It is true that infertility do not only occur in women it also occurs in men too but the high level of casual sex relationship in this generation
Is alarming, You will agree with me that the women I mean the girls are the ones in the receiving end of the story in the situation of getting pregnant and probably refuse to keep the pregnancy by indulging in taken substances that might have a negative effect on them not being able to concieve tomorrow because they don't want to give birth to a child without being properly married, to protect family prestige pride and dignity or religion, this actually act is of the increasing side in most of our societies today which of course is one of the major reason why I brought up this topic of discussion, a lot are really happening behind the scene.
Not all young girls today are so naive or stupid that they don't know how to protect themselves. They are just like us men, some are stupid and some are smart.
I agree that sex is much more open these days but that doesn't mean girls don't know how to protect themselves. In a developed world, knowledge about sex and life is introduced into education quite early and is not too difficult to access thanks to the development of the Internet. There are many methods of safe sex and I believe that even teenagers today know, let alone young people over 18 years old.
I don't know what's going on in your country, but from what I see around me, the majority of people who are unable to have children are men. The reason is said to be because they drink alcohol, smoke or even abuse drugs...All are leading causes of sexual diseases in men, such as erectile dysfunction, premature ejaculation...or worse, infertility while the infertility rate in women is significantly lower.
