As a general rule, the more sex you have, the more likely you are to get pregnant.
If you make love three to four times per week throughout your cycle, you are almost certain to have intercourse at least once during your fertile window (the last few days before ovulation, when conception is possible). And for many couples, this is all it takes to get that positive pregnancy test.
If you don’t have the possibility or the energy to make love every other day throughout the month, timing becomes all the more important.
Using ovulation tests and checking your cervical mucus will help you to know when ovulation is approaching, and you should try to have as much sex as possible during the last four to five days leading up to ovulation – every day if possible, and at least every other day.
Don’t stop having frequent intercourse until you are certain ovulation is over.
Intercourse frequency and sperm quantity
You may have heard or read that “too frequent” intercourse may reduce the man’s sperm supply, but this is not true for most couples.
If you know your man has a sperm count issue, you should consult his doctor for the best intercourse strategy, but for healthy couples trying to conceive there is no such thing as too much sex.
While it is true that frequent lovemaking slightly reduces sperm concentration, this is compensated by the fact that every act of intercourse during your fertile window increases your chances of getting pregnant.
Intercourse frequency and sperm quality
Abstaining from sex with the idea of saving sperm until ovulation is a big mistake. While the number of sperm cells may increase with less frequent ejaculation, the percentage of normal, healthy sperm cells quickly decreases.
In other words, delaying ejaculation may cause the sperm to “go stale”.
In order to make sure a good supply of fresh, healthy sperm cells are available when you are at your most fertile, try having intercourse at least two to three times per week during the first half of your cycle and until you are sure ovulation is over.
