Male infertility refers to the condition, where males are incapable of producing reproductive hormones or could not produce enough hormones to make women fertile. Infertility in men can be caused by many reasons, which includes environmental, physical and mental health, etc. It can occur in any stage of a man’s life but, most of the men suffer from this at later ages. This infertility can cause many problems apart from fertility; it leads to many physical and mental illness.
In Norway The mean age of the 99 men was 31 years, and the range spanned from 20 to 45 years. The mean age of their partners was 30 years (range, 21–42), and 86% were less than 35 years old. The self-reported TTP, recorded as the number of cycles, including the cycle of fertilization, is shown in Figure 1. For 2 persons there was no information on TTP. Thirty-nine percent (38 cases) of the 97 couples with TTP recorded conceived during the first cycle, whereas 92% (89 cases) became pregnant within 12 cycles
