A surrogate mother should not be over 45 years of age. Before accepting a woman as a possible surrogate for a particular couple’s child, the ART clinic must ensure (and put on record) that the woman satisfies all treatable criteria to go through a successful full-term pregnancy.
In Indian context, a known person as well as a person unknown to the couple may act as a surrogate mother. In case of a relative acting as a surrogate mother, she should belong to the same generation as the woman desiring the surrogate.
No woman may act as a surrogate more than thrice in her lifetime.
