Contraception in perimenopause

Menopause (New York, N.Y.)
|April 25, 2025
Summary
Women in perimenopause can still get pregnant, facing higher risks. Effective contraception is crucial until menopause is confirmed to prevent unintended pregnancies and complications.
Area of Science:
- Reproductive Endocrinology
- Women's Health
Background:
- Perimenopause involves hormonal fluctuations and irregular cycles, preceding menopause.
- Fertility declines during this transition, but pregnancy is still possible.
Purpose of the Study:
- To highlight the risk of unintended pregnancies during perimenopause.
- To emphasize the importance of counseling and contraception for perimenopausal women.
Main Methods:
- Review of hormonal changes and fertility status during perimenopause.
- Assessment of contraceptive options suitable for perimenopausal women.
Main Results:
- Unintended pregnancies in perimenopause carry increased risks for poor outcomes.
- Numerous effective hormonal and nonhormonal contraceptive methods are available.
Conclusions:
- Adequate counseling on contraception is essential for all women in perimenopause.
- Contraception should be continued until menopause is definitively confirmed.

Vasectomy is a surgical form of male sterilization that involves severing and sealing the vasa deferentia, preventing sperm from mixing with semen during ejaculation. Because a vasectomy does not impact the testes' ability to produce testosterone, hormone levels, libido, and sexual function generally remain unchanged. While vasectomy is highly effective in preventing pregnancy, with a success rate near 99.85%, rare cases of recanalization (spontaneous reconnection) can occur. Although...

Menopause, a natural biological process marking the end of a woman's fertility, typically occurs between the fifth and sixth decade of life. This phase is characterized by the exhaustion of the ovarian follicle pool, leading to less responsive ovaries despite the high levels of Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH). The consequential decrease in estrogen production results in symptoms like hot flashes, heavy sweating, headaches, hair loss, muscle pains, vaginal...

01:22Hormonal Regulation of the Menstrual Cycle
195
The ovarian cycle regulates endometrial changes throughout a single menstrual cycle via the coordinated action of gonadotrophin-releasing hormone (GnRH) and gonadotrophins.
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH...

The ovarian cycle is meticulously regulated by the hypothalamic-pituitary-gonadal axis. This cycle orchestrates the release of a mature oocyte, essential for reproduction.
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...

Hormones regulate a significant portion of digestion through activation of the neuroendocrine system. The neuroendocrine system of digestion contains many different hormones all with multiple functions that are both, directly and indirectly, involved in digestion.

The menstrual cycle includes a critical component known as the ovarian cycle, which undergoes two main phases each month—the follicular phase and the luteal phase. The follicular phase is variable and averaging around 14 days. Ovulation, triggered by a surge in luteinizing hormone (LH), marks the transition between the two phases. The second phase, the luteal phase, is relatively consistent, lasting approximately 14 days, and is marked by the activity of the corpus luteum. While a cycle...
