To elucidate biochemical evidence for follicular and oocyte maturation, inhibin-A, inhibin-B and activin-A concentrations were measured in 200 follicular fluid samples from follicles ranging from 10.2mm to 36mm in diameter. Inhibin-A concentrations varied from 7.93-436 ng/ml with a mean value was 40.1ng/ml; Inhibin B concentrations varied from 9.7-786 ng/ml with a mean value of 187.3ng/ml; Activin A concentrations varied from 1.73-267.9 ng/ml with a mean value of 40.3ng/ml.

Background: Being little known about the biochemistry behind the follicular content or granulosa cells surrounding a mature oocyte in Assisted Reproductive Technology, our study set up to investigate the changes in steroid and cytokines' productions by cultured granulosa cells (GC) taken from individual follicles from women undergoing Controlled Ovarian Hyperstimulation (COH).MATERIALS AND METHODS: Granulosa cells isolated from 75 individual follicles we...
