The relationship between follicular fluid steroid concentration and successful fertilization of human oocytes in vitro

Steroids and protein markers in the follicular fluid as indicators of oocyte quality in patients with and without endometriosis

“…In our IVF centre, more than 90% of the couples were referred for reasons of male infertility; our control population could thus be closer to the normal, fertile one which is reacting better to the gonadotrophin stimulation, resulting in higher FF estradiol levels. Our significantly increased estradiol levels together with the better pregnancy rates of the control group in our study correspond to the finding that fertilized oocytes came from follicles whose FF contained higher estradiol levels, and the best cleavage rate is obtained from follicles containing more estradiol (20). Data on leptin in the context of fertility are controversial.…”

Anti-Müllerian hormone substance from follicular fluid is positively associated with success in oocyte fertilization during in vitro fertilization

“…Elevated follicular fluid levels of inhibin B and estradiol have been reported to be associated with ovarian response, high quality of oocytes, and high fertilization and pregnancy rates (22)(23)(24), but the reverse also has been reported by some studies (15,23,25). In our study, the follicular fluid levels of inhibin B, estradiol, and progesterone were not statistically significantly different in the fertilized group and the nonfertilized group.…”

Alterations in Glucose Metabolism During Menstrual Cycle in Women With IDDM

“…Total glycosylated hemoglobin was measured by agar gel electrophoresis with removal of the labile component with the GLYTRAC glycosylated hemoglobin kit (Coming, Palo Alto, CA) (17). LH, FSH, estradiol, progesterone, and prolactin levels were determined by radioimmunoassay (18)(19)(20). Serum testosterone, dihydrotestosterone, and androstenedione were extracted from serum with ether and separated by celite chromatography before assay with specific single-antibody radioimmunoassays (21).…”
