Despite extensive research in fertility and in vitro fertilization (IVF), more than half of embryos transferred during IVF cycles fail to implant. The success or failure of implantation depends on multiple factors, some of which are still unknown.

Studies indicate that embryo factors account for roughly one-third of implantation success, while maternal factors account for the remaining two-thirds. Even in natural conception, couples face a 20 – 25% chance of successful pregnancy per cycle, and in approximately 50% of cases, natural conception ends in miscarriage, often without the mother realizing it.

 This underscores that implantation is not a guaranteed process. For couples experiencing repeated implantation failure, the embryo’s role becomes even more critical.

At Pooyesh Fertility Clinic, embryos are selected carefully and transferred at the optimal stage to maximize the chances of implantation. For patients with a history of implantation failure, several advanced strategies are employed, including:

• Blastocyst-stage embryo transfer to improve implantation potential.
• Time-lapse imaging to monitor embryo development and select the most viable embryo.
• Advanced sperm selection techniques to ensure the highest quality sperm is used.
• The embryo’s outer layer is gently opened to improve implantation.
• Embryos are tested for genetic problems before transfer.

• Methods for gender selection and their success rates
• Overview of infertility treatments and answering patient questions
• Preimplantation genetic testing (PGT) and gender selection using PGT
• Spermogram and TUNEL test results, with treatment recommendations
