In vitro fertilization (IVF) is a kind of pregnancy mode in which multiple IVF embryos are transferred into women's uterus to increase the chance of pregnancy. The calculation method of IVF pregnancy week is different from that of natural pregnancy. This article will elaborate on the definition of gestational week, calculation of gestational week of IVF, relevant medical institutions and precautions.

definition

Gestational week refers to the time from the beginning of pregnancy to the present, usually based on the first day of the last menstruation at the time of pregnancy. The definition of pregnancy week of IVF is similar to that of natural pregnancy, but the calculation method is slightly different.

Calculation method of natural pregnancy weeks

The calculation method of pregnancy week of natural pregnancy is simple and direct: Day 1: The first day of the last menstruation, marked as the beginning of pregnancy. Day 14: The egg matures in the ovary, which is usually the day of ovulation. Day 21: After the fertilized eggs are implanted, pregnant women can conduct urine pregnancy test. Day 28: the first day of the menstrual cycle. If a pregnant woman is pregnant, she can detect progesterone through urine or blood.

Calculation of gestational weeks of test tube infants

Since IVF is implanted into the uterus after fertilization and embryo culture in the laboratory, the calculation method of pregnancy week is slightly different. Day 1: The day of fertilized egg transfer is the beginning of pregnancy. Day 14: progesterone test was performed to determine whether there was pregnancy. The calculation method of gestational week after fertilized egg transplantation is the same as that of natural pregnancy.
