What male contraceptive methods are there?

[ad_1]

Contraceptive methods are very important tools to guarantee the right to sexual autonomy, in addition to helping to plan or control births.

A fairly common mistake is to consider that this responsibility falls exclusively on women, since there are also male contraceptive methods. Let’s review them.

Contraceptive or contraceptive methods are those that prevent or reduce the possibility of fertilization or pregnancy in sexual intercourse. They contribute to birth control, as well as reducing unwanted or teenage pregnancies.

Since 1960 the options for women have multiplied, currently having a dozen contraceptive methods, among which are:

  • Vaginal rings
  • Condoms
  • Diaphragms
  • Intrauterine devices (IUD).
  • Sterilization.
  • Implants
  • Injections
  • Patches
  • Pills

Male contraceptives

The options for men have not changed much. The oldest are abstinence or coitus interruptus (that is, withdrawing the penis before ejaculating, expelling the semen out of the vagina).

The latter is still one of the most practiced today, although experts say that it is not effective as believed.

  • What you need to know about the birth control pill

This is because ejaculating near the vagina runs the risk of pregnancy. In addition, the pre-ejaculatory fluid also contains sperm capable of fertilization.

Other male contraceptive methods are:

Condom or condom

This contraceptive method is one of the most used by men and women, since it not only prevents pregnancy, it also protects against many sexually transmitted diseases, such as genital herpes, syphilis, HIV or HPV.

The effectiveness of the condom as a contraceptive method can vary depending on its correct use or its quality (they are usually made with rubber or polyurethane latex).

How to use a condom?

You should place the condom on the head of the penis, with the ring rolled in the opposite direction to it. Pressing the tip, unwind it over the shaft of the penis until it reaches the base.

Using petroleum jelly, lotions, or oils can weaken the condom and lead to possible breakage.

At the end of sexual intercourse, hold the condom from the base while you carefully remove it, and then throw it away. Remember, a condom cannot be used twice.

Vasectomy

Vasectomy is a procedure that causes infertility in men by preventing sperm from reaching the testicles.

A small incision is made in the scrotum and each vas deferens is removed, cut, and ligated to prevent sperm from being released in ejaculation. Then they go back into the scrotum.

Although this practice is usually done with a scalpel, a method called no-scalpel vasectomy recently approved by the American Urological Association.

It is less invasive, simpler and faster to recover, since specific instruments are used for its execution, such as a clamp that causes the skin to open, separating and not cutting the fibers.

It is commonly believed that with vasectomy ejaculation is lost, which is false, since semen is produced in the seminal vesicle and not in the testicles, which is where sperm are produced.

Sperm represents only 3% of ejaculation and the other 97% is made up of various fluids from the prostate.
It is also not true that sexual desire or libido drops, or that it is a major surgery that takes a long time.

Although it is a potentially reversible method, surgery is required for this, so it is usually recommended for those men who have already formed a family and are not looking to have more children.

Reversible sperm inhibition under guidance

The reversible inhibition of sperm under guidance (RISUG) uses a polymer, a gel species, made up of two compounds: styrene maleic anhydride (SMA) dissolved in dimethyl sulfoxide (DMSO).

It is given by injection into the vas deferens and works by blocking and destroying the sperm by lowering the pH and creating charge disturbances.

The great advantage in relation to vasectomy is that they are more likely to be reversible, although specialists are still investigating their effects.

This contraceptive method was developed by the Indian Institute of Technology Kharagpur and patented in Bangladesh, China, USA and India under the trade name of Vasalgel.

Other contraceptives

Many surveys agree that more than half of men would be willing to use new contraceptives, preferably long-acting, reversible and non-hormonal.

In addition to those already mentioned, the researchers are working on the male contraceptive pill, called 11-beta-methyl-19-nortestosterone dodecylcarbonate, or 11-beta-MNTDC.

It is a modified testosterone that combines actions of a male hormone (androgen) and a progesterone. With this, it seeks to reduce sperm production and motility, temporarily affecting the fertility of men.

Another work around improving or suppressing male fertility is that of the University of California, which studied the process of hyperactivation.

This is the extra “push” or “force” that sperm need to break through the defenses of the egg.

As the researchers explained, sperm inhale progesterone, a hormone secreted by the ovum, which, by binding to an enzyme called ABHD2, provides the final boost the sperm needs to “finish its run.”

The evidence is preliminary, but experts believe that these findings could be used to develop a method of inactivating these interactions, with the aim of developing a new contraceptive method.

However, both for the male contraceptive pill and for the inhibition of sperm interactions, more studies are necessary to allow us to get out of the experimentation stages and to put this knowledge into practice.

To remind:

Although contraception often falls exclusively on women, it is also a men’s responsibility.

The availability of contraceptive methods is not as wide as that available to women, highlighting the use of condoms or vasectomy.

Male pills are also in the experimental stage, as well as polymers that seek to block and destroy sperm.

To avoid unplanned pregnancies, it is important to inform yourself, consult a health professional and thus find the best treatment.
