The Best Time For Intercourse & Fertility: 100,000,000 Sperm or Bust

While sex is fantastic, when you’re trying to have a baby, there’s a desired outcome that should guide your actions. Ideally having intercourse when the man has the highest number of fresh sperm and the woman is ovulating and in the zone for optimal fertility.

More sex doesn’t always equal better odds of getting pregnant. It’s undeniable that having sex in the time period when you’re actually ovulating is crucial to conception, where we’ve gotten it wrong is thing that more sex is better. How can that be you ask, more sex is always better. Isn’t it?

Okay let me explain this. I have seen couples trying to conceive using fertility apps to estimate the woman’s ovulation. I have seen couples who have lots of sex between Day 9 and 16 only to find themselves overwhelmed with sexual exhaustion by Day 22, when she’s actually ovulating.

What to do? For several years I instructed couples to purchase ovulation predictor tests and have copious amounts of sex around ovulation. After 3 months, they can calculate an average day of ovulation and then use that information going forward to time conception. I was wrong. I was wrong and now I’m here to propose a new schedule of timed intercourse and the science too.

Alright, this is it: Sex every two to three days. That’s it.

Why is this a good idea?

To determine the best time for intercourse, you need a schedule that enables the couple to have intercourse when the man has the highest number of fresh sperm and when she is ovulating and in her prime to get pregnant – no kit needed. This is because the sperm live for 5 days inside a woman and egg is viable for 2 days. In short, by having sex only every two to three days with no seminal emission elsewhere- Guy’s, no masturbation- sorry– there is no way to miss her ovulation, whether ovulation occurs on Day 8 or 21.

If a man has no seminal emission between “sessions”- as one of my patients calls it- his ejaculate will have approximately 100,000,000 sperm after 2-3 days of abstinence.

Why are so many sperm needed if only one sperm is needed for conception? Basically it’s a hard trip and a numbers game. A post for another time.

The 100,000,000 sperm count is ideal because at the time that the sperm encounters the egg there should be 4,000 sperm present. The head of each sperm contains an enzyme that breaks down, more specifically digests the shell of the egg. It is a collaborative effort that allows one sperm to get in. Add your own sport analogy if need be.

So what happens if a man has only 20,000,000 sperm in his ejaculate? There are just not enough sperm to weaken the egg shell to make fertilization possible.

I would love to hear your thoughts, leave a comment below and I will be sure to answer.
