Incremental Clomiphene Citrate Doses in Successive Cycles and FSH, LH and Steroid Hormone Levels

In the Bagcilar Research and Training Hospital Obstetrics and Gynecology department outpatient clinic for infertility, the basal gonadotropin and androgen levels are routinely measured. In unexplained infertility couples with normal ovarian reserves the first line drug used for ovulation induction is CC. The starting dose is 50mg/day and the treatment is started within the 2nd to the 5th days of the menstrual cycle and continued for 5 days. Starting on the 2nd-3rd day following the last dose of the drug, the follicular growth was monitored with the transvaginal ultrasound and blood levels of hormones including FSH, LH, estradiol, progesterone, androstenedione, testosterone, and dehydroepiandrosterone sulphate were measured every 2-3 days. In this follow-up, if no follicular growth was observed day21 of the cycle, the CC dose was increased to CC 100mg/day (2X1, 50mg). If follicular growth and ovulation is achieved with no concluding conception, the same dose of CC is used in the following 2-3 cycles. When a maximum number of 2 dominant follicles are obtained ovulation is triggered with recombinant human chorionic gonadotropin (rhCG) and timed coit or intrauterine insemination is conducted.
