IVF or In Vitro Fertilization is a process in which an egg is fertilized by a sperm outside the body. This treatment option is for those in whom all other methods of assistive reproductive techniques have failed. Woman's natural cycle is monitored to collect eggs for fertilization. The eggs are fertilized with human sperms in a controlled environment and the fertilized egg is planted in the patient's uterus to obtain a successful pregnancy. If the first cycle of IVF does not succeed there could be a few more IVF cycles performed to achieve sustainable pregnancy. At times, the patient's body does not retain pregnancy then a surrogate mother could be sought, who bears the egg of the patient fertilized by her partner's sperm. Surrogacy is an arrangement between a woman and a couple or individual to carry and deliver a baby. Women or couples who choose surrogacy often do so because they are unable to conceive due to a missing or abnormal uterus, have experienced multiple pregnancy losses, or have had multiple in vitro fertilization attempts that have failed. The advantage of gestational surrogacy to the parents is that the embryo is created from the woman's egg and the man's sperm, so it is biologically theirs. The patient's family along with them can bring a surrogate mother OR more popularly a surrogate is taken from the place of treatment. The success rate of IVF treatment usually varies between 40-60%, however these are just estimates. The doctor can only give a closer estimate after physical examination.
