Unexplained Infertility in Men

Infertility is often associated with women but that is obviously not true. In almost 30% of infertility cases, the male factor infertility is responsible. Thus, evaluating male fertility is equally important when a couple suffers from non-conception. But sometimes fertility test reports do not reveal the actual reasons for infertility. This condition is medically termed as unexplained infertility and if it is the test report of the male then it will be termed as unexplained infertility in men.

What is Unexplained Infertility?

Unexplained infertility is a condition when the actual reason behind infertility remains hidden after conducting several fertility tests. In this case, the healthcare provider failed to diagnose the cause of the infertility of a person or a couple. Generally, couples suffering from infertility have to go through lots of fertility tests to get confirmation about what reasons are causing infertility in them.

Female infertility occurs most of the time because of ovulation-related issues and for men, it happens due to issues related to sperm. There can be several other factors causing infertility in both men and women. But in case of unexplained infertility, everything seems normal in the test reports as the fertility tests fail to find out the cause of infertility. Healthcare providers will only declare unexplained infertility after testing both partners. Male unexplained infertility may seem to be a hopeless condition where to-the-point treatment cannot be given due to the lack of clarity. But with proper medical assistance, conception is possible.

Unexplained infertility in men is a condition when routine analysis of semen does not figure out any abnormalities regarding its quantity or quality or shape or structure. Healthcare providers will only declare a man to be suffering from unexplained male infertility if both his physical and endocrine checkup results are normal and his female partner has already been ruled out from infertility factors.

Causes of Unexplained Infertility in Men
