Sometimes the cause of infertility isn’t known and research has shown that both men and women suffer from problems known to cause infertility, with sometimes multiple factors playing a part in the cause. There are numerous reasons the woman can be infertile such as hormone imbalances, problems with the fallopian tubes, endometriosis and problems with the reproductive organs.
In men the cause of infertility is due to the number of sperm they produce or blocked spermatic cords. The infertility could be caused by any one of these reasons or by a mixture of them, with sometimes the reason being unclear.
