Pregnancy doesn't start the day you have sex — it can take up to six days after sex for the sperm and egg to join and form a fertilized egg. Then, it can take three to four days for the fertilized egg to completely implant itself in the lining of the uterus.

At this point, the newly fertilized egg is called an embryo. Within 24 hours after fertilization, the embryo divides into two cells. Soon it divides into four cells, then eight, and so on.

This period is generally divided into three stages: the germinal stage, the embryonic stage, and the fetal stage. The two-week period after conception is called the germinal stage. Conception occurs when a sperm cell combines with an egg cell to form a zygote.

Overview. Conception may take place as soon as three minutes after sexual intercourse, or it may take up to five days. Implantation occurs five to 10 days after fertilization, which means anywhere from five to 15 days after you had sex.

At a Glance Your soon-to-be fetus is still a cluster of cells that are growing and multiplying. It's about the size of a pinhead. It takes about four days for your fertilized egg — now dubbed a blastocyst — to reach your uterus and another two to three days to implant.

A zygote is a diploid cell resulting from the fusion of two haploid gametes, usually a sperm and egg. A zygote may not develop properly to become an embryo. An embryo is a collection of cells far enough along in its development that it quite possibly may become a fully developed entity.

Assuming everything aligns, conception—or when the egg is fertilized by the sperm—may take place as soon as three minutes after sex or it may take up to five days.

The zygote contains all of the genetic information (DNA) needed to become a baby. Half the DNA comes from the mother's egg and half from the father's sperm.

Meanwhile, implantation—or when the fertilized egg attaches to the uterine wall—occurs five to 10 days after fertilization, which means implantation can happen anywhere from five to 15 days after you had sex.

Conception is the moment when egg and sperm meet. It can take anything from 45 minutes to 12 hours for a sperm to reach your fallopian tubes, which is where conception usually happens.

In this article It can take anything from 45 minutes to 12 hours for a sperm to reach your fallopian tubes, which is where conception usually happens. However, sperm can survive inside your body for up to seven days , so conception can happen at any point in the week after sex, if you're ovulating.

At a Glance We have an embryo! Your soon-to-be fetus is still a cluster of cells that are growing and multiplying. It's about the size of a pinhead. It takes about four days for your fertilized egg — now dubbed a blastocyst — to reach your uterus and another two to three days to implant.

It will soon become an embryo. At 4 weeks, the blastocyst has made a 6-day trip from the fallopian tubes to the womb. Here, it begins to burrow or implant into the wall of the uterus.

Fertilization: When the sperm joins the egg and fertilizes it, conception takes place. Implantation: Seven to 14 days after sex, the fertilized egg attaches itself to the lining of the uterus.

Fetal Development: Stages of Growth. Within 24 hours after fertilization, the egg that will become your baby rapidly divides into many cells. By the eighth week of pregnancy, your baby will change names from an embryo to a fetus. There are about 40 weeks to a typical pregnancy.

The true statement is letter D. 1, 2 & 3. A zygote is the first cell of a new organism, a human zygote has 23 pairs of chromosomes 23 form the mother and 23 from the father and a zygote is produced through fertilization.
