What is male contraception?

Male contraception refers to any method specifically designed to allow men to prevent pregnancy temporarily or permanently. To date, traditional options have been limited to two alternatives:

1. The condom: Effective barrier method, but not always reliable due to possible breakage or misuse.
2. Vasectomy: An effective but invasive surgical procedure, with difficulty in reversing in some cases.

Challenges and Methodologies in Development

The development of male contraceptives presents unique challenges and innovative methodologies. The production and functionality of sperm It is a central aspect of this research, along with the need to ensure the safety of the new methods.

Sperm Production

Sperm production in men occurs continuously and is not limited to monthly cycles, adding complexity to the creation of effective contraceptives. Research has focused on different approaches to address this issue.

Suppression of spermatogenesis

One of the methods examined involves the suppression of spermatogenesis, i.e., sperm production is inhibited to reduce their number to levels that do not allow fertilization. This approach seeks to create a contraceptive that is reversible and does not affect other hormonal functions.

Impaired Functionality

Another option is to alter the functionality of sperm. This involves temporarily modifying their ability to move or fertilize an egg. By focusing efforts on sperm biology, more specific and less invasive methods are being sought.

Safety Challenges and Side Effects

The safety of new contraceptives is a crucial aspect that needs to be carefully addressed. There are concerns about the side effects that may arise from these treatments.

Hormonal Effects

Historically, many hormonal approaches have been associated with adverse effects, such as changes in body weight or mood swings. Therefore, the hormonal implications of new compounds in development are carefully evaluated.

Non-Hormonal Alternatives

Given the concern about hormonal side effects, many researchers are exploring non-hormonal alternatives. These methods aim to offer safe and effective options that minimize health risks for men.

Recent Advances in Research

The development of male contraceptives has made remarkable progress in recent years. Researchers have focused their efforts on non-hormonal alternatives and fast-acting methods, offering new hope for male contraception.

Non-hormonal developments

Research has focused on compounds that do not alter men's hormonal balance, seeking safer options with fewer side effects.

Compound YCT529

YCT529 is a non-hormonal male contraceptive that has shown promising results in studies with mice. This compound works by blocking the RAR-α protein, essential for sperm formation, achieving an efficacy close to 100%. Importantly, fertility is restored within four to six weeks after discontinuation of treatment.

STK33 inhibitors

Research at Baylor College of Medicine has identified serine/threonine kinase 33 (STK33) as a target for male contraception. Inhibiting this protein resulted in temporary infertility in animal models, leading to the development of compounds that have shown efficacy in preliminary testing.

Fast Acting Contraceptives

Efforts have been launched to create immediate-use contraceptives, representing an innovative approach to male contraception.

Efficacy and Human Studies

A recently investigated drug acts on the enzyme soluble adenylyl cyclase (sAC), involved in sperm motility. This product can be administered 30 minutes before sexual intercourse, showing immediate and temporary results.

Technology in Clinical Trials

Technological advances have made it possible to optimize clinical trials, facilitating the research of these new contraceptive methods. Tests are carried out rigorously to ensure the efficacy and safety of the compounds developed.

Why use a male contraceptive method?

Male contraception is not just a medical alternative; it is a gateway to equity in family planning and an opportunity for men to actively participate in key decisions about their reproductive future.

For a long time, the responsibility of avoiding unwanted pregnancies has fallen almost exclusively on women, who have borne the physical and emotional side effects associated with methods such as the pill, intrauterine devices (IUDs) or hormonal injections.

But why should male contraception be considered a priority? Here are several compelling reasons:

1. Shared responsibility in the couple

In a healthy relationship, important decisions, such as family planning, should be shared. By taking on some of this responsibility, men demonstrate commitment and respect for their partners. Using a male contraceptive method is a way to balance the load and offer women a chance to take a break from methods that often affect their physical and emotional health.

• Practical example: If a woman has been on the pill for years, her partner may opt for the male contraceptive as a way to ease that burden. This fosters a more equal and supportive relationship.

