Objective:
To assess the autonomic system in patients with polycystic ovary syndrome (PCOS).
Materials And Methods:
Thirty-seven adult patients with PCOS and 33 healthy controls were enrolled in the study. The electrophysiological assessments of the autonomic nervous system function were performed using sympathetic skin response and R-R interval variation tests.
Results:
The mean latency of sympathetic skin response in PCOS patients was significantly delayed compared with the controls (p = 0.001). The mean amplitude of sympathetic skin response was significantly lower in comparison with the controls (p = 0.01). Mean R-R interval variation during deep breathing was also significantly delayed (p = 0.04).
Conclusion:
There are parasympathetic dysfunction and sympathetic dysfunction in patients with PCOS. This may be easily demonstrated with sympathetic skin response and R-R interval variation tests.

Adrenal Gland Disorders
Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss.

Hormonal Control of the Ovarian Cycle
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...
