What is IVF?
Normally an egg is fertilized by the sperm inside the woman’s body, but if due to some reasons fertilization does not occur, then IVF is done. In vitro fertilization is the process in which an egg is fertilized by the sperm outside the body. It is a complex procedure used in the treatment of fertility or genetic problems. The mature eggs are collected from the woman’s ovary and fertilized by the sperm in the laboratory, and then this fertilized egg is implanted in the uterus.
It is the most effective form of assisted reproductive technology. The procedure is done using your own eggs and partner’s sperm or the eggs and sperms from the unknown donor.
Indications for IVF
- Low sperm count
- Problems with fallopian tubes and uterus
- Ovulation does not take place
- The inability of sperms to penetrate and survive in the cervical mucus
Procedure of IVF
The procedure is undertaken by IVF treatment clinics in Chandigarh under strict supervision of skilled doctors. IVF process involves
Stimulating multiple follicles and eggs or superovulation
Fertility medicines are given to women to boost egg production, the follicle growth is monitored with the help of regular transvaginal ultrasounds and blood tests to check hormones level.
When follicles are mature enough to produce eggs, HCG is given and within a period of 30-36 hours, the eggs are retrieved. The retrieval method includes follicular aspiration and laparoscopy.
Insemination and fertilization
The sperms are placed together with the best quality eggs; this mixing of sperms with the eggs is known as insemination.
Eggs and sperms are incubated in culture medium for proper maturation. The sperms fertilize the eggs within 24 hours.
When the fertilized egg divides an embryo is formed; it is checked regularly for proper growth. Within 5 days the embryo has several actively dividing cells.
Embryos are placed into the woman’s uterus for normal growth. The doctor inserts a thin tube containing embryos into the vagina, through cervix all the way to the uterus.
Success rate of IVF
Success rate of IVF varies from patient to patient as it depends on following factors.
- Age of the woman
- Success or failure rate of fertilization and cleavage in IVF
- Number of mature eggs retrieved
- Total number of eggs transferred
- Actual causes of infertility
The doctors at Mohali and Chandigarh IVF Centres, say that success rate increases with the increase in IVF stimulation attempts.
