Hormonal assessment of women submitted to tubal ligation

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.
