A Narrative Review of Recent Insights on Nerve Growth Factor Signaling in Physiological and Pathological Ovarian Processes in Mammals [PDF]

open access: yesBiomolecules
Nerve Growth Factor (NGF), a member of the neurotrophin family, is currently regarded as a key regulator of ovarian physiology beyond its well-known neurotrophic functions.

Integrative Transcriptome Analysis Across Follicles Highlights Key Regulatory Pathways in Low and High-Egg-Laying Hens [PDF]

open access: yesAnimals
Egg-laying performance in hens is regulated by complex molecular mechanisms within the hypothalamic–pituitary–gonadal (HPG) axis and ovarian follicles. This study employed integrative transcriptome profiling of primordial (PR), primary (PM), small white (

A Feasible Option before Cycle Cancellation for Poor Responders; STOP-START Protocol [PDF]

open access: yesInternational Journal of Fertility and Sterility, 2021
Despite the advances in controlled ovarian stimulation (COS), management of a subgroup of poor ovarian responderpatients may still be challenging. We describe a feasible and simplified protocol, namely the STOP-START protocol,for poor responders defined ...

Intercellular communication in the cumulus–oocyte complex during folliculogenesis: A review

open access: yesFrontiers in Cell and Developmental Biology, 2023
During folliculogenesis, the oocyte and surrounding cumulus cells form an ensemble called the cumulus-oocyte complex (COC). Due to their interdependence, research on the COC has been a hot issue in the past few decades.

Geographical Diversity in the Age Specific Anti Müllerian Hormone Levels in Infertile Women: A Hospital Based Cohort Study

open access: yesJournal of Human Reproductive Sciences, 2023
Background: Serum anti-Mullerian hormone (AMH) is a significant determinant of ovarian reserve. It is still not clear about the rate at which AMH declines with age and varies across populations.

Dynamic transcriptome and chromatin architecture in granulosa cells during chicken folliculogenesis

open access: yesNature Communications, 2022
The domestic chicken Gallus gallus domesticus is a classic model for the study of folliculogenesis. Here the authors integrate multi-omics analyses characterizing the dynamic transcriptome and chromatin architecture in granulosa cells during chicken ...

Potential biomarkers to predict return to fertility after discontinuation of female contraceptives—looking to the future

open access: yesFrontiers in Reproductive Health, 2023
Nowadays there are multiple types of contraceptive methods, from reversible to permanent, for those choosing to delay pregnancy. Misconceptions about contraception and infertility are a key factor for discontinuation or the uptake of family planning ...

Role of certain growth factors and hormones in folliculogenesis

open access: yesIndian Journal of Animal Sciences, 2020
Folliculogenesis is an inextricable process associated with female fertility and infertility cases. This process involves many events at cellular and molecular level in a highly orchestrated fashion which culminates with ovulation.

Squeezing the eggs to grow: The mechanobiology of mammalian folliculogenesis

open access: yesFrontiers in Cell and Developmental Biology, 2022
The formation of functional eggs (oocyte) in ovarian follicles is arguably one of the most important events in early mammalian development since the oocytes provide the bulk genetic and cytoplasmic materials for successful reproduction.

Ovary Development: Insights From a Three-Dimensional Imaging Revolution

open access: yesFrontiers in Cell and Developmental Biology, 2021
The ovary is an indispensable unit of female reproduction and health. However, the study of ovarian function in mammals is hindered by unique challenges, which include the desynchronized development of oocytes, irregular distribution and vast size ...
