Hormonal male contraception shows promise by suppressing sperm production, but faces significant biological, practical, and financial hurdles. Overcoming these challenges could lead to a breakthrough in male birth control options.
Area of Science:
- Reproductive endocrinology
- Male reproductive health
- Contraceptive development
Background:
- Limited options exist for male contraception.
- Hormonal methods targeting spermatogenesis are most promising.
- Public and expert opinions on male contraception are divided.
Purpose of the Study:
- To review the principles of hormonal male contraception.
- To discuss the results of recent clinical trials.
- To explore future perspectives in the field.
Main Methods:
- Review of hormonal strategies for male contraception.
- Analysis of clinical trial data for testosterone and progestin combinations.
- Discussion of biological, practical, and economic challenges.
Main Results:
- Hormonal methods aim to suppress gonadotropin secretion, reducing testicular androgen production and spermatogenesis.
- Testosterone and progestin combinations are the most promising leads.
- Significant obstacles remain regarding efficacy, side effects, reversibility, cost, and cultural acceptance.
Conclusions:
- Despite challenges, hormonal male contraception has the potential for near-term breakthrough.
- Lack of pharmaceutical industry involvement and funding hinders progress.
- Modest investment could accelerate the availability of male hormonal contraceptives.

Hormonal Regulation of the Menstrual Cycle
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 release.

The Menstrual Cycle
The menstrual phase occurs from days 1 to 5 and involves the shedding of the stratum functionalis, as a uterine...
Hormonal Control of the Ovarian Cycle
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...
