The effect of follicular fluid hormones on oocyte recovery after ovarian stimulation: FSH level predicts oocyte recovery

BACKGROUND Ovarian stimulation for assisted reproductive technology (ART) overcomes the physiologic process to develop a single dominant follicle. However, following stimulation, egg recovery rates are not 100%. The objective of this study is to determine if the follicular fluid hormonal environment is associated with oocyte recovery. METHODS This is a prospective study involving patients und...

Steroid profiles in ovarian follicular fluid from regularly menstruating women and women after ovarian stimulation.

BACKGROUND Information on the concentrations of steroids in ovarian follicular fluid (FF) from regularly menstruating (RM) women has been limited because of the absence of methods for the simultaneous quantification of multiple steroids in small volumes of FF. We studied steroid profiles in FF during the early follicular phase of the menstrual cycle and after ovarian stimulation for in vitro fe...

Follicular Development and Oocyte Growth

Follicular development begins as early as the fourth month of fetal life [1]. At that time, the primordial germ cells (PGCs) have migrated from the yolk sac endoderm to the gonadal ridge, undergoing mitotic divisions. PGCs are called oogonia once they reach the gonads, then the oogonia enter the first meiotic division and become primary oocytes. Somatic cells originating from the primitive gona...

Control of oocyte meiotic maturation and fertilization.

Sexual reproduction depends upon meiosis for the generation of haploid gamete nuclei, which unite after fertilization to form the diploid zygote. The oocytes of most animal species arrest during meiotic prophase, and complete meiosis in response to intercellular signaling in a process called meiotic maturation. Oocyte meiotic maturation is defined by the transition between diakinesis and metaph...

Follicular cells acquire sertoli cell characteristics after oocyte loss.

Although it has been suggested that in mammals the loss of female germ cells may induce the masculinization of the ovarian compartment, there has been as yet no conclusive demonstration. To directly address that question, the present study has been designed to determine the fate of follicular cells after oocyte loss. Using gamma-irradiation to selectively deplete oocytes in nongrowing follicles...
