Reproduction is one of the more important mechanisms, that we humans are equipped of. In the absence of this, some of us may consider the valuable loss of life. This is probably why once a couple does not conceive within a 1-year period of unprotected sexual intercourse, they become anxious that they may be subject to infertility.

In fact, the symptom of not conceiving in 1 year alone is one good basis for diagnosing infertility.

There is not much that the medical community hasn't unraveled yet when it comes to infertility. This article will focus on the causes of infertility for both men and women.

Causes of Female Infertility

Endometriosis- this is a condition characterized by the growth of the endometrial tissue outside the uterus. This tissue is the substance women discharge during menstruation.

Ovulation problem- a condition that arises from abnormality in the release of hormones that drive the release of mature eggs from the ovaries.

Poor egg quality- the weakness or damage in the egg cells usually characterizes poor egg quality. Age is primarily the root cause since as women mature, their eggs mature with them. This condition eventually leads to menopause.

Polycystic ovary syndrome- formation of small cysts in the ovaries may be the result of irregular ovulation or hormonal imbalances.

Female tube blockages- once the passage of the eggs towards the uterus or the sperm towards the ovaries is blocked, conception would be impossible since the meeting of the two cells won't facilitate. Causes of this condition may be pelvic inflammatory disease and several forms of sexually transmitted disease.

Causes of Male Infertility

Male tube blockages- this may occur either at the epididymis or the vas deferens, both of which are sperm passages. However, varicoceles located at the testicles account for the leading cause of this condition.

Sperm problems- this could be anything from the absence of sperm cells to low sperm count along with poor sperm quality and sperm deformation.

Sperm allergy- this may the product of the immune system's reaction towards any phenomenon that attracts brain signals sending the reaction of the system. Men usually experience this after having vasectomy.

Combination of Female and Male Factors

This occurs when both couples present conditions that may be identified as causes of infertility.

Unexplained Infertility

This probably is the catch-all of causes when physicians don't find any results after conducting intensive study of the case.
