Summary

Ovarian testosterone secretion increases during the menopausal transition, with the highest levels observed in postmenopausal women. This increased ovarian vein testosterone is not reflected in peripheral blood levels.

Background:

Ovarian testosterone production is crucial for female physiology.
Understanding changes in ovarian hormone secretion during menopause is vital for women's health.

Purpose of the Study:

To investigate ovarian testosterone secretion in pre-, peri-, and postmenopausal women.
To correlate testosterone levels with age and ovarian stromal hyperplasia.

Main Methods:

Analysis of ovarian and peripheral venous testosterone levels in 52 women (aged 42-69).
Categorization of women into premenopausal, perimenopausal, and postmenopausal groups.
Measurement of estradiol, progesterone, gonadotropins, and assessment of ovarian stromal hyperplasia.

Main Results:

Related Experiment Videos

Ovarian vein steroid hormone levels were higher than peripheral levels.
A positive correlation was found between age and ovarian vein testosterone.
Increased testosterone secretion was significantly associated with ovarian stromal hyperplasia.

Conclusions:

The ovary appears to increase testosterone secretion during the menopausal transition.
Postmenopausal women exhibited the highest ovarian vein testosterone levels.
Elevated ovarian testosterone was not detected in peripheral circulation.
