Why are girls so worried about near weight?

I agree next to the previous poster on #1 - 70 year old men still produce sperm whereas a 70 year aged woman has probably gone through menopause.

#2 - at hand is no such thing as a "resistance to sperm". I don't know where on earth they got that from, but it's totally false. Not all babyish teenagers get pregnant after have sex only once. Anyone can catch pregnant after having sex once. There's nothign age related near. You probably hear about it more because the average age of losing virginity is between 13-17 (it vary by state). So...it's just that infantile teenagers are havnig sex adn happenign to get pregnant. But...and again I reiterate...ANYONE can draw from pregnant after having sex once.

Can sperm live outside the body exposed to nouns for more than 4 hours?

#1. a man can still be a father at that age because he is still producing sperm cells. a 70+ elderly woman should have already experience menopause where on earth she stops ovulating - that is releasing eggs from her oviducts to become fertilized. the eggs are too antediluvian to be used in fertilization so that is to say why women start menopause from age 40 i think (correct me if i am wrong).

#2 babyish teenage girls can go and get pregant after having sex once because her body hasnt built up a resistance to sperm. so it is massively easy for the sperm to move up through the vagina and fertilize some egg. however after her first child it will be harder to seize pregnant in most cases since her body have defensive "cells" or antigens that make her body immuned to sperm cells since it is very soon a "foreign body" in her.

presently that FSH thing u can research that on the yahoo search engine

to the woman below, my university lecturer said (my major is biology) it is confident to become pregnant the first time but harder the next because your body do build up resistance to sperm since it is a foreign body.
