Explaining a myth

Lying on your back with your knees up or elevating your hips after sex is a widely circulated myth and has no scientific basis for improving your chances of conception.

Sperm are strong swimmers and do not need gravity to reach the egg; they can reach the fallopian tubes quickly on their own.

While lying down for a short time after sex won't hurt, it doesn't influence conception, and many experts state that the timing of sex during the fertile window is far more important for getting pregnant.

Why the Myth Persists

Feeling of control
: For couples trying to conceive, the myth might offer a sense of taking action to increase their chances.

"Upsuck" theory
: Some believe the female orgasm helps pull sperm into the cervix, but this is not essential for pregnancy.

What Actually Matters for Conception
Timing your sex
: The most crucial factor for getting pregnant is having sex during your fertile window, particularly around the time of ovulation.

Sperm's ability to swim
: Sperm are designed to travel upwards and are very resilient.

Sperm survival
: Once they reach the uterus and cervix, sperm can survive for several days waiting for an egg.

What You Can Do
Focus on the fertile window
: Track your ovulation to determine the best days for sex to increase your chances of conception.

Have enjoyable sex
: Choose positions and practices that you and your partner enjoy, as this can also positively influence conception.

Consider a short rest
: You can lie down for a short period if you wish, but there's no need to remain in any specific position for a long time.

We knew it was a myth, but we were having trouble getting pregnant the second time, so I remember my wife trying every myth, old wives' tale, and rumor, including this one. Something finally worked.

My mother told me once..... If you don't want to get pregnant until you are ready, do hand stuff.
The way she said it though. so funny.
True, sperm don't require the help of gravity (here on Earth under the average sea level gravitational pull).

But conception is about spermatozoa reaching an available ovum. How is increasing the available "pool" going to hurt?

Further,

Once they reach the uterus and cervix, sperm can survive for several days waiting for an egg.
(Emphasis added.)

can is not the same as do

which depends upon how hospitable the environment is to the spermatozoa (pH, etc.).

The swimmers are the reason. Always race to get there first.
