Various Methods of Contraception: Exploring Pills, Devices, Injections, and Long-Term Solutions
In the ongoing quest for effective and safe contraceptive methods, researchers and medical professionals continue to explore various options for both men and women. Here's a breakdown of some of the most common contraceptives available, as well as those currently in development.
For women, emergency contraception is often viewed as a kind of abortion, but it's essential to understand that it acts before the egg is implanted in the uterus. Emergency contraceptive pills, commonly known as the morning-after pill, can prevent pregnancy after intercourse, with Ella being up to 85% effective and Plan B being 75% to 89% effective.
Other methods include hormonal IUDs, which prevent pregnancy by thickening the cervical mucus and thinning the uterus wall, lasting for 3, 8, or 10 years. The contraceptive vaginal ring, a flexible, plastic ring that releases a low dose of progestin and estrogen over 3 weeks, is another option.
The female condom, made of polyurethane, has a flexible ring at each end, one fixing behind the pubic bone to hold the condom in place, while the other ring stays outside the vagina. It is 79% effective. The diaphragm, a rubber, dome-shaped device inserted into the vagina and placed over the cervix, used with spermicide, is 88% effective.
Natural family planning and fertility awareness involve being familiar with the signs and symptoms of ovulation, the pattern of the menstrual cycle, and planning sexual activity to avoid pregnancy. This method is about 78% to 98% effective.
In the realm of male contraceptives, hormonal methods are likely to be the first to hit the market within the next 5–6 years. These work by administering external androgens and progestogens to suppress gonadotropins LH and FSH, reducing sperm production within 4–12 weeks. Examples in clinical trials include NES/T (Nesterone/Testosterone) gel, DMAU (Dimethandrolone undecanoate), and 11β-MNTDC.
Non-hormonal options are also being developed, aiming to inhibit sperm production or function through mechanisms other than hormonal suppression. Examples include YCT-529, a retinoic-acid receptor alpha inhibitor, and a soluble adenylyl cyclase (sAc) inhibitor pill.
Vasectomy, a long-established, highly effective male contraceptive option with over 99% effectiveness, remains the most reliable and low-risk method currently in use. It is considered safer than long-term hormonal contraception for females but is generally permanent, though reversals are sometimes possible.
It's worth noting that condoms, made of polyurethane or latex, are also an effective contraceptive method for both men and women, with a success rate of around 87%. They not only prevent pregnancy but also help protect against sexually transmitted infections (STIs).
The combined contraceptive pill, taken daily and containing two hormones, estrogen and progestin, prevents the release of the egg. The contraceptive injection, or the shot, is a progestin-only birth control drug injected every 3 months at a doctor's office. The implant, a rod with a core of progestin inserted under the skin of the upper arm, is effective for up to 5 years.
In conclusion, the variety of contraceptive options available offers individuals a wide range of choices to suit their specific needs and lifestyles. It's crucial to consult with a healthcare professional to determine the most suitable method for each individual.
- Pfizer, a science-based pharmaceutical company, is currently developing a male contraceptive that suppresses gonadotropins LH and FSH, reducing sperm production, with examples such as NES/T (Nesterone/Testosterone) gel and DMAU (Dimethandrolone undecundioate) in clinical trials.
- Hormonal IUDs used by women prevent pregnancy by thickening the cervical mucus and thinning the uterus wall, lasting for 3, 8, or 10 years, and are considered as one of the common contraceptives available.
- In the health-and-wellness sector, a gynecological issue like pregnancy can be blocked with emergency contraceptive pills, such as Plan B and Ella, which are up to 85% and 75% to 89% effective, respectively, in preventing pregnancy after intercourse.
- Alongside the female condom, women's health also benefits from natural family planning and fertility awareness, where the knowledge of ovulation patterns helps in planning sexual activity to avoid unwanted pregnancies, with an effectiveness rate of 78% to 98%.
- In the realm of women's health, there exists a method called the contraceptive vaginal ring, which releases a low dose of progestin and estrogen over 3 weeks and serves as another effective contraceptive option.
