In Vitro Fertilization
During in vitro fertilization eggs are extracted out of the woman’s ovary. The eggs are taken to the laboratory where, under strict laboratory conditions they are put in contact with the sperm of the husband.
After 2 or 3 days the fertilized eggs (now 4 or 8 cells embryos) are placed directly into the uterus to be implanted and proceed with the 9 months gestation.
Who Benefits from IVF?
What is the probability of getting pregnant using IVF?
IVF is used when:
- The Fallopian tubes are obstructed.
- There is a severe male factor.
- There is severe endometriosis.
- Other treatment options have failed.
When there is a severe male factor, alongside IVF, intracitoplasmic sperm injection [ICSI] is done to make sure that the egg is adequately fertilized.
The probability of getting pregnant using IVF for women under 35 years is above 45% with one treatment cycle. Factors that affect the probability are female age, duration of infertility and other fertility factors.
Cumulative pregnancy rates above 70% can be achieved after three treatment cycles.
