The natural gonadotropin-releasing hormone ( GnRH ) is apt to be degraded by the peptidascs. In addition, the low level of GnRH in the peripheral circulation makes it diffucult to measure.
Suspensions of luteal cells were obtained from human corpora lutea in mid-luteal phase (day 19-23) by enzymatic dispersion.
