The most used male contraceptive methods are vasectomy and condoms, which prevent the sperm from reaching the egg and generating a pregnancy.

Condoms are the most popular method, as they are more practical, reversible, effective and also provide protection against sexually transmitted diseases. Vasectomy, on the other hand, is a type of contraceptive with a definitive effect, since the doctor cuts the channel that carries sperm from the testicle to the penis, and this procedure is performed by men who no longer intend to have children.

In recent years, several researches have been carried out with the objective of creating a reversible contraceptive that is similar to the female contraceptive pill, giving men more options.Among the main male contraceptives that are under development, the contraceptive gel and the male pill, which act by decreasing sperm production and motility, despite having reversible effects.

1. Condom

Condoms, popularly called condoms, are the most used contraceptive method by both men and women, because in addition to preventing pregnancy, they also protect against sexually transmitted diseases.

In addition, it does not cause any hormonal changes, nor does it alter the process of sperm production and release, being completely reversible.

See how to put the condom on correctly.

2. Vasectomy

Vasectomy is a male contraceptive method that consists of cutting the canal that connects the testicle to the penis and carries sperm.Thus, there is no release of sperm during ejaculation and, consequently, fertilization cannot occur, preventing pregnancy.

This contraceptive method is normally used by men who do not wish to have more children, since, in most cases, it is irreversible. See how a vasectomy is performed and how it works.

3. Contraceptive gel

The contraceptive gel, known as Vasalgel, is a non-hormonal option, which is applied in the genital region, specifically in the vas deferens, which are the channels that carry sperm from the testes to the penis, and acts by blocking the passage of sperm for up to 10 years.

This procedure lasts about 15 minutes, is done under local anesthesia and it is possible to reverse the effect of this gel by applying a solvent to the place where the gel was placed.

The gel does not prevent ejaculation, only the passage of sperm. Vasalgel has no contraindications nor does it modify the production of male hormones, but more studies are still needed.

4. Male contraceptive pill

The male contraceptive pill, also called Dimethandrolone Undecanoate or DMAU, is a pill consisting of derivatives of female hormones that acts by decreasing the amount of testosterone, which reduces sperm production and motility, interfering with the male fertility temporarily.

Although it has already been tested on some men, the male birth control pill is not yet available due to reported side effects such as decreased libido, mood swings and increased acne, for example.

5. Contraceptive injection

Recently, an injection called RISUG was developed, composed of substances called polymers and is applied in the channel through which the spermatozoa pass, under local anesthesia. This injection blocks ejaculation, preventing the exit of sperm during the sexual act, and the action of the drug lasts between 10 to 15 years.

If the man wants to reverse the action of the injection, another drug that releases sperm can be applied. However, although the male contraceptive injection has already been tested, it is still in the process of being approved by government institutions responsible for releasing new drugs.

6. Retinoic acid inhibitors (DBAD)

Retinoic acid, which is present in vitamin A, has been shown to have an effect on male fertility, because a study indicated that the inhibition of a certain compound has an effect on the enzyme that synthesizes retinoid acid, causing a decrease in production of sperm, thus preventing an unwanted pregnancy.

However, this method also influences alcohol metabolism, so studies in animal and human models had to be interrupted in order to better evaluate the contraceptive effect of this method, in order to avoid interactions with this and other possible substances.

7. H2-Gamendazol

The contraceptive H2-Gamendazole interferes with the process of sperm formation and differentiation. The use of this method has been shown to be reversible at low doses, however, higher doses may have an irreversible effect and, therefore, more studies in animals are needed to determine the safe dose and, thus, be possible to carry out tests in humans with the goal of making H2-Gamendazole a non-permanent contraceptive.
