Overview

Objective:
Ovarian Hyperstimulation Syndrome (OHSS) is a severe health complication observed in some patients undergoing hormonal stimulation during IVF. Some authors [17] present that OHSS is associated with Polycystic Ovary (PCO) and with a high count of growing follicles (more than 18) responding to FSH hyperstimulation, although none of them is sufficient to predict the onset of OHSS. The aim of this study is to analyze the association between PCOS and OHSS the Inhibin B-based TFF/SBM index [13].

Design:
Retrospective analysis.

Setting:
Assisted Reproduction Center, Department of Obstetrics and Gynecology, 1st Faculty of Medicine, Charles University and General Faculty Hospital in Prague, Sigma-Aldrich, Prague, Immunotech, a.s., Prague.

Methods:
Serum and follicular fluid of 36 women (high responders with more than 18 growing follicles) in IVF program were collected at the day of oocyte pick up and used for analysis of Inhibin B. Age: mean 30.2 years (24–35 years, median 31.0 years ), BMI: mean 22.34 (18.3–29.7, median 21.6). For every patient, the TFF/SBM index was calculated as follows: [concentration in FF] x [growing follicle count]/ [concentration in serum] x [body mass]. A distribution of the following parameters were compared: OHSS status, TFF/SBM index based on Inhibin B, growing follicle count and the incidence of PCOS.

Results:
Values of the TFF/SBM index showed an association with the severe form of OHSS but not with the incidence of PCOS.

Conclusion:
These observations suggested that the incidence of PCOS is not associated with the development of severe form of OHSS, but may be still associated with a high count of growing follicles.

Key words:
OHSS, PCOS, inhibin B, IVF, follicular fluid, serum.
