Male factor infertility can be caused by a variety of genetic and hormonal factors.


Explore some of  the most common genetic and hormonal causes of male factor infertility and their effects on male reproductive health.

Genetic Causes of Male Factor Infertility:

Klinefelter Syndrome:


Men with Klinefelter Syndrome have an extra X chromosome, which can lead to lower levels of testosterone and decreased sperm production.​

Y Chromosome Deletions:


Men with Y chromosome deletions may have reduced sperm production or even the absence of sperm in the semen.

Cystic Fibrosis:


Men with cystic fibrosis may have a congenital absence of the vas deferens, which can prevent the transport of sperm.

Hormonal Causes of Male Factor Infertility:



Hypogonadism is a condition in which the testes produce insufficient amounts of testosterone, which can lead to decreased sperm production.



Hyperprolactinemia is a condition in which the pituitary gland produces too much prolactin, a hormone that can suppress the production of testosterone and sperm.


​Thyroid Disorders:


Thyroid disorders such as hypothyroidism or hyperthyroidism can disrupt hormonal balance and affect sperm production.

It is important to note that genetic and hormonal causes of male factor infertility are not always easy to identify, and often require a thorough evaluation by a urologist or reproductive endocrinologist. Treatments may include medications, hormonal therapy, or assisted reproductive techniques, depending on the underlying cause of infertility.


If you suspect that you may have male factor infertility, it is important to seek the advice of a healthcare professional who specializes in male reproductive health.
