08 Jan IVF Procedure Steps & FAQs
IVF PROCEDURE IN DETAIL
- Basic Investigations for both the male and female partners
- There are different protocols for ovarian stimulation (formation of eggs). Most protocols start with hormonal injections from day 2 or day 21 of the menses.
- These hormonal injections are advised for the total of 8-11 days depending on the response.
- Monitoring is done with serial ultrasounds (3-4 times) and sometimes blood tests.
- When the desired ovarian response is achieved, trigger injection is advised which has to be very strictly taken. This trigger is for the final egg maturation.
- Eggs are taken out of woman’s body under anesthesia using ultrasound guidance. Same time husband is asked to produce his sample in the laboratory.
- The embryologist mixes the eggs and sperms in special dishes and puts them for culture in specific conditions (incubators).
- After 2-5 days of culture, the embryos are inserted into the woman’s uterus (without anesthesia) under ultrasound guidance.
- The woman is advised medications to support the pregnancy for around 2 weeks after which the test to check for pregnancy is done (b-hcg).
Difference between IUI and IVF
IUI means intrauterine insemination of husband or donor semen (in certain cases) into the womb of a woman at the time of ovulation (release of egg from the ovary). In this procedure fertilization (fusion of egg and sperm) occurs inside the woman’s body. This is just like natural method of conception.
In IVF (in vitro fertilization), woman’s eggs are taken out of her body using ultrasound guidance and mixed with husband’s (or donor’s) sperm in the laboratory. Hence fertilization and embryos (future babies) formation happens outside the woman’s body. After a suitable time of 2-5 days, these embryos are directly inserted in the woman’s uterus. A number of steps of natural conception are bypassed in IVF technique.
Difference between IVF and surrogacy
In IVF the embryos formed (by fusion of egg and sperm of the couple) are transferred into the womb (uterus) of the genetic mother (who has contributed her eggs). However, in certain cases like absent uterus or diseased uterus, the embryos are transferred to the womb of another lady (third party: surrogate) who has not contributed her eggs and is not genetically related to the embryos. She carries the baby for 9 months and after delivery, hands over the baby to the genetic parents. The surrogate has no legal right over the resulting child.
