While 2007 figures from the Society for Assisted Reproductive Technology reported 276 successful gestational surrogate pregnancies in the U.S. (with the patient's oocytes), India's clinics likely delivered 150 successful gestational pregnancies (with both patient's and donor oocytes). This makes India the second most common location for gestational surrogacy. However India, unlike the U.S. and Europe, has clinics that specialize in gestational surrogacy.
Each Indian clinic provides support for different types of surrogacy, with many support all types of surrogacy including:
- Traditional: Oocytes (eggs) from a donor are retreived using traditional IVF-ET techniques, are fertilized from the husband's sperm and placed in the recipients uterus. In traditional surrogacy, the recipient is the mother that will raise the child.
- Gestational: Oocytes (eggs) from the biological mother are retrieved using traditional IVF-ET techniques, are fertilized with the husband's sperm, and are placed in the carrier's uterus. The carrier is also known as the gestational surrogate.
- Gestational with egg donor: This is very common for gay male couples, as they seek both a gestational surrogate and an egg donor.
For cycles with gestational carriers using patient's oocytes, SART figures for clinics in the U.S. show that fresh cycles in 2007 had the following results:
- 48% of cycles resulted in live births for women less than 35 years old
- 41% of cycles resulted in live births for women 35 to 37 years old
- 23% of cycles resulted in live births for women 38 to 40 years old
- 19% of cycles resulted in live births for women greater than 40 years old
Of these cycles, 30% had twins, and almost 3% had triplets or more.
Oocytes from younger women possess greater fertility potential, so if you are using a donor egg, the donor's age is one of the most significant factors for a successful birth.
Clinics in India have not yet published such specific results, but individual clinics do claim success rates close to 50% (although it is difficult to verify these claims). A summary of clinics, the number of births, and their claimed success rates, is included as part of the clinics overview.
