Question 1

What is the Meaning of Stress Mediated Infertility?

Accepted Answer

Stress Mediated Infertility describes the clinical condition where chronic psychological or physiological stress directly impairs reproductive capacity by disrupting the hypothalamic-pituitary-gonadal (HPG) axis. Sustained elevation of cortisol and other stress mediators inhibits the pulsatile release of Gonadotropin-Releasing Hormone (GnRH) from the hypothalamus. This suppression leads to a downstream reduction in Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH), which are essential for gamete maturation and sex hormone production. Addressing the underlying stress response is a primary therapeutic step to restore normal ovulatory and spermatogenic function.

Question 2

What is the Origin of Stress Mediated Infertility?

Accepted Answer

This concept is a long-recognized clinical entity rooted in the understanding of the HPA axis and its hierarchical dominance over the HPG axis, a phenomenon known as "stress-induced reproductive suppression." It reflects the body's ancient survival mechanism to prioritize immediate survival over reproduction during times of duress. The term formalizes the clinical link between allostatic load and reproductive dysfunction, validating the patient experience of stress impacting fertility. Modern endocrinology provides the precise molecular pathway for this observation.

Question 3

What is the Mechanism of Stress Mediated Infertility?

Accepted Answer

The primary mechanism involves the central inhibitory action of stress hormones and neuropeptides on the GnRH pulse generator in the hypothalamus. Elevated cortisol, often accompanied by increased GnIH activity, directly suppresses GnRH pulsatility. This reduced GnRH signal then causes the pituitary to decrease its output of LH and FSH. Consequently, the gonads receive insufficient stimulation, resulting in reduced sex hormone production and impaired folliculogenesis in women or spermatogenesis in men. Breaking the stress-HPA cycle is required to lift this central inhibition.
