Abstract
OBJECTIVE
To determine if cultured human granulosa cells (GCs) obtained from women at risk for ovarian hyperstimulation syndrome (OHSS) possess altered steroidogenic capacity.
DESIGN
Prospective analysis of 28 consecutive in vitro fertilization-gamete intrafallopian transfer (IVF-GIFT) cycles.
SETTING
In Vitro Fertilization Program at Rush Presbyterian St. Luke's Medical Center in Chicago, Illinois.
PATIENTS
Eighteen patients (group I) with serum estradiol (E2) levels > 7,342 pmol/L on the day of exogenous human chorionic gonadotropin (hCG) administration (day 0) with > 10 ovarian follicles present (high risk for OHSS); 10 patients (group II) with E2 < or = 7,342 pmol/L on day 0 and < or = 10 follicles.
INTERVENTIONS
Human GCs obtained during gonadotropin-releasing hormone agonist-pretreated IVF-GIFT cycles were cultured in the absence (control) or presence (hCG) of hCG, 1 IU/mL, and/or androstenedione (A) 10(-7) M. Granulosa cells obtained from follicles < or = 15 mm diameter were cultured separately from those obtained from follicles > 15 mm diameter.
MAIN OUTCOME MEASURES
Estradiol (E2) and progesterone were measured in tissue-culture medium by a solid-phase direct radioimmunoassay.
RESULTS
In vitro E2 production by cultured GCs was significantly increased in follicles < or = 15 mm diameter from women considered at risk of developing OHSS (group I). Estradiol response to hCG and/or A appeared enhanced in all follicles in group I. Progesterone production in the basal and hCG challenged state was greater in cells obtained from large follicles in group I than in group II.
CONCLUSION
Ovarian hyperstimulation syndrome appears to be a function of an increased number of follicles that express an enhanced steroidogenic capacity.
