First Weeks of Pregnancy
From Articles by Melanie Wade
Fertilization of the Egg
When the sperm and egg join, the sperm must pass through several outer layers of the ovum, although many sperm penetrate the outer layers usually only one sperm enters the ovum and fertilizes it. After the sperm penetrates the ovum, the sperm head attaches to its surface. The membranes of the sperm and ovum unite, enclosing in the same membrane. The sperm also loses its tail. The head of the sperm is called the male pro nucleus, the ovum is called the female pro nucleus. Each parent supplies 23 chromosomes your baby is a combination of chromosomal information from both parents. Your baby’s sex is determined at the time of fertilization by the type of sperm that fertilizes the egg.
Calculating a pregnancy this way gives the gestational age or menstrual age, most doctors and midwifes use this method to keep track of time during pregnancy. Most people count time during pregnancy by using weeks, most find this the easiest way.
Its also important to understand a due date is only an estimate, not an exact date don’t count on that particular date, see it as a goal a date to prepare and look forward to, you may see that date come and go and no baby.
