Аннотация

Проведен анализ результатов спермиологического исследования у 200 мужчин с бесплодием, имеющих различное количество СAG-повторов в экзоне 1 гена андрогенового рецептора (AR). Число повторов варьировало от 7 до 31, в среднем оно составило 22,2 ± 1,6, а наиболее часто встречающимся вариантом (13 %) был 21 повтор. Полученные данные свидетельствуют об определенном влиянии CAG-полиморфизма гена AR на показатели сперматозоидов у мужчин, а также о том, что нарушение сперматогенеза у носителей «коротких» последовательностей CAG-повторов может иметь не менее выраженный характер, чем у носителей «длинных» CAG-аллелей.

Abstract

We analyzed the results of semen examination in 200 infertile men with various numbers of GAG-repeats in the exon 1 of the androgen receptor (AR) gene. The number of repeats ranged from 7 to 31, the average number of repeats was 22.2 ± 1.6, with the most common variant (13 %) present 21 repeats. Our findings confirm that of AR gene СAG-polymorphism can an effect on sperm parameters and male fertility. The spermatogenesis can be impaired in infertile men with “short” CAG-repeats not less than with “long” CAG-repeats.
