What is the Origin of IVF Protocols?

The development of IVF protocols began following the first successful human IVF birth in 1978, moving from natural cycles to the use of exogenous gonadotropins to increase efficiency. The subsequent introduction of GnRH agonists and antagonists to prevent premature luteinizing hormone surges led to the establishment of the modern long, short, and antagonist protocols. These protocols are the cornerstone of contemporary reproductive endocrinology practice.

What is the Mechanism of IVF Protocols?

The primary mechanism involves the controlled administration of Follicle-Stimulating Hormone (FSH) and Luteinizing Hormone (LH) analogs to stimulate the synchronous growth of a cohort of ovarian follicles, overriding the natural single-dominant follicle selection. Simultaneously, Gonadotropin-Releasing Hormone (GnRH) agonists or antagonists are employed to temporarily suppress the pituitary's release of endogenous LH. This suppression prevents an untimely surge that would trigger premature ovulation and compromise the retrieval of the eggs at the optimal time.

IVF Protocols

Meaning

IVF Protocols refer to the standardized, sequential regimens of hormonal medications and clinical procedures used to manage the ovarian stimulation phase of In Vitro Fertilization (IVF) treatment cycles. These protocols are meticulously designed to control the timing of follicular development, prevent premature ovulation, and optimize the retrieval of multiple mature oocytes for subsequent fertilization. The choice of protocol is highly individualized, depending on the patient’s ovarian reserve, age, and clinical history.
