Abstract:

To cope with seasonally varying ecological constraints, some mammals temporally suppress breeding or delay their first reproduction. In field conditions, mound-building mice (Mus spicilegus) born in spring begin to reproduce when 2–3 months old, whereas individuals born at the end of summer delay their first reproduction for 6–8 months until the following spring. In order to test age effects on reproductive performance in M. spicilegus, sexually naïve mice were paired when 2–3 months old or at 6–8 months of age, and surveyed for reproduction. We show here that under laboratory conditions the a

Abstract:

The potential impact of two parasites on the population density of host white-footed mice (Peromyscus leucopus) was assessed by measuring effects on survival and reproduction in field populations. Thirty-eight mice infected with larvae of the bot fly Cuterebra angustifrons had their larvae removed, another 41 mice remained infected, and 46 other mice were naturally uninfected during the experiment. No effect of bot larvae removal was detected on either survival (measured as attrition) or reproduction (measured as end of reproductive season). However, contrary to expectation, naturally infected

Abstract:

The present study aimed to examine whether transplacental exposure to progesterone caused male reproductive abnormalities and whether the changes can be reversed after testosterone administration. Progesterone was injected to mice on day 1, 3, and 7 of pregnancy. The male pups (F1 generation) were allowed to grow for 50 days and assessed for reproductive performance. Gestational exposure to progesterone (7 mg/kg body weight) resulted in significant body weight gain with a decrease in reproductive tissue indices in mice.

Abstract:

Peroxisome proliferator-activated receptors (PPARs) are ligand-activated nuclear receptors controlling many important physiological processes, including lipid and glucose metabolism, energy homeostasis, inflammation, as well as cell proliferation and differentiation.

Abstract Cyclooxygenase (COX)-derived prostaglandins are critical in female reproduction.

The results demonstrate that simultaneous inhibition of COX-1 and COX-2 produces more severe effects on early pregnancy events than inhibition of ei

Abstract:

AbstractAlthough most research has focused on maternal obesity, there is growing data to indicate that obesity in the father can affect reproduction. Supporting data come from both mouse and human studies. Murine studies found that obese male mice exhibited decreased motility and reduced hyperactivated progression versus lean mice. Obese mice also exhibited sperm with increased levels of intracellular and mitochondrial levels of reactive oxygen species, increased sperm damage, and lower levels of capacitation, which has been shown to be associated with poor fertilization rates following in vit

Abstract:

The biological actions of prolactin (PRL), a polypeptide hormone, are mostly related to lactation and reproduction. These actions have been clarified by studies of PRL and PRL-deficient receptor mice, which have a clear phenotype of reproductive failure at multiple sites. This review aims to summarize current knowledge about PRL and its receptor, role in reproductive axis and presents information of hyperprolactinemia in reproductive medicine. Our understanding of the physiology and transduction pathway of PRL has largely increased in the past 20 years with the cloning of PRL and its receptor

Abstract:

ABSTRACT Many growth factors and hormones modulate the reproductive status in mammals. Among these, insulin and insulin-like growth factor I (IGF-I) regulate the development of gonadal tissues. SH2-B has been shown to interact with insulin and IGF-I receptors, although the role of SH2-B in these signals has not been clarified. To investigate the role of SH2-B, we generated mice with a targeted disruption of the SH2-B gene. Both male and female SH2-B−/− mice showed slight retardation in growth and impaired fertility. Female knockout mice possess small, anovulatory ovaries with reduced numbers o

Abstract:

There is strong epidemiological evidence indicating that disruption of the endogenous circadian rhythms can cause a range of health problems ranging from metabolic and cardiovascular disorders to reproductive failure. Circadian rhythmicity is generated by a suite of genes called ‘clock genes’ that are cyclically expressed in the brain and peripheral tissues. The CLOCK and BMAL1 transcription factors regulate the expression of many genes involved in cell growth, angiogenesis and development. The Bmal1 knockout mouse provides an interesting model to analyse the impact of arrhythmicity on reprodu

Natural genetic variation in reproduction and life history strategies is a manifestation of variation in underlying regulatory neuronal and endocrine systems. A test of the hypothesis that genetic variation in luteinizing hormone (LH) level could be related to a life history trait, seasonal reproduction, was conducted on artificial selection lines from a wild-source population of white-footed mice ( Peromyscus leucopus ). Variation exists in the degree of suppression of reproduction by winter short-day photoperiods (SD) in wild-source individuals and in the laboratory population. In this popul

The menstruating Egyptian spiny mouse has recently been proposed as a new animal model for reproductive health research. Unfortunately, little is known about reproduction in males. This study compared several characteristics of sperm function before and after cryopreservation. Epididymal spermatozoa were cryopreserved in different concentrations of raffinose and skim milk and tested for motility and membrane integrity (Experiment 1). Further evaluations of motility, plasma membrane and acrosome integrity, mitochondrial membrane potential and DNA integrity were conducted with the addition of l-

Estrogen receptor-α (Esr1) mediates estrogen action in regulating at all levels of the hypothalamic-pituitary-ovarian axis. Whereas the importance of Esr1 in hypothalamus and pituitary has been demonstrated by loss of fertility in the neuron- and pituitary-specific Esr1 knockout mice, whether Esr1 plays a critical role in the ovary remains to be determined. In the ovary, Esr1 is mainly expressed in the theca/interstitial cells and germinal epithelium and thus is believed to mediate estrogen action in these cells. In this study, we assessed the importance of Esr1 in the ovarian theca cells in r

We have analyzed the expression of the mouse mesothelin gene in different developmental stages and in various adult tissues by Northern hybridization. The 2.5-kb mesothelin transcript was detected in the mRNA of E 7.0, E 15.0, and E 17.0 stages of mouse development. In adult tissues the mesothelin gene was expressed in lung, heart, spleen, liver, kidney, and testis. To directly assess the

Previous studies have shown that thioglycolic acid (TGA) leads to potential reproductive toxicology. To clarify the exact effects of this compound on reproduction, mice oocytes were treated with different TGA doses. At the end of the culture period, the nuclear status of mice oocytes was assessed under an inverted microscope. After immunofluorescence staining, the chromosomal arrangement and spindle configuration of oocytes were evaluated. The results indicated that TGA decreases the percentage of first polar body formation but does not influence that of germinal vesicle breakdown. TGA induces

Abstract:

Kisspeptin is vital for the neuroendocrine regulation of GNRH secretion. Kisspeptin neurons are now recognized as a central pathway responsible for conveying key homeostatic information to GNRH neurons. This pathway is likely to mediate the well-established link between energy balance and reproductive function. Thus, in states of severely altered energy balance (either negative or positive), fertility is compromised, as isKiss1expression in the arcuate nucleus. A number of metabolic modulators have been proposed as regulators of kisspeptin neurons including leptin, ghrelin, pro-opiomelanocorti
