Hormones and Preantral Follicle Growth in Women
Mayo Clinic Proceedings, 1976Studies of follicular morphology in biopsies of human ovarian tissue obtained from women with a syndrome of hypogonadotropic hypogonadism have been reviewed. Follicular maturation was consistent with that seen in ovarian tissues removed at postmortem examination of infants.

In vitro development of caprine ovarian preantral follicles
Theriogenology, 2000The in vitro growth and developmental pattern of caprine preantral follicles cultured in agar gel was observed. Preantral follicles 50 to 150 microm in diameter were isolated from prepuberal goat ovaries by treatment with collagenase and DNase. The isolated preantral follicles were cultured in agar gel for up to 14 days.

Cellular Reprogramming, 2018
One of the most important concerns cancer survivors face is fertility. Current treatment modalities often result in damage to the reproductive system. Different options have been proposed to preserve the fertility of affected women, and many attempts have been made to improve their chance of childbearing after therapy.

In vitro folliculogenesis of rat preantral follicles.
Endocrinology, 1995The impact of various gonadotropic hormones on the growth and development of secondary follicles from primordial and primary follicles obtained by enzymatic dissociation of the ovaries of immature 14-day-old rats was studied in vitro. The substratum-adherent culture technique developed for studying folliculogenesis in the current study permitted direct

Xenobiotic effects on ovarian preantral follicles.
Biology of reproduction, 2012Women are born with a finite population of ovarian follicles, which are slowly depleted during their reproductive years until reproductive failure (menopause) occurs. The rate of loss of primordial follicles is determined by genetic and environmental influences, but certain toxic exposures can accelerate this process.

In vitro culture of buffalo (Bubalus bubalis) preantral follicles
Theriogenology, 2002Growth of buffalo preantral follicles in culture was studied to investigate the effect of size of preantral follicles, individual or group culture, long-term culture of preantral follicles for (40 days), addition of human follicle stimulating hormone (FSH), insulin-transferrin-selenium (ITS), growth factors (epidermal growth factor (EGF), fibroblast ...

Isolation and long-term culture of human preantral follicles
Fertility and Sterility, 1993To isolate intact preantral follicles from the human ovary for in vitro studies.Premenopausal human ovary was digested by a mixture of collagenase and deoxyribonuclease (DNase) for 1 hour at 37 degrees C and for 36 hour at 4 degrees C. Intact preantral follicles at classes 1 and 2 were isolated and cultured for up to 120 hours in a serum-free Dulbecco ...

Methods for Equine Preantral Follicles Isolation: Quantitative Aspects
Reproduction in Domestic Animals, 2013ContentsThe aim of this study was to test the use of mechanical and mechanical‐enzymatic methods, saline solution (SS), and PBS solution for the manipulation and isolation of mare ovarian preantral follicles (PAFs). The ovaries were subjected to mechanical isolation (mixer) alone or in association with enzymatic digestion (collagenase).

Effect of sectioning on the number of isolated ovine preantral follicles
Small Ruminant Research, 2000The aim of the present study was to test the effect of the interval of serial sections in the tissue chopper on the number of isolated ovine preantral follicles. Best results were obtained when the ovarian fragments were cut in the tissue chopper at interval of 87.5µm (1592 preantral follicles per treatment).