2. Personal control over fertility

By adopting a male contraceptive method, men take direct control of their fertility. This is especially important in situations where they wish to avoid unplanned pregnancies, regardless of the measures their partner may be taking.

• Common reasons for opting for personal control:
  • Avoid pregnancy during casual relationships.
  • Make sure you don't become a parent until you are fully prepared, emotionally and financially.
  • Have the peace of mind of knowing that you are not dependent exclusively on the methods used by the other person.

3. Less side effects for the couple

Female contraceptive methods, although effective, often have side effects such as:

• Humor changes.
• Loss of libido.
• Weight gain.
• Headaches or migraines.

By opting for a male method, the need for women to expose themselves to these inconveniences is eliminated. This not only improves the quality of life of women, but also reduces tensions in the relationship resulting from hormonal changes.

4. A non-permanent alternative to vasectomy

Until now, the only effective long-term male option was the vasectomy, an invasive procedure considered permanent.
Although it is possible to reverse it, the process does not always guarantee success and can be expensive.

New male contraceptive methods offer a reversible, safe and non-surgical solution, expanding the possibilities for men seeking to control their fertility without compromising their ability to have children in the future.

5. Reducing the emotional burden after an unplanned pregnancy

Unwanted pregnancies can cause conflict, financial stress and emotional problems for a couple. By using a male contraceptive, men can significantly reduce this risk, providing greater peace of mind and stability in the relationship.

Types of male contraceptives in development

Advances in male contraception fall into two main categories: hormonal and non-hormonal.

1. Hormonal contraceptives

These methods work by modifying male hormones to disrupt sperm production without permanently affecting fertility.

• Male contraceptive pill:
  • Key component: Dimethandrolone undecanoate (DMAU).
  • How it works: This compound, an analogue of testosterone, suppresses sperm production while maintaining libido.
  • Current status: Clinical trials show that it is safe in short cycles (28 days), with mild and reversible side effects such as fatigue or acne. However, long-term studies are still needed to confirm its definitive efficacy.
• Hormonal gel:
  • Composition: A mix of testosterone and progesterone.
  • Application mode: It is applied to the skin of the chest and is absorbed quickly.
  • Advantages: Non-invasive method, easy to use and with reversible effects.
  • Clinical trials: Recent studies with 450 couples have shown promising results, with minimal side effects and high acceptance.

2. Non-hormonal contraceptives

These methods seek to interfere with the functionality of sperm without altering the body's hormones in the male hormone cycleAlthough they are in the early stages of development, they represent an interesting option.

• Vasalgel:
  • An injectable polymer that temporarily blocks the vas deferens, preventing the release of sperm.
  • Reversible by a second injection.
  • Currently in preclinical trials.
• Enzyme inhibitors:
  • Compounds that attack key proteins necessary for sperm to be functional.
  • Still in the early stages of research.

What is the male contraceptive pill and how does it work?

Dimethandrolone undecanoate (DMAU), this is the name of the active compound of the new male contraceptive pill which is already being tested. The chemical formulation was presented at the last Endocrine Meeting in Chicago (March 16, 17 and 18 in Chicago) and everything points to it could be marketed in the coming years.

With this news that has been in the media day after day since then, you are sure to have a lot of doubts and questions. From Low T Center®, we will try to solve the most frequent ones: How does it work? Is it safe? Is it effective?

In theory, It would work in a similar way to the contraceptive pill that we already know; the female one. Thus, we would take a daily pill (orally) to prevent spermatogenesis or, in other words: the formation of sperm.

This compound is an analogue of testosterone that has the property of inhibiting
endogenous production of testosterone in men, in addition to suppressing the production of
sperm, so it can be used as a male contraceptive method.
Among its properties is that, taken orally, it does not cause liver damage like other
anabolic compounds similar to testosterone. This makes it easier to use, as it meets one of the fundamental requirements for acceptance as an effective contraceptive method.

