Irisin alleviated the reproductive endocrinal disorders of PCOS mice accompanied by changes in gut microbiota and metabolomic characteristics

Frontiers in Microbiology
IntroductionFolliculogenesis and oligo/anovulation are common pathophysiological characteristics in polycystic ovary syndrome (PCOS) patients, and it is also accompanied by gut microbiota dysbiosis.

The role of cannabinoid agonists and antagonists on folliculogenesis and evolutionary events in the mouse ovary [PDF]

Iranian Journal of Basic Medical Sciences
Objective(s): Cannabinoids, derivatives of Cannabis sativa L., can activate the endocannabinoid system via two endogenous receptors, CB1 and CB2. This system is crucial in regulating folliculogenesis, fertility, and reproductive function.

Short oestrous cycles in sheep during anoestrus involve defects in progesterone biosynthesis and luteal neovascularisation [PDF]

, 2014
Anoestrous ewes can be induced to ovulate by the socio-sexual, 'ram effect'. However, in some ewes the induced ovulation is followed by an abnormally short luteal phase causing a so called, "short cycle".

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

The 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 ...

The NOBOX protein becomes undetectable in developmentally competent antral and ovulated oocytes [PDF]

, 2013
The oocyte-specific NOBOX protein is an important player during oocyte growth. Its absence in Nobox-/- mice arrests the transition from primordial to growing follicles and down-regulates the expression of a number of genes, including Oct4, a ...

Ontogeny of RSPO1, FOXL2, and RUNX1 during ovarian differentiation in the marsupial tammar wallaby

Developmental Dynamics, EarlyView.
Abstract Background RSPO1 and FOXL2 are female sex‐determining genes involved in the differentiation and organization of the ovary in some eutherian mammals. Mutations or loss of function of these genes are associated with partial to full sex reversal in mice, humans, and goats.

Expression of estrogen receptors alpha (ERs α) and folliculogenesis profile in ovary of the rats ovarian hypofunction model

Jurnal Ilmu-Ilmu Peternakan, 2021
Ovarian hypofunction is one of the reproductive disorders that occur due to a decrease in ovarian function that causes animals to not experience heat.

Folliculogenesis in the bovine [PDF]

Theriogenology, 1982
Abstract During the follicular phase of the estrous cycle in the cow, there is a rapid turnover in large (ovulatory size) follicles with the ovulatory follicle being identifiable by size not more than 3 days prior to estrus. Characteristics of the ovulatory follicle have been described in terms of steroid production and, to a lesser extent ...
