Please use your logic anon.

Yes, some sperm will decline in quality. But the vast majority of lower quality sperm also have motility problems or physical characteristics that prevent it from getting to and fertilizing the egg.

The studies suggesting correlation with schizophrenia and other illnesses have major methodological flaws. As with many peer review articles they are simply propaganda.

A man who lives to 80 and can reproduce is among the top 1% in genetic quality and will extend the vitality and lifespans of humans.

Your children will be dysgenic because you decided to listen to your thot tendencies and indoctrination propoganda.

I know. I am very discouraged that the 'Biology major' doesn't understand germ cells and meiosis or that the germ cells are both with you, male or female from birth but that gamete formation occurs the same in both males and females; it is not like gamete formation is different for either sex. Germs cells are with both from birth and meiosis (the formation of gametes) occurs in both sexes. There is no real difference between the formation of gametes except quantity (the male produces more gametes because he has more viable gametes from each round of meiosis while the female normally only produces one out of four) BUT there is no 'age difference' in the quality of the cells from male to female. Both are born with germ cells that mature into gametes, both undergo meiosis when it is time to reproduce, both carry the environmental damage from whatever shit they did to their bodies in their lifetime. I really don't know where this pseudoscientific bullshit comes from that I hear spouted on /pol/ all the time.