 

This new contraceptive method opens up a whole range of possibilities for planning reproduction between couples, freeing the female partner from a burden that they have usually borne alone when couples did not use a condom.

Is the male contraceptive pill effective?

It is probably too early to say as research and clinical studies are still being conducted. «Studies have recently been conducted to test its effectiveness.» effectiveness as a contraceptive method in men, used in conjunction with a progestogen."

As reported by the Endocrine Society of the United States at ENDO 2019, A new pill has been successfully tested on a group of 40 men over the past few months. In these latest trials, men took the contraceptive pill daily for 28 days and, according to those responsible for the project, these They did not experience any serious side effects.

It is worth noting that the side effects faced by the study participants (headaches, acne or fatigue) were completely reversed upon completion of the treatment. Likewise, Only five subjects were recorded as experiencing a mild lack of libido. and two others who experienced mild problems related to sexual function.

Composition of male contraceptive

The new compound (11-beta-MNTDC) in the pill turns out to be a modified hormone that has the combined actions of androgen and progesterone.

"Our results suggest that this pill, which combines two hormonal activities in one, will decrease sperm production while preserving libido."

Christina Wang, principal investigator and associate director of the LA BioMed Clinical and Translational Science Center.

While the success of this latest study might lead one to think that the drug could be commercialized imminently, the reality is somewhat different. This is mainly due to the following reasons:

The 28-day treatment interval appears to be too short a period to prove optimal sperm suppression. Further research studies with longer durations and cycles will be needed.

In Wang's words, although Male contraception is getting closer every day, it will still take years before it is available on the market with sufficient guarantees of safety and reversibility.

Is the male contraceptive pill safe? Side effects

All studies and clinical trials conducted to date indicate that, for the time being, the male contraceptive pill is not free of side effects.

However, it will be safe in the coming years if it continues in the same line of work as until now. In a study carried out at the University of Washington: it was proven that the male pill is effective as a contraceptive method, but with some complicationsas the : decreased testosterone levels, weight gain, la depression and decrease in HDL cholesterol and, in turn, the increase in bad LDL cholesterol.

Clinical trials with male contraceptive gel

A few weeks ago, 450 couples took part in a clinical trial at the University of Edinburgh to test the famous male contraceptive. This study aimed to evaluate the efficacy and safety of a new form of contraception for men, which comes in an innovative format.

Instead of the traditional contraceptive pill, the gel version was tested. This gel contains a mixture of testosterone and progesterone, two key hormones in regulating male fertility. The application of the gel is simple: it is applied to the skin of the chest and is absorbed in a matter of seconds, offering a practical and non-invasive alternative to other contraceptive methods.

Progesterone, one of the male hormones, plays a crucial role in this process. Its main function in the gel is to reduce sperm production to a minimum, which prevents fertilization and, therefore, prevents pregnancy. On the other hand, the testosterone present in the formula compensates for the decrease in sperm production, ensuring that the man's hormonal levels remain balanced and that the situation is reversible once the gel is stopped.

This innovative approach could significantly change the landscape of male contraception, offering men another option to take shared responsibility for family planning. You may be interested in: types of testosterone.

What trial participants say

One of the participating couples, made up of a 29-year-old man and a 27-year-old woman, has been testing the gel for 6 months now and their comments about it could not be more positive. She says it doesn't cause her any physical discomfort beyond a small rash and an increase in libido.. She, for her part, is delighted to know that she will soon be able to take a break from her female contraceptives. And as you probably already know, Hormonal contraceptives intended for women are quite aggressive with their bodies.

Although this trial is not yet complete and there is still another, even larger study to be conducted, it is expected that the marketing of this and other male contraceptive methods will be available in the coming years.

This clinical trial, although promising in the area of ​​contraception, is too limited in number of patients and duration to be decisive. The consequences of the suppression of endogenous testosterone production and the possible appearance of symptoms of hypogonadism in men undergoing this therapy are also pending assessment.
