Role of Sex Hormone Receptors in Ovulation

open access: yesTaiwanese Journal of Obstetrics & Gynecology, 2005
Sex hormones including progestins, androgens, and estrogens produced de novo from cholesterol within the ovary play important roles in the growth and differentiation of reproductive tissues and in the maintenance of fertility.

Reproductive management in pigs: emphasis on the different roles of the boar and on optimal insemination management [PDF]

open access: yes, 2009
Boars have different roles in the reproductive management in pigs. Boar contact can stimulate follicle development and thereby induce oestrus, both in gilts and sows.

Ketoconazole Inhibits Ovulation as a Result of Arrest of Follicular Steroidogenesis in the Rat Ovary [PDF]

open access: yes, 2014
Objective Ketoconazole (KCZ) is a known inhibitor of steroidogenic P450 enzymes in the adrenal cortex and the gonads. Previous studies examined the potential clinical use of KCZ for attenuation of ovarian response to gonadotropin treatments.

Functional Sex Reversal in Adult Gonochoristic Teleosts is Mediated by Ovarian Germline Stem Cell Plasticity and Somatic Cell Transdifferentiation

open access: yesAdvanced Science, EarlyView.
Oocytes play crucial roles in maintaining ovarian fate in adult gonochoristic fish. Targeted oocyte ablation with aromatase inhibition triggers the activation of surviving germline stem cells and the transdifferentiation of somatic cells from granoulosa/theca to Sertoli/Leydig lineages, inducing a complete and functional female‐to‐male sex reversal ...

Association between menstrual cycle phases and exposure to environmental contaminants— Menstrual Cycle and Ovulation Study 2 (MOS2)

open access: yes, 2022
In 2006-2008, 610 premenopausal, spontaneously menstruating women in the Metro Vancouver region participated in a Canadian Institutes of Health Research (CIHR)-funded singlecycle in which they collected first morning urine specimens for estrogen and ...

Effect of L-carnitine supplementation on fertility outcomes among patients with polycystic ovary syndrome: a systematic review and dose-response meta-analysis of randomized clinical trials [PDF]

open access: yesObstetrics & Gynecology Science
This systematic review and meta-analysis of randomized controlled trials (RCTs) assessed the effect of L-carnitine (LC) supplementation on the fertility outcomes of patients with polycystic ovary syndrome (PCOS). Online databases (Scopus, Web of Science,

Unraveling ovarian histology: The key morphological aspects that spur the development of the Fossa ovarii in equine

open access: yesThe Anatomical Record, EarlyView.
Abstract The equine ovary exhibits unique structural and developmental features that distinguish it from those of other domestic species, including the presence of an ovulation fossa and an inversion of cortical and medullary layers. This study aimed to investigate the morphostructural development of the equine fetal ovary, with particular emphasis on ...

Correlation between obesity and successful ovulation induction with Clomiphene citrate [PDF]

open access: yes, 2022
Ovulation induction with clomiphene citrate is a hormonal therapy for infertile women with impaired ovarian function caused by dysregulation of the hypothalamus and pituitary, affecting egg development and ovulation.

Tracing the evolutionary history of the morpho‐anatomy of baculum in primates

open access: yesThe Anatomical Record, EarlyView.
Abstract Animal morphology reflects both evolutionary history and present‐day adaptation. Male mammal copulatory structures such as the baculum (penile bone) are ideal for studying these processes because of their complexity and high interspecific variability. In primates, however, research has focused mostly on baculum length.
