Prevalence of Male Infertility is 50%, Say Andrologists at Rutgers

The prevalence of infertility is 50% attributed to men. Blood tests for testosterone, semen analysis, autoimmune factors, genetics, and a clinical examination are done on the men to evaluate infertility. Men face a lot of stigma when it comes to infertility.

A couple is considered infertile if they have not conceived after one year of trying to conceive, without contraception. Andrologists focus on the treatment of male infertility, sexual dysfunction, benign prostate hyperplasia, and erectile dysfunction.


The first step in identifying and treating infertility is often rigorous testing for women. However, only 50 percent of infertility is attributable to the female partner alone, 50 percent of couples have a male factor, according to Nikhil Gupta, MD, assistant professor of surgery. In May 2018, Dr. Gupta became the first andrologist and male sexual function subspecialist appointed to the faculty of Rutgers Robert Wood Johnson Medical School. He focuses on the treatment of male infertility, sexual dysfunction, benign prostate hyperplasia (non-cancerous enlarged prostate) and erectile dysfunction.

In the world of modern medicine, andrology, is a relative newcomer. The field acquired its name only 70 years ago, bringing under one umbrella a variety of areas concerned with male reproductive health, including urology, endocrinology surgery and genetics. A couple is considered infertile if they have not conceived after one year of trying to conceive, without contraception. A couple will usually seek a consultation with a fertility specialist after trying to conceive for a year without success.

"Often, when no pregnancy occurs, the woman is the first to see an infertility specialist, believing that the problem must originate with her,"says Dr. Gupta. If the woman's specialist finds no issues, she and her partner would most likely be referred to a specialist in male infertility. But in fact, the causes of infertility are equal between men and women.

As an andrologist, Dr. Gupta's role in helping a couple to conceive focuses on the man, but he always starts out by meeting with both partners. He devotes a lot of time to helping the couple to understand that infertility is neither partner's "fault," emphasizing instead what the diagnostic tests will show and how their results may help the couple start their family. Infertility creates a special kind of anxiety in men, says Dr. Gupta. "Boys are raised to believe that if you try hard enough, you can develop the strength to overcome challenges. Some of my patients fear there is something wrong with their manhood, because they haven't been able to father a child."

Evaluation starts with blood screening to determine the signaling ability of the patient's testosterone, the hormone that stimulates sperm production. Subsequent semen analysis may indicate the inability of ejaculated sperm to travel efficiently through the woman's reproductive system or a low sperm count or an absence of sperm, which could stem from earlier trauma, childhood illness, undescended testis or testes or chemotherapy.

In adition to testing sperm, the andrologist will also look for autoimmune factors in the reproductive systems of either partner, as they can be toxic to sperm. Genetics can also be a factor. A blood test can detect a missing gene in the Y chromosome, a fairly common cause that is responsible for approximately 13 percent of male infertility. In addition, a clinical examination can reveal other issues leading to male infertility like encountering obstruction in the male ducts, blocking them from their route out of the testes.

One of Dr. Gupta's great satisfactions as an andrologist is to be able to help his patients father a child. On why he decided to pursue andrology as a specialty, he found it to be "incredibly hopeful" with much progress to be made and stigmas to overcome.
