Inhibitory actions of Anti-Müllerian Hormone (AMH) on ovarian primordial follicle assembly. [PDF]

PLoS ONE, 2011
The current study was designed to investigate the actions of Anti-Müllerian Hormone (AMH) on primordial follicle assembly. Ovarian primordial follicles develop from the breakdown of oocyte nests during fetal development for the human and immediately ...

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-

Roles of follicle stimulating hormone and sphingosine 1-phosphate co-administered in the process in mouse ovarian vitrification and transplantation

Journal of Ovarian Research, 2023
Some major challenges of ovarian tissue vitrification and transplantation include follicle apoptosis induced by cryopreservation and ischemia-reperfusion injury, as well as ovarian follicle loss during post-transplantation.

Germ–Somatic Cell Interactions Are Involved in Establishing the Follicle Reserve in Mammals

Frontiers in Cell and Developmental Biology, 2021
Mammalian females are born with a finite reserve of ovarian follicles, the functional units of the ovary. Building an ovarian follicle involves a complex interaction between multiple cell types, of which the oocyte germ cell and the somatic granulosa ...

The effects of electromagnetic fields on the number of ovarian primordial follicles: An experimental study

Kaohsiung Journal of Medical Sciences, 2015
The aim of this study was to evaluate the effect of an electromagnetic field (EMF), generated close to the ovaries, on primordial follicles. A total of 16 rats were used in this study.

Bioengineering the Ovarian Follicle Microenvironment [PDF]

Annual Review of Biomedical Engineering, 2014
Chemo- and radiation therapies used to treat cancer can have the unintended effect of making patients infertile. Clinically established fertility preservation methods, such as egg and embryo cryopreservation, are not applicable to all patients, which has motivated the development of strategies that involve ovarian tissue removal and cryopreservation ...

Stepped vitrification technique for human ovarian tissue cryopreservation [PDF]

, 2019
The advantage of stepped vitrification (SV) is avoiding ice crystal nucleation, while decreasing the toxic effects of high cryoprotectant concentrations. We aimed to test this method for human ovarian tissue cryopreservation.
