Why does it take months for some couples to conceive despite being fertile and having frequent sex?

All,

So a friend of mine is planning a family and haven’t gotten pregnant yet. Her gynac said they it may happen right away or may take even a year to conceive. Well, i don’t really understand this.

If a fertile man and woman are having frequent sex, what really leads to not getting pregnant?

We were having a little trouble concieving and my wife asked her OBGYN what she could do to get pregnant. His answer was “Be 18 and have unprotected sex in the backseat of your boy friend’s car.” It took us a few more months, but we had fun trying.

Scrolled through some good explanation but didn’t see that a woman is only fertile up to (but probably not even as long as) 6 days per cycle/month. Regular sex doesn’t actually really matter. Sex 24-48 hours before ovulation does. After ovulation (typically about two weeks before the period begins), absolutely no amount of regular sex is going to get anyone pregnant.

There’s a lot of good answers here but something I haven’t seen mentioned is that it didn’t used to be so hard. The current level of infertility is new to the last 30-40 years. There are a number of factors that play into this:

1. Male sperm quality has decreased about 60% over the last 50 years. There isn’t a clear scientific consensus as to why, but it’s a major factor in trying to conceive.

2. A woman’s peak fertility is between 16-24. Up until recently this was also when most women tried to start a family. The average age of first children now is over 30, where egg viability is half that of the peak window and it drops by another 50% after 35.

Just these two factors alone significantly decrease your chances of getting pregnant on the first try. Add in all the other things people have said and getting pregnant is hard in today’s society.

People are throwing a bunch of different reasons out here and all can have something to do with it, but we went through IVF with probably the most prominent fertility doctor in the US and as he said, “we don’t know. Sometimes it’s unexplainable”.
