Rodent Models of Polycystic Ovary Syndrome [PDF]

, 2013
Rodents are clearly valuable models for assessing disruption of fertility. The effects of different steroid treatments at different stages of reproductive life through from fetal to adult have been assessed for effects on fertility, ovarian morphology ...

Estrous behavior in dairy cows: identification of underlying mechanisms and gene functions [PDF]

, 2010
Selection in dairy cattle for a higher milk yield has coincided with declined fertility. One of the factors is reduced expression of estrous behavior. Changes in systems that regulate the estrous behavior could be manifested by altered gene expression ...

Interaction of Follicle-Stimulating Hormone and Stem Cell Factor to Promote Primordial Follicle Assembly in the Chicken

Frontiers in Endocrinology, 2019
Follicle-stimulating hormone (FSH) and KIT signaling are required for ovarian development. In this study the interactive effect of FSH and stem cell factor (SCF) on folliculogenesis was investigated in the chicken.

Spermatogenesis and sertoli cell activity in mice lacking Sertoli cell receptors for follicle stimulating hormone and androgen [PDF]

, 2008
Spermatogenesis in the adult male depends on the action of FSH and androgen. Ablation of either hormone has deleterious effects on Sertoli cell function and the progression of germ cells through spermatogenesis.

PACAP induces FSHβ gene expression via EPAC. [PDF]

, 2019
Gonadotropins, luteinizing hormone (LH) and follicle-stimulating hormone (FSH), are heterodimers of a common α subunit and unique β subunits. Regulation of their levels, primarily by GnRH, is critical for reproductive function.

Activity of 3β-hydroxysteroid dehydrogenase associated with progesterone production in bovine granulosa cells cultured under different concentrations of serum, insulin-like growth factor I, and gonadotropin [PDF]

, 2014
Three-β-hydroxysteroid dehydrogenase (3β-HSD) is the enzyme responsible for progesterone production. This study aimed to determine whether 3β-HSD activity can be shown to reflect progesterone production by granulosa cells cultured under different serum

Can Testicular Size Be a Predictive Factor for Successful Sperm Retrieval in Patients with Non Obstructive Azoospermia?

Gynecology Obstetrics & Reproductive Medicine, 2019
Objective: Non-obstructive azoospermia, defined as absence of spermatozoa in the ejaculate caused by impaired spermatogenesis, is the most severe cause of male infertility.

Predictive factors for ovarian response in a corifollitropin alfa/GnRH antagonist protocol for controlled ovarian stimulation in IVF/ICSI cycles [PDF]

, 2015
Background This secondary analysis aimed to identify predictors of low (<6 oocytes retrieved) and high ovarian response (>18 oocytes retrieved) in IVF patients undergoing controlled ovarian stimulation with corifollitropin alfa in a gonadotropin-
