The role of inhibin B as a basal determinant of ovarian reserve.

Our objective was to compare inhibin B and conventional basal determinants in designating the ovarian reserve in patients receiving assisted reproductive treatment. A total of 58 women, aged 19-47 years, who were accepted for assisted reproductive treatment at the Zeynep Kamil Women and Children's Hospital, Department of Assisted Reproductive Technologies, were included in the study. The age, body mass index, basal levels of follicle stimulating hormone, estradiol and inhibin B, volume of the ovary and number of antral follicles were compared prospectively. When the number of oocytes collected was > or = 5, this was accepted as a sufficient ovarian response. Serum inhibin B (cut-off level 56 pg/ml), as a basal determinant of ovarian reserve, had the highest sensitivity (81%) and specificity (81%). The usefulness of serum inhibin B measurement as a basal determinant of ovarian reserve is supported.

Unicornuate uterus and unilateral ovarian agenesis associated with pelvic kidney.

In this report, we present a case of unilateral müllerian and ovarian agenesis associated with pelvic kidney. The patient was a 27-year-old woman who complained of an inability to conceive. We performed a hysterosalpingogram, hysteroscopy, laparoscopy, and an excretory urogram (IVP). At laparoscopy, we found an unicornuate uterus without a rudimentary horn. The right round ligament, fallopian tube, and ovary were present, but they were absent at the left side. Postoperative IVP revealed a pelvic kidney. Ultimately, her infertility was found to be due to a male factor: the abnormal semen of her partner. The couple was referred to our in vitro fertilization (IVF) unit. Because of the close embryologic association between the genital and urinary tracts, evaluation of the urinary tract in any patient with a genital or gonadal anomaly is necessary.
