Ovarian histology and function after total abdominal hysterectomy.

Ovarian histology and function were assessed before and after total abdominal hysterectomy in 25 patients with symptomatic uterine myomata. Immediately before hysterectomy, bilateral ovarian biopsies were performed, and, 12 months later, all patients underwent a second ovarian biopsy through laparoscopy. Histologic study of the ovaries one year after total abdominal hysterectomy showed stromal cell hyperplasia, thickening of the tunica albuginea, and a significant decrease of follicular reserve, follicular cysts, and corpora albicantia. There was no significant difference in the number of atretic follicles and corpora lutea. The serum levels of all hormones studied were unchanged 12 months after the surgical procedures.
