Our results suggest secondary to insulin resistance and hyperandrogenism impairment of hormonal stroma adipose tissue function in PCOS, independent of nutritional status. Contrarily, the adipocyte hormonal dysfunction is primarily dependent on excessive fat accumulation. It seems that the AOR may be useful in the assessment of adipose tissue dysfunction not only in PCOS.

Nutritional status seems to have different effects on apelin release, particularly, its active isoform, in women with PCOS compared with women without PCOS. This may be partially caused by changes in leptin and resistin secretion and may enhance pituitary-ovarian axis disturbances. The association between both isoforms of apelin and insulin resistance seems to be bidirectional.

In this observational study, nutritional status appears to be the main factor influencing circulating AMH levels independent of PCOS. The observed AMH association with omentin-1 levels suggests that this adipokine may be a link between hormonal dysfunction of adipose tissue related to obesity and decreased AMH secretion.

Anovulatory cycles and endometriosis are the main causes of female infertility. The most frequently anovulatory cycles are related to polycystic ovary syndrome (PCOS) commonly associated with obesity and hormonal disturbances in the course of obesity. Recently published studies revealed that infertility affects about one in six couples during their lifetime and is more frequent in obese. Obesity is also associated with male infertility related to erectile dysfunction, hormonal disturbances and lower semen quality. Any of these above mentioned disorder is the important risk factor of psychological disturbances and poor quality of life among women and men in the reproductive age. On the other hand the mood disorders may exacerbate the hormonal disturbances and worsen the effectiveness of infertility management. Infertility, its therapy with accompanying psychological disturbances may also significantly affect the partners relationships. The review summarize the results described in the current literature on the association between obesity and infertility and psychological disturbances as well as their impact on quality of life and sexual functioning in women and men. Moreover, the impact of infertility and psychological disturbances on partners relationships is discussed.

The results of our study suggest that testosterone increases expression of 5-alpha-reductase types 1 and 2 in dermal papillae from the lower abdominal region in patients with hirsutism.
