title: Hormonal assessment of women submitted to tubal ligation.
abstract: Sixteen fertile women aged 30-35 years with regular menstruations were studied before and 6 months after tubal ligation (TL). The diagnosis of ovulation was based on clinical ultrasonographic and hormonal parameters [follicle-stimulating hormone (FSH), luteinizing hormone (LH), E2 and P4]. The menstrual pattern did not vary before and after surgery. Follicular or luteal phase FSH and E2 levels did not differ between the pre- and post-TL period. Luteinizing hormone levels on days -2 and 0 of the follicular phase were significantly higher during the post-TL period, while no difference was observed for the luteal phase. P4 levels during the follicular phase did not differ between the two periods, except for day -4, while they were lower during the post-TL luteal phase. The results of the study suggest that in the present patient group, no modifications in the menstrual pattern could be observed 6 months after TL, and TL appears not to interfere with ovulation. Luteinizing hormone levels showed an increase during the ovulatory period after TL, and progesterone secretion decreased during the post-TL luteal phase.
