Surrogacy in California

Embryo readiness is a crucial step in California surrogacy. Ensuring embryos are healthy and viable increases the chances of a successful pregnancy. Intended parents, surrogates, and fertility specialists must work together closely during this phase.

Surrogacy in California guides intended parents through every step, from genetic testing to embryo transfer, ensuring the highest standards of safety and success.

The Role of PGT-A Testing in Embryo Health and Success

1. PGT-A: Genetic Testing for Embryos

PGT-A (Preimplantation Genetic Testing for Aneuploidy) is now standard in many California IVF clinics.

  • It screens embryos for chromosomal abnormalities.
  • Helps select the healthiest embryos for transfer.
  • Reduces the risk of miscarriage and increases success rates.

PGT-A is particularly important for older intended parents or those with a history of IVF failures. Agencies like Surrogacy4All coordinate testing with trusted fertility clinics to ensure accuracy.

2. Vitrification: Freezing Embryos Safely

Vitrification is an advanced embryo freezing technique used in California surrogacy.

  • It rapidly freezes embryos to prevent ice crystal formation.
  • Preserves embryo viability for future transfers.
  • Allows flexibility in timing, especially for surrogate and intended parent schedules.

Vitrified embryos can be stored safely until the surrogate is ready for transfer. This process also supports multiple IVF cycles if the first attempt is unsuccessful.

3. FDA-Certified Labs

Embryo handling must follow strict quality standards. FDA-certified laboratories in California ensure:

  • Safe handling and storage of embryos
  • Accurate testing results, including PGT-A
  • Compliance with federal regulations for assisted reproductive technologies

Using FDA-certified labs reduces risks during IVF surrogacy, ensuring the highest chance of a successful pregnancy.

4. Coordinating Between Clinics and Agencies

A seamless surrogacy journey requires close coordination. Surrogacy4All works with fertility clinics, labs, and intended parents to:

  • Schedule embryo testing and freezing
  • Ensure timely embryo transfer
  • Monitor embryo health and readiness
  • Provide clear updates to intended parents

This level of coordination minimizes delays and maximizes the chances of success.

5. Tips for Intended Parents

  • Ask your agency about PGT-A and vitrification options.
  • Confirm the lab is FDA-certified for safety and compliance.
  • Plan embryo transfer according to the surrogate’s medical readiness.
  • Maintain communication with your agency for updates and guidance.
