Summary
New male hormonal contraceptives are needed. Combining testosterone with other agents effectively suppresses sperm production, offering a reversible and effective option for men.
Area of Science:
- Reproductive endocrinology
- Contraceptive development
- Male reproductive health
Background:
- Current male contraceptive options are limited in effectiveness and reversibility.
- Surveys show willingness among men and partners for male hormonal contraceptives.
- Male hormonal contraception reversibly suppresses sperm production.
Purpose of the Study:
- To review recent advancements in male hormonal contraceptive development.
- To highlight the efficacy of testosterone combined with progestins or GnRH antagonists.
- To discuss the specific susceptibility of Asian men to testosterone-based suppression.
Main Methods:
- Review of recent scientific literature on male hormonal contraception.
- Analysis of studies combining testosterone with progestins or gonadotropin-releasing hormone antagonists.
- Examination of data on sperm suppression and reversibility.
Main Results:
- Testosterone combined with progestins or GnRH antagonists induces profound and consistent sperm suppression.
- Asian men show increased susceptibility to testosterone's suppressive effects.
- Adjunctive agents may be necessary for optimal contraceptive protection in some populations.
Conclusions:
- Male hormonal contraceptives combining testosterone with other agents show promise.
- Further research is needed to optimize efficacy and reversibility for diverse populations.
- Targeted approaches may be required, considering ethnic variations in response.

01:22Birth Control Methods
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 vasectomy...
01:21Intrauterine Drug Delivery Systems
Controlled-release systems for intravaginal and intrauterine drug delivery have been developed primarily for the administration of contraceptive steroid hormones. These delivery routes circumvent first-pass hepatic metabolism, thereby enhancing bioavailability and allowing for reduced systemic dosages compared to oral administration. Such approaches contribute to improved therapeutic efficacy and patient compliance, particularly in long-term contraceptive regimens.Intravaginal Drug Delivery...
01:23Infertility in Males
Male infertility affects millions of couples worldwide, arising from various factors that impact different stages of the reproductive process. An endocrine imbalance resulting from conditions like hypogonadism, Klinefelter syndrome, or pituitary disorders can disrupt hormone levels and reduce sperm production. Testicular defects, such as tumors, cryptorchidism, atrophic testes, abnormal sperm morphology, and low sperm count or motility, may arise due to genetic factors, structural...
01:22Hormonal Regulation of the Menstrual Cycle
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 release.

01:40Hormonal Regulation
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.
01:31Adrenergic Antagonists: ɑ and β-Receptor Blockers
Third-generation β-blockers, such as labetalol and carvedilol, represent a significant advancement in managing cardiovascular conditions. Unlike conventional β-blockers, which can induce peripheral vasoconstriction, third-generation drugs block α1 adrenoceptors. This promotes vasodilation through several mechanisms, such as increased nitric oxide production, inhibition of calcium ion entry, opening of potassium ion channels, and antioxidant action. Labetalol, for instance, is clinically...
