    Area of Science:

    • Reproductive Medicine
    • Human Embryology
    • Infertility Treatment

    Background:

    • Review of scientific and medical progress leading to clinical in vitro fertilization (IVF).
    • Description of current protocols for follicular stimulation and ovulation induction.

    Purpose of the Study:

    • To review the scientific and medical advances in human in vitro fertilization.
    • To discuss current clinical practices, success rates, and challenges in IVF.

    Main Methods:

    • Review of literature on follicular stimulants (clomiphene, human menopausal gonadotrophin) and ovulation triggers (LH surge, human chorionic gonadotrophin).
    • Analysis of multifolliculation, oocyte collection, and embryonic development in vitro (blastulation, zona pellucida hatching).
    • Examination of implantation factors, embryo typing, multipregnancy, and outcomes (abortion, live births).

    Main Results:

    • Current IVF methods utilize specific hormonal protocols for ovulation induction.
    • Embryonic development in vitro shows potential for blastulation and hatching.
    • Embryo implantation remains a significant challenge, influencing IVF success rates.

    Conclusions:

    • In vitro fertilization has advanced significantly, offering treatments for infertility.
    • Further research is needed to improve embryo implantation rates and optimize IVF outcomes.
    • Techniques like embryo cryopreservation and immature oocyte use are briefly mentioned.
