Is conception sex any different than sex for fun? Obviously, you'll need to stop using birth control. But does sex need to change?

Generally speaking, conception sex isn't different than sex for fun. There are, however, things you can do to improve your chances of conceiving.

First, it would help to understand what is conception.

What Is Conception? And How Does It Happen?

Conception is the moment a sperm fertilizes an egg.


In order for conception to occur naturally (not talking about IVF treatment here), sperm must find their way from the vagina, up through the cervix, through the uterus, and finally, into the fallopian tubes.

Conception usually occurs inside the fallopian tubes. (Not in the uterus, which is where a lot of people assume it happens.)

When an egg is released from the ovaries, it will be drawn into the fallopian tubes by tiny fingerlike projections. The egg travels down the tube, where there should be sperm waiting.

One of the sperm cells must penetrate the egg for fertilization to happen. 

A fertilized egg is known as an embryo. 

The embryo will then travel down the fallopian tube towards the uterus. If all goes well, it will implant itself into the uterine lining, or the endometrium

When this happens, you're pregnant! 

Timing for Conception Sex Is Important

Sex for fun can happen anytime.

However, if you're trying to have conception sex, there are just a few days every month when sex has the best chance of leading to pregnancy.

There are many ways to determine the best time for conception sex and knowing when your most fertile time is can help you get pregnant faster.

However, don't think you should not have sex the rest of the month.

In fact, having sex frequently can lead to healthier sperm.

Use Only Sperm-Friendly Lubricants

The best lubricant for conception sex is your own cervical fluids. In fact, cervical mucus increases right before you ovulate.

Also known as egg white cervical mucus (because it looks like raw egg white), it serves two purposes:

  • to help the sperm swim and survive
  • to increase your sexual arousal (biology's way of making sure you have sex at the right time!)

While cervical mucus should increase around ovulation, that's not true for all women.

There are a variety of reasons for a lack of or lower amounts of cervical fluid, including... 

Lubricant may be necessary to have enjoyable sex.

When you're having conception sex, it's important not to use regular lubricants.

Studies have shown that they can harm sperm, keep them from swimming well, and even kill them. Instead, you should try to use sperm-friendly lubricants.

Fun Is Still Important During Conception Sex!

Sex for fun won't always lead to conception...

but conception sex should still be fun!

In fact, having more fun during sex may boost your chances of pregnancy success.

Research has found that lengthier foreplay time can lead to higher sperm counts.

Female orgasm that occurs close to the time of ejaculation, or after ejaculation, has also been found to slightly increase conception rates.

Don't misunderstand -- fun sex will not cure infertility and boring sex can't cause infertility.

But fun sex just may give you a slight boost towards success.
