Testosterone: Functions and Regulation01:26

Testosterone: Functions and Regulation

588
The intricate hormonal interplay essential for male reproductive health begins with the release of gonadotropin-releasing hormone (GnRH) by the hypothalamus. This hormone prompts the pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). LH targets the Leydig cells in the testes, stimulating them to produce and release testosterone. In concert with testosterone, FSH acts on the Sertoli cells within the seminiferous tubules to facilitate the release of...

Birth Control Methods

215
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...

Infertility in Males01:23

Infertility in Males

256
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...

Spermatogenesis01:41

Spermatogenesis

102.3K
Spermatogenesis is the process by which haploid sperm cells are produced in the male testes. It starts with stem cells located close to the outer rim of seminiferous tubules. These spermatogonial stem cells divide asymmetrically to give rise to additional stem cells (meaning that these structures “self-renew”), as well as sperm progenitors, called spermatocytes. Importantly, this method of asymmetric mitotic division maintains a population of spermatogonial stem cells in the male...

Menopause01:28

Menopause

146
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...

Gonadal and Placental Hormones01:24

Gonadal and Placental Hormones

1.4K
The gonads, namely the testes in males and the ovaries in females, are pivotal in producing gonadal hormones that orchestrate the intricate processes of sexual development and reproduction.
In males, testosterone is the primary gonadal androgen. It plays a central role in the maturation of male reproductive organs — the penis and testes. Additionally, testosterone is instrumental in the development of secondary sexual characteristics — a deep voice as well as facial and pubic hair...

Area of Science:

  • Reproductive Endocrinology
  • Pharmacology of Contraception
  • Men's Health

Background:

  • Unintended pregnancy rates remain high despite numerous female contraceptive methods.
  • Recent abortion restrictions highlight the need for expanded contraceptive options.
  • There is increasing interest from men in utilizing novel reversible male contraceptives.

Purpose of the Study:

  • To review the current status and future prospects of hormonal male contraception.
  • To assess the potential of novel male contraceptive formulations.
  • To address the growing demand for male birth control methods.

Main Methods:

  • Review of clinical research and drug development in male contraception.
  • Analysis of hormonal mechanisms, including androgen and androgen-progestin combinations.
  • Evaluation of the hypothalamic-pituitary-testicular axis regulation by contraceptive agents.

Main Results:

  • No reversible hormonal male contraceptive product is currently available despite decades of research.
  • Nestorone/testosterone and other novel androgens show promise for Phase 3 studies and market entry.
  • Progestin addition to androgens enhances sperm suppression while androgens maintain eugonadism.

Conclusions:

  • Hormonal male contraception effectively suppresses spermatogenesis via negative feedback on the hypothalamic-pituitary-testicular axis.
  • There is a significant and growing demand and acceptance for male contraceptive options.
  • Advancing male contraceptives requires regulatory oversight, clear safety/efficacy standards, and industry support.
