Area of Science:

  • Reproductive Medicine
  • Medical Genetics
  • Obstetrics

Background:

  • Infertility affects numerous men whose sperm cannot fertilize eggs.
  • Genetic disorders pose risks for prospective parents.
  • Recurrent pregnancy loss (RPL) has identifiable causes, including trisomies and immunological issues.

Purpose of the Study:

  • To review recent technical advances in reproductive and genetic disorder diagnosis and treatment.
  • To highlight the potential of new technologies for preventing genetic diseases and improving pregnancy outcomes.
  • To address the underutilization of effective clinical methods.

Main Methods:

  • Intracytoplasmic sperm injection (ICSI) for male infertility.
  • Molecular genetic testing and preimplantation genetic testing (PGT) for genetic disease prevention.

  • Flow-cytometric sperm separation for X-linked disorders.
  • Maternal serum assays for trisomy detection.
  • Treatment protocols for immunological causes of RPL.

    • Main Results:

    • ICSI enables fertilization for previously infertile men.
    • Genetic testing and PGT significantly reduce the risk of affected offspring.
    • Flow-cytometry offers effective prevention of X-linked disorders.
    • 70% of RPL patients with immunological issues achieve live births with treatment.
    • Maternal serum assays improve trisomy detection accuracy.

    Conclusions:

    • Advances in reproductive medicine and genetics provide new diagnostic and therapeutic options.
    • These technologies offer significant benefits for infertile couples and those at risk of genetic disorders.
    • Wider clinical adoption of these safe and effective methods is needed to improve patient care.
