Aim. Study of the relative telomere lengths in women with a history of early reproductive losses. Methods. Relative Telomere Length (RTL) was studied in the peripheral blood lymphocytes using a real time polymerase chain reaction (RT-PCR). Results. RTL was studied in 281 women, among which 169 - with early reproductive losses (ERL) (surveyed group) and 112 - have healthy children and no reproductive losses in history (control group). For women under the age of 35, the average RTL value is significantly higher than that of older women, P = 0.003597. In women with ERL, RTL is significantly lower than that of women with a preserved reproductive function, P = 0.0000001. The value of RTL is significantly lower in women with ERL under 35 years compared with control, P = 0.0000001, and is similar to value of RTL in women in the control group at the age of 36, P> 0.05. Conclusions. The telomere lengths is significantly lower in both older women and women with ERL. The similarity of RTLvalue in women with ERL up to 35 years of age and in women with a preserved reproductive function at the age of 36 years testifies to the

telomeric theory of reproductive aging.
