Inhibin A and B secretion in mouse preantral follicle culture [PDF]
Human Reproduction, 1998 Conditioned media from single mouse ovarian follicles cultured from the early preantral stage up to complete maturity were analysed for different immunoreactive inhibin forms. The inhibin assays measured (i) alpha-specific inhibin, as represented by a mix of 32 and and 57 kDa inhibins, inhibin precursors, alpha-subunit and its precursors; (ii) dimeric ...

Cryopreservation and characterization of canine preantral follicles
Cryobiology, 2018 The aim of this study was to define the population, morphological and ultrastructural characteristics of bitch preantral follicles (PAFs) and to compare the effects on the morphology of PAF of two cryopreservation techniques - slow freezing (SF) and vitrification (V) - of bitches' ovarian tissue. The average population (number per ovary) of PAFs was 48,

In vitro development of pig preantral follicles [PDF]
Bioscientifica Proceedings, 2020 A limiting factor to realizing the full potential of many of the new reproductive techniques is the lack of abundant numbers of fertilizable oocytes. This problem could be addressed by using the large source of oocytes available from preantral and primordial follicles by developing systems for in vitro growth.

In Vitro Growth of Preantral Follicle and Maturation of Intrafollicular Oocyte from Aged Mice
Journal of Animal Reproduction and Biotechnology, 2019 This study aimed to recover the ovarian function through in vitro culture of preantral follicles from aged mice. First, we isolated the preantral follicles from ovaries of sixty-seven-week old B6D2F1 mice with decreased fecundity to know how many ...

Ovarian features in white-tailed deer (Odocoileus virginianus) fawns and does.
PLoS ONE, 2017 The knowledge about ovarian reserve is essential to determine the reproductive potential and to improve the methods of fertility control for overpopulated species, such as white-tailed deer (Odocoileus virginianus). The goal of this study was to evaluate

Nature Communications, 2022 Vitrification of preantral follicles is a promising strategy for female fertility preservation, but requires high concentrations of toxic cryoprotectants. Here, the authors accomplish follicle vitrification with low cryoprotectants by taking advantage of

Anti-Mullerian hormone attenuates the effects of FSH on follicle development in the mouse ovary [PDF]
, 2001 Although ovarian follicle growth is under the influence of many growth factors and hormones of which FSH remains one of the most prominent regulators.

Cryopreservation of Preantral Follicles
, 2018 In mammals, the total number of female germ cells is already established by the time of birth, meaning that no mitosis will take place in oogonias thereafter. Their cryostorage, therefore, depends on ovarian tissue manipulation. As an alternative to mature oocyte cryopreservation, the maintenance of inactive preantral follicles is a remarkable option ...
