Comparison of Hormonal and Metabolic Characteristics and Ovary Response to Induced Ovulation in Amenorrheic and Oligomenorrheic Women with PCOS

Objective To compare differences in endocrine and metabolic characteristics and response to induced ovulation treatment between oligomenorrheic and amenorrheic women with polycystic ovary syndrome (PCOS). Methods A total of 154 infertile PCOS patients presenting with oligomenorrhea or amenorrhea were retrospectively analysed, the differences in endocrine and metabolic characteristics and induced ovulation outcome parameters between oligomenorrheic and amenorrheic women were compared. Results Total follicle count, serum levels of total testosterone (TT), luteotropic hormone (LH) and insulin resistant index (HOMA-IR) were significantly higher in amenorrheic patients compared with oligomenorrheic patients (P Conclusions The degree of cycle irregularity might be a simple and effective clinical parameter to estimate the degree of metabolic and endocrine disorders and response to induced ovulation.
