These innovations have revolutionized the field of reproductive healthcare by providing remedies for infertility, genetic conditions and other barriers for conception. Following are the different types of NRTs available:
1. In Vitro Fertilization (IVF): In Vitro Fertilization (IVF) is a pivotal advancement in reproductive technology, offering hope to couples encountering infertility challenges. The procedure commences with ovarian stimulation through hormonal medications aimed at promoting the production of multiple eggs. Following this, eggs are retrieved using a minimally invasive surgical procedure involving a needle guided by ultrasound. Once collected, these eggs undergo fertilization in a laboratory, either through conventional mixing with sperm or via Intracytoplasmic Sperm Injection (ICSI) for severe male infertility cases. The resultant embryos are cultured for several days and carefully assessed for quality. Subsequently, the most viable embryos are chosen for transfer into the woman’s uterus, with the goal of achieving a successful pregnancy.
2. Intracytoplasmic Sperm Injection (ICSI): Intracytoplasmic Sperm Injection (ICSI) is a specialized procedure within the realm of IVF intended to tackle severe male infertility issues. It involves the precise injection of a single sperm directly into an egg to facilitate fertilization. This technique proves highly advantageous in cases where sperm count, motility or morphology pose hindrances to natural fertilization. The process begins similarly to standard IVF with ovarian stimulation and egg retrieval. However, instead of combining eggs and sperm in a dish, an embryologist individually selects a healthy sperm and injects it into each mature egg using a delicate needle. This direct approach significantly enhances the likelihood of fertilization, particularly in scenarios where conventional methods fall short.
3. Preimplantation Genetic Testing (PGT): Preimplantation Genetic Testing (PGT) is a valuable technology used in conjunction with in-vitro fertilization (IVF) to screen embryos before they are implanted into the uterus. It enables the detection of genetic abnormalities, allowing selection of the healthiest embryos for implantation. PGT comes in various forms: PGT-A targets chromosomal abnormalities (aneuploidies), PGT-M focuses on single-gene defects such as cystic fibrosis and PGT-SR identifies structural rearrangements in chromosomes like translocations. By identifying embryos with the correct chromosome count or without specific genetic disorders, PGT helps minimize the risk of miscarriages and genetic diseases, enhancing the chances of a successful pregnancy and providing reassurance to prospective parents.
4. Cryopreservation: Cryopreservation involves freezing and storing reproductive cells like sperm, eggs or embryos for later use. This technology provides flexibility and assurance for individuals and couples who are not ready to start a family immediately or are undergoing medical treatments like chemotherapy that could impact their fertility. Egg freezing allows women to preserve their fertility for future use, which is beneficial for those choosing to postpone childbirth due to personal or professional reasons.
