Some of the new trends in fertility treatment include vitrification, preimplantation genetic testing (PGT), and the freeze-all strategy. Vitrification is a fast freezing method that preserves embryos and eggs for years. PGT helps choose genetically healthy embryos for transfer, improving pregnancy rates and reducing the risk of miscarriage. The freeze-all strategy combines vitrification, IVF, and PGT to optimize timing and reduce the risk of ovarian hyperstimulation syndrome.
