Common myths about male infertility are:
Boxers should be worn because it’s not as tight as the brief, which is believed to cause high temperatures in the scrotal area and affecting sperm production leading to fertility problems in males. True that increased temperature can affect sperm production but it is uncertain and no study has done to prove that it is due to the tightness of the brief.
Age does not affect fertility. The truth is as a man ages, the quality and number of sperms decline gradually. But it can decrease rapidly if a man gets/ develops a health problem that affects sperm production such as varicocele, sexually transmitted infection and urinary tract infection.
Obesity can cause male infertility. Yes, this is true because obesity can affect hormone levels including those that stimulate the production of healthy sperms thus resulting to fertility problems in males.
Having sexual intercourse daily with your female partner will increase the chances of pregnancy. Not true because if any of the couples have a fertility problem, this should be corrected so pregnancy could be possible. Ejaculation every day lowers sperm count but with better quality of sperms.
