All I can say is it is not a good idea to muck around with Mother Nature - Let alone with God.
One of the problems in our society is that cattleman and chicken farmers are mucking around with Mother Nature too much
There is some reason, I am sure, why so many women in the industrialized world seem to have so many gynecological problems.
My youngest child and only girl is as slender as a willow, yet she started menstruating at ten and developed ovarian cysts at age 16. I never had problems like these when I was a teen, and it was almost unheard of for girls to reach puberty that early when I was growing up.
When she was in tenth grade she went on a school band trip, and in her hotel room of four, she was the only one not taking the pill. None of them were taking it for reasons of birth control--two had gynecological problems, and one was taking Accutane.
Infertility can be related to PID (which I think can be related to untreated chlamydia or some other illness) but it can also be related, I believe, to these different gynecological problems that women in bygone years, before we were eating hormone laden beef, pork, chicken, eggs, milk, and cheese, never had.
I also wonder whether this could be a reason for the upswing in homosexuality--either because of the hormone-laden foods we all eat or because women who eat hormone-laden foods affect their male fetuses.
