Prognostic value of pre-ovulatory serum progesterone, LH and oestradiol-17 beta levels in stimulated cycles for in-vitro fertilization.
The prognostic value of a decrease in oestradiol-17 beta (E2) on the day after HCG injection in stimulated cycles has been related to a premature increase in plasma progesterone (P) on the day before HCG injection. This retrospective study was carried out on 363 patients who were divided into four groups. Patients in group A were given clomiphene citrate plus human menopausal gonadotrophin (HMG) to stimulate follicle growth, and they were subdivided into subgroups A1 and A2 who showed an increase or a decrease in E2 levels after HCG injection. The changes in E2 were greater than 10% of the levels on the previous day. Patients in group B were stimulated by HMG and were similarly subdivided into subgroups B1 and B2 according to their E2 levels. The number of oocytes recovered and the incidence of pregnancy was significantly higher in A2 as compared with A1, and higher but not significantly so in B2 versus B1. Moreover, in subgroups A1 and B1 the day before the decrease of E2 was marked by a significant rise in LH before the HCG injection. We suggest that oocyte recovery is deferred in these cases.
