Fetus
The growth and development of the fetus every day in the womb of the mother and the process of fetal development This is an amazing process, where ovulation begins two weeks before the date of the menstrual cycle and begins pregnancy in Achroom of the menstrual cycle and this is called (the age of menstruation), after the occurrence of ovulation is increasing hormone secretion progesterone and estrogen, Progesterone helps to prepare the lining of the uterus so that the fetus attaches to the uterine wall when the sperm penetrates the egg.
If the sperm is the semen that fertilizes the egg, it means that your child will be male. If the sperm is the sperm fertilizing the egg, your child will be female. Within 24 hours after the fertilization process, The egg is slowly passed through the fallopian tube to the uterus. The fertilized egg attaches to the lining of the uterus. This stage is called the implantation. The hormones that are secreted help the egg to attach to the uterus. As for the stages of fetal development in his mother’s womb, this will be discussed later.
