If all viable embryos are of the non-preferred sex, patients can transfer a healthy embryo regardless of sex, cryopreserve them for future use, or donate them. Thailand clinics using PGT-A testing identify chromosomal sex with nearly 100% accuracy but cannot control biological production ratios.
- Success strategy: Doctors recommend retrieving 15–20 eggs to increase the probability of preferred-sex embryos.
- Financial relief: Some clinics offer partial PGT-A refunds or discounts on a second cycle.
- Alternate paths: Repeating the IVF cycle or using donor gametes can improve selection odds.
- Clinical options: Embryos can be donated to other couples or discarded as medical waste.
Bookimed Expert Insight: Thai clinics like Prime Fertility Clinic maintain high standards as JCI-accredited facilities, yet biology remains unpredictable. Data shows that even with 10+ embryos, some cycles yield 100% of one sex. Before paying $12,000, always request a written policy on reduced fees for a second stimulation cycle if no preferred-sex embryos are found.
Patient Consensus: Many patients report an emotional toll when selection fails but often find deeper joy than expected after transferring a healthy `surprise` embryo. It is common for clinics to pivot to the blessing of a healthy pregnancy once biological results contradict pre-cycle preferences.
