Sir, We thank Drs El Hakim and Cahil for their interest and reaction to our paper (de Koning et al. 2008). It is true that the highest measured FSH level is the one that makes clinicians aware of the possible low ovarian reserve. It is known that a normal or moderately elevated FSH can still be found in women with low ovarian reserve due to variable FSH levels and possibly variable cohort size....

BACKGROUND Detection of best predictor of ovarian reserve in patients with temporarily or consistently elevated early follicular phase serum levels of FSH is one of the most important goals in assisted reproductive technique (ART). OBJECTIVE To evaluate whether high level of anti-mullerian hormone level is related to success of ART in patients with temporarily or consistently elevated early f...

To investigate the significance of changes in ovarian inhibin in gonadal dysfunction with persistent estrus, female rats with persistent estrus were studied as animal model for polycystic ovaries (PCO). Newborn female Wistar rats treated with testosterone propionate s. c. (TP) and female rats raised under continuous light (LL) started at 9 weeks of age entered into continuous estrus 5 and 2 or ...

OBJECTIVE To evaluate and compare IVF outcomes of patients within different age categories who had a normal basal FSH level with outcomes of patients with an elevated day 3 FSH level. DESIGN Retrospective analysis. SETTING Large, private IVF center. PATIENT(S) We analyzed 2,708 patients. Of these, 2,477 had normal basal FSH levels, and 231 had elevated basal FSH levels (> or =13.03 IU/L)....

OBJECTIVES A significant number of individuals have high serum follicle stimulating hormone (FSH) levels but do not meet the criteria for diagnosis of premature ovarian insufficiency (POI) due to ongoing menstruation. We compared a group of women with elevated FSH levels and POI with a control group in terms of biochemical markers. METHODS In this cross-sectional retrospective study, 38 POI c...

BACKGROUND Elevated early follicular phase (EFP) FSH is frequently observed in subfertile patients. In these women, temporary normalization of FSH concentrations is known to occur. We studied the complete endocrine cycle profile of subfertile young women with elevated basal FSH compared with controls. METHODS Daily bloodsampling and ultrasound monitoring in the follicular phase was performed in...
