Women's Health Infographic: Conception (Text Alternative)

Skip sharing on social media links

This is an infographic describing conception.

The heading reads, “6 Things to Know About Conception”

The next two lines read:

90% of women don’t know that 2 days before through the day of ovulation is the best time to try to get pregnant.

40% of women don’t know that a woman is born with all of the eggs she will ever have.

To the right is a graphic designed to look like a circular birth control pill dispenser. The graphic displays a 28-day cycle with highlights for day 1 (first day of menstrual period), ovulation (about day 14 of an average 28-day cycle), and day 28 (average cycle).

Below this is a subhead that reads, “The Science Behind Conception.” The text following this subhead reads:

Normal ovulation leaves only a small window for conception. Conception can occur only in the 6 days before ovulation through the day of ovulation. Here’s what it takes for conception to occur:

1. Semen, which contains sperm, enters a woman’s vagina.

[An illustration shows three sperm traveling into a woman’s vagina from outside of the woman’s body].

2. A mature egg cell arrives in a woman’s fallopian tube. The egg is fertilizable for only a short time (usually between 8 and 12 hours).

[An illustration shows an egg cell entering a fallopian tube from the ovary.]

3. Sperm swim into the uterus and fallopian tubes, where they can stay functional for 5 days.

[An illustration shows four sperm swimming in the uterus and fallopian tube.]

4. Sperm go through changes to become fully mature, so that they are able to bind to an egg.

[An illustration shows two sperm side-by-side. One is still while the other is actively swimming to representing activity and change.]

5. In the fallopian tube, one sperm fertilizes the egg to form an embryo.

[An illustration shows three mature sperm racing toward an egg. One is ahead of the two others and is entering the egg head first.]

6. After several days, the developing embryo moves to the uterus. There, it attaches to the uterine lining, where the pregnancy can progress. 

[An illustration shows a fertilized egg attached to the thick lining of the uterus.]
