In the context of In Vitro Fertilization (IVF) Treatment segmentation, the market is principally divided by application. The dominant Primary infertility treatment segment accounts for roughly 55 % of total revenue, reflecting the widespread demand for assisted conception among couples with unexplained, male, or female factor infertility. Preimplantation Genetic Testing (PGT) integration represents about 20 % of the market; clinics combine IVF cycles with PGT to screen embryos for chromosomal abnormalities, thereby commanding higher procedural fees and driving incremental growth. Egg and sperm donation services contribute an estimated 10 % as patients unable to provide viable gametes turn to donor programs, which require specialized sourcing and legal compliance. Embryo cryopreservation also captures 10 % of market value, given its role in preserving surplus embryos for future transfer, a practice that extends the life‑cycle revenue of each IVF cycle. Finally, Surrogacy support—including legal, medical, and coordination services—makes up the remaining 5 %, a niche but high‑margin segment. Collectively, these application categories shape the overall market size and inform strategic investment decisions.
