[The secretion of the main ovarian steroids during bleeding in the premenopause]
Insights
Premenopausal dysfunctional bleeding is linked to low estradiol and progesterone, with high testosterone levels. Hormone secretion shows no clear pattern over three days, indicating significant individual variations.
Area of Science:
- Reproductive Endocrinology
- Gynecology
Background:
- Dysfunctional uterine bleeding (DUB) is a common gynecological issue.
- The premenopausal phase of climacteric is characterized by hormonal fluctuations.
Purpose of the Study:
- To investigate the secretion patterns of key ovarian steroids during premenopausal dysfunctional bleeding.
- To correlate hormone levels with the occurrence of dysfunctional bleeding in premenopausal women.
Main Methods:
- Study included 46 premenopausal women (mean age 47.02 years).
- Measured serum concentrations of estradiol, progesterone, and testosterone.
- Hormone levels were determined over three successive days.
Main Results:
- Premenopausal bleeding was associated with significantly lower estradiol levels (hypoestradiolemia).
- Progesterone levels were relatively lower (hypoprogesteronemia) compared to the early follicular phase.
- Testosterone levels were relatively high (testosteronemia) during bleeding episodes.
- No definite dynamics in ovarian steroid secretion were observed over the three-day period.
- Substantial individual variations in hormone secretion were noted.
Conclusions:
- Dysfunctional bleeding in premenopausal women is characterized by specific ovarian steroid profiles.
- The observed hormonal imbalances, particularly hypoestradiolemia and hypoprogesteronemia, may contribute to bleeding irregularities.
- Lack of clear secretory dynamics and significant individual differences highlight the complexity of premenopausal bleeding.
Abstract:
The authors study the secretion of the basic ovarian steroids (estradiol, progesterone and testosterone) during dysfunctional bleedings in 46 women at the premenopausal phase of climacteric (mean age of 47.02 years). The results show that the premenopausal bleeding occurs on the background of manifested hypoestradiolemia (2.5 times lower than that at the early follicular phase), hypoprogesteronemia (relatively higher that at the early follicular early follicular phase) and relatively high testosteronemia. Determination of the hormones during three successive days show lack of definite dynamics in the secretion of these ovarian steroids. Considerable individual differences are described.
