Can You Find The Reason?

Choosing to start a family is an exciting time for couples. Yet, for many couples, infertility is a sobering reality. About 12-16% of couples struggle with infertility. Male factors, or male infertility, contribute to roughly half of these cases. The underlying causes of most cases of male infertility are easily identifiable. Poor sperm count, low motility, or abnormal shape are easily identified with standard tests. Yet, some cases cannot be easily explained. On the surface, everything looks fine, but there is persistent infertility despite standard testing saying otherwise. These unexplained infertility cases stem from uncommon reasons or factors that require unique testing and treatment.

It's in your genes

Some genetic abnormalities can impact fertility without affecting other aspects of health. These are uncommon and difficult to detect in standard fertility testing. For instance, men with Klinefelter syndrome can have testicular dysfunction and infertility. Research shows this condition impacts 1 in 500-1000 men. The condition can lead to testosterone production issues and low sperm count. Men with Y-chromosome microdeletions represent another significant genetic cause, with deletions in specific regions affecting sperm production. These conditions can only be detected with genetic testing.

Possible congenital abnormalities

Some men are born with rare developmental conditions that go on to cause male infertility. An example is cryptorchidism, where the testicles fail to descend into the scrotum at birth or early life. If this is not treated at an early age, testosterone and sperm cell production become impaired. Some issues are urogenital abnormalities, impacting the urinary or genital tract. Damage to the genital tract from infections, surgeries, or tumors is another possible cause. Some congenital issues are not apparent until a man or couple is ready to conceive.

Immunological and infectious barriers to conception

The immune system is an overlooked factor in male infertility. Antisperm antibodies, for instance, develop in 9-12% of infertile men, though these numbers may be higher. When this occurs, the body mistakenly attacks sperm cells and creates antibodies that further impact sperm production. Certain fungal infections, sexually transmitted infections (STIs), tuberculosis, or conditions like prostatitis can impact reproductive health. Without the right testing for specific infections, these issues can be missed.

Uncommon hormone disruptions

A significant number of male infertility cases can be traced to hormone imbalances. There are some cases where the underlying cause is much more uncommon, nuanced, and often overlooked. Some men have irregular prolactin levels, which affect the production of the gonadotropins responsible for sperm production. Rare hormone conditions like Kallman syndrome, where the body does not produce gonadotropin-releasing hormone (GnRH), cannot conceive naturally. These men may have other health concerns, such as delayed puberty.

Exploring your treatment options

The challenging part is uncovering these rare or uncommon causes of male infertility. In some cases, initial testing of sperm or hormones may not reveal a known issue. The goal is to look at multiple areas of health. Specific blood tests, genetic testing, or medical diagnostic procedures may be the best way to uncover the true cause of infertility. With a more concrete diagnosis, treatment can begin. Most men will benefit from assisted reproductive technology (ART), which can include advanced sperm retrieval techniques. Going straight to in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI), where a single sperm is used to create embryos, produces better results.

It helps to dig deeper

Finding the answers to male infertility is not always straightforward. Infertility is a complex function, and some rare underlying issues can prevent men from conceiving. Men trying to start or grow a family should seek specialist advice, especially if getting pregnant with a partner is difficult. After reviewing the more common reasons for infertility, the specialist can go a bit deeper. With the right testing and diagnosis, treatment becomes easier. In many of these uncommon cases, assisted reproductive techniques are necessary. Knowing the possible underlying causes makes the fertility journey easier to navigate and increases the chances of success.
