They were studied retrospectively through their records. 35.1% of the studied group had had natural spontaneous pregnancy, 9.0 % - following induced ovulation, 51.9 % - due to implemented technique of in-vitro fertilization through embryo transfer, 4.5% - due in-vitro fertilization though intra-cyto-plasmatic sperm injection, one woman of 43 years had had oocyte donation. So, two study groups were created: women with natural spontaneous pregnancy and women with induced pregnancy. Medical social features were of observed pregnant women were studied.

The state of menstrual function was also a significant factor: in women with induced pregnancy oligomenorrhea occurred significantly frequently than in women with spontaneous natural pregnancy.
