What is third party reproduction?third party reproduction in laymans terms means taking the help of a third person by a couple for the process of ivf. The most common ways it can be done is by using donor eggs, donor sperms, donor embryos or by surrogacy. Who needs third party reproduction?as more and more couples are delaying marriage and childbirth, there is an increasing trend toward third party reproduction being seen in recent years. Donor eggs - one of the most common reason for the need of donor egg is advanced age. As the couples waste their precious reproductive years moving from doctor to doctor trying to conceive naturally, by the time they are seen by a reproductive specialist, they already have low ovarian reserve or poor amh results. Also there might be poor number of eggs due to previous ovarian surgery for endometriosis , cystectomy or even drilling. In certain patients there might be need for donor eggs due to poor egg quality in previous ivf cycles. Donor sperms : there is a considerable increase in the number of cases of male infertility. The need for donor sperms is there only when in an azoospermic (no sperms) male , the doctor has not been able to retrieve any sperms by the process of testicular sperm extraction or tese donor embryos : it is like adoption and may only be indicated when there are both male and female factors or due to financial constraints. Surrogacy : in simple terms means renting a womb or taking the help of another womans womb to carry ones child. It might be needed in patients with uterine abnormalities like fibroid, adenomyosis, unicornuate uterus etc; in patients with recurrent ivf failures or if a pregnancy is dangerous for maternal health.
