| dc.description | One of the main endocrinological disturbances in patients with polycystic ovarian syndrome (PCOS) is the increased baseline concentrations of luteinizing hormone (LH) and consequently a high LHrfollicle-stimulating hormone (FSH) ratio. The aim of this study was to assess the relationship between the baseline LH:FSH ratio with the stimulation response and the miscarriage risk in PCOS women stimulated for assisted reproduction techniques (ART) with and without gonadotrophin-releasing hormone analogue (GnRHa). Two groups of PCOS patients were analysed retrospectively. Group A (n = 20, 20 cycles) consisted of women stimulated with human menopausal gonadotrophin (HMG), and group B (n = 128, 162 cycles) comprised women stimulated with buserelin-long/HMG. LH and FSH concentrations were measured during the early follicular phase (days 4–6) in a preceding spontaneous or progestininduced cycle. The following parameters were assessed: number of follicles developed, number of oocytes obtained and percentage of mature oocytes, as well as number of abortions and live births. In group A, the baseline LH:FSH ratio was correlated inversely with the number of follicles developed (P < 0.05), the number of oocytes obtained (P < 0.05) and the percentage of mature oocytes (P < 0.05). In group B, no correlation was found between the LH:FSH ratio and the number of follicles and oocytes, because their numbers were relatively constant irrespective of the baseline LH:FSH ratio, but a significant inverse correlation was noted with the percentage of mature oocytes (P < 0.001). However, a comparison of the slopes of the curve indicated a better correlation between the LH:FSH ratio and the percentage of mature oocytes in group A than in group B (P < 0.05). These findings were also confirmed when patients were subdivided according to the LH:FSH ratio (<3 or 3=3). Furthermore, in women who miscarried, the mean LH:FSH ratio was significantly higher than in women having a live birth. In conclusion, in PCOS patients stimulated with HMG, a high basal LH:FSH ratio appears to have an adverse effect on the number of follicles and oocytes, as well as on oocyte maturity. On the other hand, the administration of GnRHa in the long protocol seems to reverse this detrimental effect on follicle and oocyte development. Furthermore, a higher LH:FSH ratio seems to predict a greater possibility for miscarriage, despite the use of GnRHa. |
