What is the Meaning of Ovarian Hyperstimulation Syndrome?

Ovarian Hyperstimulation Syndrome (OHSS) is an iatrogenic, potentially serious complication resulting from an excessive, adverse response to ovarian stimulation, typically encountered during fertility treatments involving exogenous gonadotropins or other ovulation-inducing agents. The syndrome is clinically characterized by massively enlarged ovaries, accumulation of fluid in the abdomen (ascites), and in severe cases, dangerous hemoconcentration and thromboembolic events. It represents an acute, systemic inflammatory and vascular reaction to pharmacological endocrine manipulation.

What is the Origin of Ovarian Hyperstimulation Syndrome?

The condition was first recognized and clinically described following the introduction of exogenous gonadotropin therapy in the 1960s as a treatment for anovulation and infertility. As assisted reproductive technologies (ART) became more prevalent, the incidence of OHSS emerged as a significant clinical challenge, necessitating the development of strict monitoring protocols and safer, more controlled ovarian stimulation regimens. Its origin is intrinsically linked to the history of pharmacological intervention in the female reproductive endocrine system.

What is the Mechanism of Ovarian Hyperstimulation Syndrome?

The underlying mechanism involves the massive, local release of vasoactive substances, predominantly Vascular Endothelial Growth Factor (VEGF), from the hyperstimulated ovaries, which drastically increases capillary permeability throughout the body. This systemic leakage of fluid from the vascular space into the third space, such as the peritoneal cavity, leads to ascites, hemoconcentration, and subsequent electrolyte imbalance. The acute hormonal surge, particularly the human chorionic gonadotropin (hCG) trigger, is the critical event that initiates this cascade of severe systemic vascular dysfunction.
