Sperm can reach the fallopian tubes surprisingly fast, with the quickest reaching in as little as 15-45 minutes, while others take 30 minutes to a few hours, though the journey to actual fertilization can involve sperm waiting for days as the cervix acts as a reservoir, allowing a continuous supply to reach the egg within the 12-24 hour window an egg is viable.
After ejaculation, millions of sperm enter the vagina, but only a small number actually make it to the fallopian tubes to meet the egg. They can get there in half an hour to a few hours, depending on a bunch of things. Sperm motility: Fast, healthy swimmers are more likely to reach the egg and fertilize.
You cannot get pregnant until and unless you release a viable egg and your partner adds viable sperm. Sperm deposited prior to ovulation remains viable for 2--3 days. It can hang out in your uterus but you cannot physically get pregnant until you release that egg.
Only a very small fraction of ejaculated sperm actually make it all the way to the egg. Around 300 million sperm are typically released during sex, but only about 200 sperm will reach the egg. This is still a pretty big number since we only need one sperm to fertilize an egg.
Fertilization is not just a race where the fastest sperm wins—it's a far more selective and complex process. Research shows that the egg, along with its surrounding follicular fluid, releases chemical signals (chemoattractants) that actively guide sperm toward it. However, not all sperm are attracted equally.
Sperm can live inside a woman's body for less than 5 days. A released egg lives for less than 24 hours. The highest pregnancy rates have been reported when the egg and sperm join together within 4 to 6 hours of ovulation.
Not usually. You may notice signs that you've ovulated, such as changes in your cervical mucus or basal body temperature. However, most people don't feel fertilization. You may feel a dull ache or experience light spotting several days after conception.
Possible Indicators That Sperm Has Reached the Uterus
These include condoms (both external and internal) as well as the diaphragm, cervical cap, sponge, and vaginal spermicides. Condoms are also known as "barrier" methods of birth control; they physically block or otherwise prevent sperm from entering the uterus and reaching the egg for fertilization.
The protected sperm with the greatest motility travel through the layers of cervical mucus that guard the entrance to the uterus. During ovulation, this barrier becomes thinner and changes its acidity creating a friendlier environment for the sperm. The cervical mucus acts as a reservoir for extended sperm survival.
Fast-swimming sperm can reach the egg in a half an hour, while others may take days. The sperm can live up to 48-72 hours. Only a few hundred will even come close to the egg because of the many natural barriers that exist in a woman's body.
This means that it is quite possible to conceive from intercourse during a period as sperm can survive for up to 7 days waiting to fertilise the egg. In a longer cycle, ovulation will occur much later in the cycle, for example around day 21 in a 35 day cycle.
Among healthy women trying to conceive, nearly all pregnancies can be attributed to intercourse during a six-day period ending on the day of ovulation. For practical purposes, the timing of sexual intercourse in relation to ovulation has no influence on the sex of the baby.
Among the causes that can lead to embryonic implantation failure are genetic alterations in the embryo, namely, the egg or sperm. Additionally, some embryos may have disorders in the zona pellucida, which hinders their ability to hatch and separate in the implantation process.
For withdrawal to work as well as possible, you must do it right every single time. Always. So always pull out BEFORE ejaculation, and always make sure to ejaculate (cum) away from your partner's genitals. This is important because pregnancy can happen if even a little bit of semen gets in the vagina.
Problems with making healthy sperm are the most common causes of male infertility. Sperm may be immature, abnormally shaped, or unable to swim. In some cases, you may not have enough sperm. Or you may not make any sperm.

How to Confirm Whether Sperm Went Inside
Tender breasts, swollen breasts, and breast changes are among the very first signs and symptoms of pregnancy, appearing 2 to 3 days after conception. The symptoms will be similar to those experienced before menstruation, marked by a sense of fullness, and tingling in the breasts.
Of all couples trying to conceive: 30 percent get pregnant within the first cycle (about one month). 60 percent get pregnant within three cycles (about three months). 80 percent get pregnant within six cycles (about six months).
