Male infertility: How is it diagnosed and what are the treatment options?

Fertility issues and concerns about them are a deeply personal and emotional journey, one that affects both partners equally.

While discussions about fertility often center on women, it’s important to recognize that men play a crucial role in this process too.

In fact, male factors contribute to 30% of cases of infertility challenges according to research.

Let’s explore what this means, how to strengthen your reproductive health, and the steps you can take to support your fertility journey.

What does infertility mean?

Infertility is typically defined as the inability to achieve pregnancy after a year of regular, unprotected intercourse.

It’s a shared concern, affecting both partners and in 20% of cases, it’s primarily due to male factors. If you’ve been trying for a while without success, know that you’re not alone, and there are compassionate professionals ready to help.

When Should You Consider an Evaluation?

Generally, couples might consider a fertility evaluation after a year of trying. However, for women over 35 and/or men and women who have known risk factors, it might be worth having a chat with your doctor sooner – perhaps after six months.

Remember, seeking help isn’t a sign of weakness. It’s a proactive step towards your future
family.

Signs and Symptoms of Male Infertility

Many fertility issues don’t have obvious symptoms, which is why regular check-ups are so important. However, some signs that might prompt you to seek advice include:

1. Difficulty conceiving after a year of trying
2. A history of testicular or prostate issues
3. Previous cancer treatments
4. Changes in sexual function
5. Understanding any history of infertility in your family

If you’re experiencing any of these, or if you’re simply concerned, don’t hesitate to reach out to a healthcare provider.

What to Expect from a Fertility Evaluation

The thought of a fertility evaluation can be daunting, but understanding the process can help ease some anxiety.

Here’s what you can generally expect:

1. A conversation about your medical history and lifestyle
2. Blood tests to check hormone levels
3. Two semen analyses
4. A physical examination

Let’s discuss the various parts of the tests.

Hormone Blood Tests

Hormones play a crucial role in fertility. Key hormones that are checked in the male reproductive health evaluation include:

• Testosterone
• Estradiol
• Luteinizing hormone (LH)
• Follicle-stimulating hormone (FSH)
• Prolactin

The first goal of these tests is to make sure testosterone levels are in a normal range. Up next is making sure the ratio of testosterone to estradiol (estrogen) is more than 10:1.

The next two hormones on the list are Luteinizing hormone (LH) and Follicle-stimulating hormone (FSH). These stimulate the testicles to produce testosterone and sperm, respectively. When these LH and FSH values are high, think of it as the brain is sensing low levels of testosterone and sperm production, respectively, and is trying to compensate for this.

Finally, if prolactin levels are significantly elevated, it can “turn off” the other important hormone secreted from the brain critical for testosterone and sperm production (LH and FSH, for example).

Semen Analysis

A semen analysis looks at several factors:

1. Volume: How much semen is produced
2. Concentration: The number of sperm present
3. Motility: How well the sperm move
4. Morphology: The shape of the sperm

Two samples are usually requested to get a clear picture, as results can vary from day to day. This is completely normal and nothing to worry about.

Physical Examination

The physical exam allows your doctor to check for any physical issues that might affect fertility. For instance, high estradiol can cause gynecomastia (enlarged breasts in men) and can be an indicator that something is wrong with your hormone levels.

It’s a routine part of the process and, while it might feel a bit uncomfortable, it’s an important step in understanding your overall health.

Understanding Your Results

Receiving your results can be an emotional experience. Whether the news is good, challenging, or somewhere in between, remember that this is just one step in your journey.

There are often many paths forward and treatments available. That’s why it’s important to talk with your doctor about what that next step might involve. When discussing with your doctor, consider these questions:

• What do these results mean for our fertility journey?
• What are our options moving forward?
• Are there lifestyle changes that could help?
• What kind of timeline should we expect?

From there, it’s also important to:

• Talk to your partner. You’re in this together.
• Consider joining a support group. Sometimes it helps to talk to others in the same boat.
• Schedule a follow-up with a reproductive urologist or fertility specialist.

Treatment Options for Male Infertility

Every fertility journey is unique, and there are various treatment options available for male infertility. Your healthcare provider will work with you to determine the best approach based on your specific situation.

Lifestyle Modifications

Sometimes, small changes can make a big difference. Your doctor might recommend adjustments to your diet, exercise routine, or stress management techniques. They may also suggest reducing alcohol intake or quitting smoking. These changes can often improve overall health and potentially boost fertility.

Medications

In some cases, hormone imbalances or other medical conditions can affect fertility. Your doctor might prescribe medications to address these issues. For instance, drugs like clomiphene citrate or anastrozole can help boost testosterone levels without negativelywhich may also positively impactting sperm production.

Surgical Interventions

For certain conditions, such as varicoceles (enlarged veins in the scrotum), a minor surgical procedure might be recommended. These surgeries can often improve sperm quality and quantity. 10% of men presenting for an infertility evaluation are found to have azoospermia. Azoospermia refers to a complete lack of sperm in the semen test. This can occur either due to a problem of obstruction or a problem of production, both of which likely require intervention from a reproductive urologist and male fertility expert.

Treatment Options for Couples

If other treatments aren’t successful, your doctor might suggest other options.

These can include:

• Intrauterine Insemination (IUI): A procedure where sperm is placed directly into the uterus during ovulation.
• In Vitro Fertilization (IVF): Eggs are fertilized with sperm in a lab and then implanted in the uterus.
• Intracytoplasmic Sperm Injection (ICSI): A single sperm is injected directly into an egg for fertilization.

Each of these options comes with its own considerations, and your healthcare team will guide you through the pros and cons of each. It’s okay to take your time in making decisions, and to seek second opinions if you feel it’s necessary.

Closing thoughts

Embarking on a fertility journey can be challenging, but you don’t have to face it alone. By understanding your body and being proactive about your reproductive health, you’re taking important steps toward your family’s future.

If you’re reading this, the most important thing you should know is that seeking help is a sign of strength, not weakness.

Whether you’re just starting to consider your fertility or you’ve been on this path for a while, know that there are compassionate professionals ready to support you every step of the way.
