Physiology and Endocrinology: Female Reproduction

چکیده
stallions diluted at a ratio of 3:1 (extender: semen) with a commercially available stallion semen extender (Exodus Breeders Supply, York, PA) and packaged into each of the containers. Three sets of containers per season (winter and summer) where commercially shipped from Tucson, AZ to Springfield, MO with overnight delivery. Spermatozoal motilities were evaluated utilizing CASA following shipment. Containers were exposed to ambient temperatures that range from a high of 41◦C during the summer to a low of 5.5◦C during flight in the winter. Values for progressive motility of spermatozoa following 24 h of storage and shipment were similar (P > .05) for both cooling devices. Final storage temperatures following 24 h were similar (P > .05) for both devices. These data suggest that during both the winter and summer months in the southwestern United States, disposable cooling devices can be used to ship or cool stallion spermatozoa for 24 h.

The roles of RFamide-related peptides (RFRPs), mammalian gonadotropin-inhibitory hormone (GnIH) orthologues in female reproduction
Objective(s): To benefit from reproduction and deal with challenges in the environmental conditions, animals must adapt internal physiology to maximize the reproduction rate. Maladaptive variations in the neurochemical systems and reproductive system can lead to manifestation of several significant mammalian reprocesses, including mammalian ovarian lifespan. RFamide-related peptide (RFRP, Rfrp)...

متن کاملImmunological Aspects of Varicocele
Varicocele is the most common cause of infertility in men. The mechanism by which varicocele cause the variable effect on male infertility and is still unknown. Varicocele is found in 35 to 81 % of infertile men, and is one treatable form of male infertility. Although many advances have occurred in the treatment of varicocele, it still represents an important and challenging aspect of basic res...
متن کاملEndocrinology of year-round reproduction in a highly seasonal habitat: environmental variability in testosterone and glucocorticoids in baboon males.
In conditions characterized by energetic constraints, such as in periods of low food availability, some trade-offs between reproduction and self-maintenance may be necessary; even year-round breeders may then be forced to exhibit some reproductive seasonality. Prior research has largely focused on female reproduction and physiology, and few studies have evaluated the impact of environmental fac...
متن کاملNovel role of the anorexigenic peptide neuromedin U in the control of LH secretion and its regulation by gonadal hormones and photoperiod.
Neuromedin U (NMU) is a widely spread neuropeptide, with predominant expression at the gastrointestinal tract and brain, putatively involved in the regulation of a diversity of biological functions, including food intake, energy balance and circadian rhythms; all closely related to reproduction. Yet, the implication of NMU in the control of the gonadotropic axis remains scarcely studied. We rep...
