In a couple trying to conceive, male factor might be solely responsible for 30% and in 20% or it might be a contributory factor. So to sum up in approximately 50% couples trying to conceive there might be an issue with the husband interfering with conception. In such a case a male infertility specialist should be looked for.
How do you diagnose male infertility? A thorough history and physical examination are the first line in diagnosing male infertility. The backbone of investigating the husband is semen analysis. This simple, non invasive test can give us wealth of information. In simpler lay man terms a man must be producing healthy motile sperms in millions of number which are able to fertilise egg. So if there is any issue with number (COUNT), movement ( MOTILITY) or quality (MORPHOLOGY) of sperms, there will be difficulty in penetrating egg (FERTILISATION) resulting in infertility.
