Approximately 15 percent of couples are infertile due to a number of causes including male sub-fertility. This means they aren’t able to conceive a child even though they’ve had frequent, unprotected sexual intercourse for a year or longer. In about 50% of these couples, male infertility may be a factor. Situations such as these can cause strain in relationships, depression and frustration due to the unknown causes of this sub-fertility. However, with medical analysis, a number of male causes can be identified, a treatment plan identified and factors rectified to provide couples with a better chance of conceiving through whichever method identified as required.
