Let’s talk you through the journey of the egg to embryo.


Each month, one of the ovaries’ mature eggs is released. This process is referred to as ovulation. Ovulation occurs 2 weeks after the woman’s menstrual cycle has lasted.

 Moving to the fallopian tube

The egg released from the ovaries reaches the fallopian tube and there it will meet the sperm and will result in fertilization. 

Sperm journey

When a man ejaculates, around 40 to 150 million sperm are present in the fluid. Later they start swimming in the reproductive tract and move to the fallopian tube. The total time needed for the sperm to reach the egg is different and some of them might reach there in just 30 minutes and the rest of them can take days. Sperm can live there for 48 to 72 hours. The ones which reach close to the egg are just in hundreds. 

Fertilization: Sperm Penetrates Egg

Fertilization is completed within 24 hours. Once the sperm meets the egg the changes are made and this won’t let any other sperm come in.

 The Cells Start to Divide

Once the egg is fertilized, the division process begins. Following that, it will leave the fallopian tube and reach the uterus after 3 to 4 days. In some cases, it can result in ectopic or tubal pregnancy which happens when it does not enter the uterus.


Implantation is the method in which the egg is fertilized and then it is attached to the endometrium. Later, the fertilized eggs are going to divide.

 Pregnancy Hormones

Human chorionic gonadotropin (HCG) is one of the hormones which the cells produce and later they take the shape of the placenta. Its presence is in the mother’s blood and it can be checked within 2 weeks the women have conceived. The doctor will ask you to get a pregnancy test which is done through urine or blood tests.

 Fetal Development

Following the implantation, some of the cells take the shape of the placenta and some of them are formed as embryos. You can notice the heartbeat during the 5th week. In the 8th week, the embryo is developed and later forms the uterus. When the fetus reaches the 8th week it is constantly growing.
