i was reading on an article by STREATS which covered something quite interesting, something on biological clock for men and women. after all it's a interesting fact for you and me. below is a few paras qoute from the article:

"Indeed, studies have shown that a women's fertility declines markedly around mid-30s(which worked out to be 35). but she didn't know is that men have biological clocks too....
