermatozoa that bind to and penetrate the chorion of both normal and caffeine-treated eggs have an intact acrosome and do not show an observable alteration of the plasmalemma enclosing the apex of the head. On the other hand, spermatozoa in the perivitelline space of both normal and caffeine-treated eggs lack an acrosome. Instead of an acrosome, apical processes are observed at the apex of the spermatozoa in the perivitelline space of both normal and caffeine-treated eggs. Gamete fusion seems to occur between the egg membrane and some of these apical processes at the tip of the sperm head. The apical process reported here is thought to be analogous to the acrosomal process in other marine invertebrates. The apical processes that are induced in the perivitelline space have not been previously described in ascidians.

Abstract:

To determine when the growing hamster oocyte gains the ability to fuse with the spermatozoon, oocytes at various stages of development were collected from ovaries, and zona-pellucida-free oocytes were inseminated in vitro with acrosome-reacted spermatozoa. Very small primary oocytes were unable to fuse with spermatozoa. Oocytes first became competent to fuse with spermatozoa when they had grown to about 20 microns in diameter. The acquisition of fusibility coincided with the first appearance of zona pellucida material and oolemma microvilli. The fusibility of the oolemma increased as the oocyte grew, reaching a maximum when the oocyte reached the metaphase of the second meiosis. The fusibility of the oolemma was reduced drastically after fertilization, and was lost completely by the 8-cell stage. The appearance and subsequent disappearance of a putative fusion-mediating molecule in the oolemma is proposed. Since this molecule is fairly resistant to proteinase digestion, at least in the hamster, it could be a cryptic protein or a glycolipid.

Abstract:

This study was conducted to determine if cryopreservation and thawing reduces the quality of scimitar-horned oryx spermatozoa and thus might be responsible for sub-optimal artificial insemination (AI) efficiency. Functional capacity of frozen–thawed oryx spermatozoa was compared in a heterologous bovine in vitro fertilization (IVF) system after being prepared by four methods. Fertilizing longevity was also assessed after thawing and pre-incubating spermatozoa for 12 or 24 h before IVF. Sperm characteristics (viability, morphology, acrosomal and capacitation status) were superior for samples prepared by Percoll centrifugation and standard swim-up compared with microdrop swim-up and wash methods. Regardless of variation in sperm characteristics over time, fertilization success and embryo development were high and did not differ among treatments. Fertilization and cleavage success for spermatozoa pre-incubated for 12 h before IVF were comparable with that achieved with non-incubated spermatozoa. Even 24 h after thawing, spermatozoa were capable of fertilizing oocytes, but percentage fertilization and embryo cleavage were significantly lower than for spermatozoa pre-incubated for 12 h. Overall, functional capacity of oryx spermatozoa after thawing appears comparable with that of domestic bull spermatozoa. When used for AI, frozen—thawed oryx spermatozoa should be capable of fertilizing oocytes in females ovulating 12 or even 24 h after insemination, providing sperm transport mechanisms are adequate. The functional capacity and fertilizing longevity of oryx sperm after thawing is high, and therefore unlikely to be responsible for decreased AI efficiency in the scimitar-horned oryx.

Abstract:

The following work demonstrates that paternal diet controls medically important metabolic phenotypes in offspring. We observe transmission of dietary information to the zygote via sperm, and this information evades reprogramming that typically occurs after fertilization. Cytosine methylation is implicated as a major contributor to meiotic epigenetic inheritance in several transgenerational phenomena. Our extensive characterization of the sperm methylome reveals that diet does not significantly affect methylation patterns. However, we find that extensive epivariability in the sperm epigenome makes important contributions to offspring variation. Importantly, coordinate cytosine methylation and copy number changes over the ribosomal DNA locus contributes to variation in offspring metabolism. Thus, rDNA variability acts independently of postadolescent paternal diet to influence offspring metabolism. Therefore, at least two mechanisms exist for epigenetically controlling offspring metabolism: stochastic epivariation and diet acting by an unknown mechanism to further modulate metabolism. This work argues that an offspring's phenotype can no longer be viewed solely as the result of genetic interactions with the developmental environment - the additional influences of paternal environment and inherited epigenetic variability must also be considered. These findings reveal novel contributions to metabolism that could revolutionize how we think about the risk factors for human health and disease.

Abstract:

The morphology and ultrastructure of spermatozoa are very diverse among the classes of the Crustacea, but how this diversity relates to sperm production and sperm economy has been little studied. A brief description of major forms and shapes of crustacean spermatozoa is provided and an overview of sperm ultrastructure is updated. Spermatogenesis is a costly process for males, as it requires considerable energy and time to achieve the required quality and quantity to guarantee success in fertilizing the eggs of females. Sperm are embedded in seminal fluids to preserve stored sperm and/or counteract the risk of sperm competition, which contributes significantly to the energy budget and sperm economy. In general, sperm are transferred in spermatophores of very diverse sizes and shapes within the different crustacean groups. Strategies related to sperm economy depend on the physical size of the partner, mating history, and perception of future mating opportunities. The mechanics involved in spermatogenesis and production of seminal fluids vary among the different crustacean classes and between different taxa. Sperm economy has direct links to sperm limitation in several male-centered fisheries. To better understand the evolutionary processes and to design suitable applied strategies (e.g., fisheries management or aquaculture), better knowledge is required about sperm histochemistry and functional morphology; furthermore, a wider taxonomic coverage is recommended by including commercial and non-commercial crustaceans beyond the decapods.
