Antiandrogens and Development of the Male Rat Reproductive Tract
… were to investigate the development of male reproductive tract malformations secondary to in utero DBP exposure from the fetus to the adult, to characterize the effects of DBP on fetal testicular gene expression for the steroidogenic enzymes, and to further explore DBP's potential for …

Dissecting the spatio-temporal development of the human reproductive tract
The human reproductive tract plays a crucial role in fertility and overall health due to the systemic effect of sex hormones. Its development depends on tightly regulated processes of sex differentiation, spatial patterning, and morphogenesis, which, when disrupted, can lead to congenital …

Localization of nerve growth factor-β in the stallion reproductive tract
… factor-β (NGF-β) is a protein produced in the reproductive tract of camelids (camels, llamas, and alpacas) that has been identified as the ovulation inducing factor in seminal plasma. NGF-β from seminal plasma deposited into the reproductive tract of the female camelid acts systemically to …

Estrogen Receptors and Estrogen-Regulated Genes in the Male Reproductive Tract
… steroid receptor localizations in the male reproductive tract. Therefore, in the first part of this thesis, the cellular expression of androgen (AR) and estrogen receptors, ERalpha and ERbeta, were investigated by immunohistochemistry in the adult male mouse reproductive tract. It was …

Female Reproductive Tract Fluids and Their Influence on Capacitation of Bovine Spermatozoa
Uterine, oviducal and follicular fluids were analyzed for protein, steroids and metabolic substrates based on stage of the cycle and follicular size respectively. Uterine fluids contained more protein than oviducal fluids and pyruvate and lactate concentrations in both fluids showed an inverse …

Pregnancy Induced Alterations of Reproductive Tract Collagen and Elastin in a Murine Model
… on structural and dynamical modifications of reproductive tract elastin and collagen as a function of parity. Pelvic floor dysfunction, including pelvic organ prolapse (POP) is a major concern affecting female health worldwide, leading to surgeries costing billions of dollars annually. …

A Functional Role of Estrogen in the Efferent Ductules of the Male Reproductive Tract
… in the efferent ductules (ED) of the male mouse reproductive tract at various biological levels. In spite of knowing the presence of high concentrations of estrogen and the existence of estrogen receptor (ER), ERalpha and ERbeta, in the male reproductive tract, a role for estrogen in the male …

What to Expect when Mice Are Expecting: Pregnancy-Driven Changes in the Reproductive Tract
… tearing, and pelvic organ prolapse. The female reproductive tract undergoes dramatic changes during pregnancy and postpartum recovery, requiring coordinated efforts across the vagina, cervix, and uterus. From an engineering perspective, we still do not know how much or why these forces change …

Influence of the female reproductive tract on the motility and morphological characteristics of ram spermatozoa
… are deposited in the posterior female reproductive tract but only a few hundred reach the oviducts and from these only one will fertilise an oocyte in a mono-ovulatory species. Investigating why so few spermatozoa reach the oviduct and what was so special about these spermatozoa was the …

Imagining the Internal Reproductive Environment: Function and Evolution of the Drosophila Melanogaster Female Reproductive Tract
… and potentially competition, among the reproductive cells, fluids, and structures of all individuals involved. For internally fertilizing species, these interactions occur within the body of one sex, predominantly the female, or ovary-associated, reproductive tract. Thus, characterizing …

Bacteriology of the reproductive tract of the peri parturient ewe and its relationship with fertility
… had not previously been recorded in the sheep reproductive tract. This study was affected by the occurence of Scrapie, which led to the culling of many of the ewes studied: Enzootic Abortion of Ewes (Chlamydophora abortus infection) which resulted in a whole flock treatment with parental …

Evidence That Relaxin Promotes Cellular Proliferation in the Lower Reproductive Tract of the Pregnant Rat
In summary, this is the first study to determined that relaxin promotes growth of the vagina during pregnancy in any species. Furthermore, this study also determined that the relaxin-induced growth of the cervix is brought about, in part, by promoting the cellular proliferation of cervical …

Impact of nutritional strategies on immunometabolic biomarkers, reproductive tract physiology and health of Holstein cows
Submission original under an indefinite embargo labeled 'Open Access'. The submission was exported from vireo on 2022-11-11 without embargo terms

Avian Infectious Bronchitis Virus: A Tropism for the Rooster Reproductive Tract and Effects on Reproductive Performance
… chickens. The pathogenesis of AIBV in the female reproductive tract has been well studied; however, there have been few studies concerning the effects of AIBV on the rooster reproductive tract. Therefore this investigation was undertaken to identify the role of AIBV in epididymal stone formation …

Tissue-Specific Mediation of Estrogen-Induced Epithelial Events by the Estrogen Receptor in Female Reproductive Tract Organs
… present in both stroma and epithelium of female reproductive tract organs. Although, the epithelial response to E2 has been assumed to be mediated directly through epithelial ER, indirect mediation by stromal ER may be responsible. The estrogenic response in reproductive tissues may also be …
