Progestogens with or without oestrogen for irregular uterine bleeding associated with anovulation

Area of Science:

• Gynecology
• Reproductive Endocrinology

Background:

• Irregular menstrual bleeding is often linked to anovulation, particularly in women with conditions like polycystic ovary syndrome (PCOS).
• Prolonged estrogen stimulation without progesterone can lead to irregular, heavy bleeding.
• Hormonal therapies, including progestogens and combined estrogen-progestogen treatments, are used to manage these bleeding patterns.

Purpose of the Study:

• To evaluate the effectiveness and acceptability of progestogen-based therapies for irregular menstrual bleeding associated with oligo/anovulation.
• To assess treatments involving progestogens alone or in combination with estrogens.

Main Methods:

• A systematic search of multiple databases (Cochrane, MEDLINE, EMBASE, PsycINFO) was conducted in February 2012.
• Included were randomized controlled trials (RCTs) of progestogens (any route) or combined estrogen-progestogen treatments.
• Study quality assessment and data extraction were performed independently by two experts.

Main Results:

• No randomized trials were found comparing progestogens with placebo or combined estrogen-progestogen treatments for anovulatory bleeding.
• The identified literature did not provide comparative data on different progestogen regimens or dosages.

Conclusions:

• There is a significant lack of high-quality randomized studies on the use of progestogens and combined hormone therapy for anovulatory irregular menstrual bleeding.
• Current evidence does not support a consensus on the most effective hormonal regimens.
• Further research is essential to clarify the role of these treatments in managing this common gynecological issue.
