Birth Control Methods01:22

Birth Control Methods

5.6K
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...

Intrauterine Drug Delivery Systems01:21

Intrauterine Drug Delivery Systems

169
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...

Development of the Sexual Organs in the Embryo and Fetus01:15

Development of the Sexual Organs in the Embryo and Fetus

5.6K
Development of the reproductive organs in an embryo starts from a bipotential state. This means the early embryo can develop either male or female reproductive organs. The formation of these organs begins with the growth of gonadal ridges that arise from the intermediate mesoderm during the fifth week of development.
Near the gonadal ridges, two duct systems are present: the mesonephric ducts (Wolffian ducts) and paramesonephric ducts (Müllerian ducts). These ducts form the basis for the...

Gonadal and Placental Hormones01:24

Gonadal and Placental Hormones

3.9K
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...

Hormonal Control of the Ovarian Cycle01:30

Hormonal Control of the Ovarian Cycle

5.2K
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...

Development of the Oral Microbiota01:28

Development of the Oral Microbiota

73
The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...

Summary

Recent advances in hormonal contraceptives offer women more choices, including long-acting methods and over-the-counter emergency options. However, clinician education remains key to improving access and women's fertility control.

Area of Science:

  • Reproductive Health
  • Contraception Science

Background:

  • Despite expanded contraceptive options, limited clinician knowledge restricts women's access to fertility control methods.
  • Informed choices are crucial for effective family planning and reproductive autonomy.

Purpose of the Study:

  • To assess recent advancements and ongoing debates in contraceptive methods.
  • To propose strategies for enhancing the availability and uptake of contraception.

Main Methods:

  • Review of novel hormonal contraceptive formulations, including alternative oestrogens and improved progestogens.
  • Analysis of new delivery systems for long-acting reversible contraceptives (LARCs).
  • Examination of the accessibility of emergency contraceptive methods.

Main Results:

  • Development of hormonal contraceptives utilizing oestradiol and advanced progestogens.
  • Introduction of user-friendly, long-acting contraceptive methods reducing failure rates.
  • Increased availability of over-the-counter emergency contraception.

Conclusions:

  • Significant progress in female contraception contrasts with the lack of male contraceptive options.
  • Improved clinician education and awareness are vital for maximizing the benefits of modern contraceptive technologies.
  • Further research and policy changes are needed to ensure equitable access to all contraceptive methods.
