 Hello, I am Dr. Varshan, I am a Euro-Andrologist, practicing at Manipal Hospital's Bangalore. There was an era where people presume fertility is an automatic right, okay, God will give me fertility and I will have a baby because my parents had the baby. Now we do realize that there are several factors which are playing a role, most importantly environmental factors and we see that delaying a pregnancy leads to problems in almost 15 to 20% of couples and delaying a pregnancy beyond 30 years of age is fraught with problems in about 20% of couples. So if you're looking at having an ideal time or an ideal pregnancy it's still less than 30 for the couple. Secondly, male always felt that I can always conceive, even at the age of 60 we have had people who have conceived, even at 70s had children, so I have an automatic right, nothing will go wrong with this problem. But we are an era of radio frequency radiation and we are an era of pollution, we are not the same globally in terms of temperatures and test is exposed to these kind of insults which is causing a dynamic shift in the DNA pattern of this sperm and consequently many men are realizing that age is a critical factor even for men to have a pregnancy. So the way to look at it is that I would advise that if you are keen on a pregnancy and you are already crossed 30 years or 35 years of age you should even do it pre-marital to know whether you have a problem. The second is the wife or the partner whom you have is a critical factor to create a pregnancy. If she is already crossed 35 irrespective of your age I would still advise to find out whether your fertility profile is good because it's a combination of factors. If the male is extremely fertile even if the female is a little sub-fertile you get away with a pregnancy. If the female is extremely fertile if the male is a little sub-fertile they will get away with a pregnancy but if both are sub-fertile the chances are they'll not get away with a pregnancy. So consequently early evaluation or at best after six months to one year of trying you should get yourself evaluated so that you don't land up in surprises at a later state and the early evaluation helps you to correct majority of problem then later evaluation.
