How to know sperm meet egg
Following ejaculation, the semen forms a gel that protects it from the acidic environment of the vagina. The gel is liquefied within 20 to 30 minutes by enzymes from the prostate gland. This liquefaction is important for freeing the sperm so transportation may occur. The seminal plasma is left in the vagina. 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.SEE VIDEO BY TOPIC: Major Signs Your Egg Has Been Fertilized -- How Sperm Meet With Egg

How Fertilization Happens
Pregnancy begins when a sperm fertilizes an egg. This usually occurs in the 2 weeks following the first day of the most recent menstrual period. In the first few weeks of pregnancy, a woman may have no symptoms. Some can sense that they are pregnant, but most do not suspect it until they miss the next period. In this article, gain a detailed understanding of fertilization, and learn what goes on in the first 5 weeks of pregnancy.
This feature is part of a series of articles on pregnancy. It provides a summary of each stage of pregnancy, what to expect, and insights into how your baby is developing.

The medical community measures pregnancy from the first day of the last period, even if fertilization happens several days after the period has ended. For fertilization to occur, sperm must enter the vagina. This usually, but not always, happens through sexual intercourse. There, the sperm will penetrate and fertilize an egg. Once fertilized, the egg travels down the fallopian tube toward the womb, or uterus, where it will implant in the uterine wall. Beginning in the ninth week of pregnancy, and until the pregnancy ends, doctors call the developing baby a fetus.
The egg comes either from a donor or a woman who wishes to become pregnant. In a laboratory, a specialist doctor works to fertilize the egg with donated sperm. The goal is for at least one fertilized egg to implant and develop. When the egg and sperm unite, they form a zygote. The zygote contains 46 chromosomes: 23 from the female and 23 from the male.
The chromosomes determine the genetic make-up of the fetus, including its sex and inherited physical characteristics, such as:.
They may also help shape factors such as personality, intelligence, and the risk of some health conditions. A zygote inherits one sex chromosome, the X chromosome, from the egg. It also inherits a sex chromosome from the sperm. This may be either an X or Y chromosome. If the sperm contained an X chromosome, the fetus will be female XX.
If the sperm contained a Y chromosome, the fetus will be male XY. At 3 weeks pregnant, the fertilized egg, or zygote, measures 0. The zygote will spend several days making its way down the fallopian tube. During this time, it develops into a morula, a ball of 12—15 cells. As time goes on, it will become a bigger collection of cells called a blastocyst.
At week 4 , the blastocyst implants into the wall of the uterus. The blastocyst contains an inner and an outer part. The inner part will ultimately develop into the embryo. The outer part will become the placenta, an outer shell that will provide protection and nourishment to the growing embryo.
At this point, the baby is a cluster of cells measuring approximately 0. Around the beginning of week 5 , doctors will likely start referring to the baby as an embryo, and it will be about the size of a sesame seed. You may need to take a break from strenuous exercise during pregnancy, and a doctor can help modify or develop a healthful exercise plan. During the first 6 weeks of pregnancy, there may be no indications of pregnancy.
However, soon after fertilization in some cases, and increasingly as time goes on, you may experience:. A pregnancy test is likely to produce an accurate result if a person takes it 1 week after the first day of the next expected period.

How Pregnancy Happens
Read More. Myths about the best timing and frequency of sex when trying to get pregnant can lead to unnecessary stress. Even when a couple is trying to conceive, they do not need to have sex every day and there is no need to drop everything and rush into bed at the exact moment of ovulation. Since sperm lives about two to three days inside the female reproductive tract, having sex two to three times a week is enough to result in pregnancy for most couples. For couples who prefer not to have intercourse that often, the key is to have the sperm waiting for the egg.

Your pregnancy at week 3
While you release only a single egg each month, your partner releases millions of sperm in a single ejaculation — all with their eye on that single prize. But only one of those sperm will be crowned the victor, and the odds are stacked against fertilization. Luckily, egg and sperm have developed some pretty nifty tricks to give themselves a fighting chance. Fortify the troops.
The SMEP method ensures you get that 1 in 4 shot by literally making sure the sperm and egg have every opportunity to meet each and every cycle. The timing of this is based on how long sperm live, realistically a few days under ideal conditions. Skip one day and give it one more try. Then the waiting begins… if your period has not arrived 15 days after your positive OPK, take a home pregnancy test. It may be tempting to test early, as some home pregnancy tests now can detect a positive as early as 8 days past ovulation.
The Magic That Happens When a Sperm Meets an Egg and the Sparks Fly
Achieving a healthy pregnancy is a complicated, multi-stage process involving two people. Every month, the female ovulates one mature egg from one of her ovaries. Here, it will begin to move slowly down the tube towards the womb uterus. However, for a pregnancy to develop it must first meet sperm from the male whilst it is still held in the fallopian tube. The sperm immediately begin swimming and some will find their way into the cervix.
