Many couples struggle with the decision of how much sex to have when trying to get pregnant.  Having too much sex makes you tired, but having too little sex reduces your chance of pregnancy.  Here's a breakdown on exactly how much "bed dancing" you should be doing when you're trying to get pregnant as a couple.

Too much sex lowers semen quality and quantity

Scientists believe that doing the bed dance every day or every other day makes for bad quality sperm because the sperm does not have a chance to fully mature.
This is backed up by the fatigue men often feel when partners go on a plan that requires them to have sex every day or every other day.  Men feel worn out, sex quality declines, and sperm production is lowered.

Time of womens' cycle influences pregnancy success

Having sex about a week before ovulation right up until ovulation results in higher pregnancy rates for many women.  If your fertile window starts 4 days before ovulation, stop bed dancing 8 days before so that the man's sperm quality will be highest when you do have sex again.

Some statistics to clarify how much sex you should have to get pregnant

Here is a way to break it down.

• If you have sex every day while you're trying to get pregnant, you have a 38% chance of pregnancy.
• If you have sex every other day, you have a 34% chance of pregnancy.
• If you do it once a week or thereabouts, you have an 18% chance.

However, these are just rough numbers.  This doesn't take into account sperm quality (which will be higher if your frequency of sex is limited), or time of the woman's cycle (which plays a large role in pregnancy success).

Every couple is different, so it is impossible for anyone to tell you exactly how much sex you should have to get pregnant.  The best advice is simply to not stress about it; keep track of your cycle and ovulation, but have sex when you feel like it and try to enjoy sex rather than making it a chore.
