Birth Control Methods01:22

Birth Control Methods

7.3K
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

682
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...

Intrauterine Drug Delivery Systems01:21

Intrauterine Drug Delivery Systems

127
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...

Hormonal Regulation of the Menstrual Cycle01:22

Hormonal Regulation of the Menstrual Cycle

2.3K
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...

Infertility in Females01:28

Infertility in Females

5.0K
Female infertility is defined as the inability to conceive after a year of regular, unprotected intercourse and affects about 10–15% of couples worldwide. The primary cause of female infertility is ovulatory disorders, which hinder the release of eggs. These disorders can be classified as hypothalamic amenorrhea, polycystic ovarian syndrome (PCOS), premature ovarian failure, and hyperprolactinemic anovulation disorders.
Endometriosis, a condition characterized by abnormal growth of...

Gonadal and Placental Hormones01:24

Gonadal and Placental Hormones

3.8K
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...

Summary
This summary is machine-generated.

Despite available female options, many pregnancies remain undesired. Current male contraceptive methods (MCMs) have limitations, driving research for safer, more effective hormonal and non-hormonal male contraceptives.

Area of Science:

  • Reproductive Health
  • Pharmacology
  • Urology

Background:

  • High rates of unintended pregnancies persist despite numerous female contraceptive methods.
  • A significant percentage of men desire equal participation in family planning, yet male contraceptive methods (MCMs) are underutilized globally.
  • Existing MCMs like condoms have high failure rates, and vasectomy is poorly reversible.

Purpose of the Study:

  • To review the current landscape and challenges of male contraceptive methods (MCMs).
  • To explore the development and limitations of male hormonal contraceptives (MHCs).
  • To discuss the potential and hurdles of non-hormonal MCMs.

Main Methods:

  • Review of existing literature on male contraceptive methods.
  • Analysis of clinical trial data for hormonal and non-hormonal MCMs.
  • Evaluation of safety, efficacy, and practicality concerns for different MCM approaches.

Main Results:

  • Male hormonal contraceptives (MHCs) have shown efficacy (Pearl Index <1.0) but face issues with variable response rates, administration methods, and potential long-term side effects.
  • Non-hormonal MCMs show theoretical promise for specificity but have limited clinical trial data and some have been abandoned due to toxicity.
  • Current MCMs do not meet the need for a reliable, safe, and practical option, leaving the burden of contraception primarily on women.

Conclusions:

  • The development of effective male contraceptives is crucial for equitable family planning.
  • Significant challenges remain in developing safe, reversible, and practical pharmaceutical MCMs.
  • Further research into both hormonal and non-hormonal MCMs is needed to address the unmet need.
