Adolescent girls without menstrual disorders formed the control group (n=50). A full clinical examination, hormonal analysis and thyroid and pelvic ultrasound examination were conducted. This study was carried out in accordance with the Helsinki Declaration.

In girls with dysmenorrhea in 1% cases was diagnosed hyperprolactinemia, in 20% – inflammation of genitals and in 30%- ovarian cysts. Among the girls with dysmenorrhea thyroid diseases (endemic goiter) were revealed in 73% cases. Oligomenorrhea was diagnosed in 22% adolescent girls and was associated in 80% cases with hirsutism. The investigation showed that in 5 girls with oligomenorrhea and hirsutism was diagnosed nonclassic congenital adrenal hyperplasia due to P450c21 (21-hydroxylase deficiency), 18 girls had polycystic ovary syndrome. Pelvic ultrasound examination established that 65% patients with oligomenorrhea and hirsutism had multifollicular ovaries. In the control group thyroid diseases (endemic goiter) was diagnosed in 20% adolescent girls, hirsutism – in 1% and multifollicular ovaries – in 8% girls (P<0.01)
