On the basis of your infertility issue, you may adopt one of the following options:
Where female partner gets unable to produce eggs, then surrogate eggs get combined with the intended father’s sperm in laboratory, and again transferred into the uterus of the surrogate who takes child until the delivery, known as traditional surrogacy;
When due to some reasons, female partner cannot conceive pregnancy to its full term, even when she is able to produce eggs. In this case, ovum and sperm are removed from the couples and are combined to make embryos which then moved into the surrogate uterus for further growth, known as gestational surrogacy;
Another case comes in vision where not the intended mother’s ovum and not the intended father’s sperm are used to get the pregnancy one or both may be obtained from a donor. In this, intended parents are not biologically connected to the child, unless when the intended father’s sperm gets used to consider pregnancy.
