Changes of serum thyroid hormone levels in patients with polycystic ovary syndrome induced by ovulation disorder / 中国综合临床

ABSTRACT

Objective To analyze the relationship and significance between plasma level of thyroid hormone and ovulation disorder of (polycystic ovary syndrome)PCOS.Methods Eighty-nine cases with PCOS were induced ovulation by CC+HCG.During menstrual cycle of induced ovulation,PCOS patients were divided into two groups according to Ovulation (No ovulation 40,ovulation 49).The level of thyroid hormone at different follicular development period and ovulatory time were detected.Result Levels of thyroid hormone at two groups were no difference at 5 mm,10 mm,15 mm size follicular phase(P＞0.05).But there was significant at follicular 20mm size(F inner groups=4.38,50.34,48.65;P＜0.05).The level of T3 an T4 at No ovulation group was lower than those in ovulation group(T3(2.69±0.15) nmol/L vs.(1.97±0.17) nmol/L;T4(124.38±0.29) nmol/L vs.(97.43±0.16) nmol/L).The level of TSH at No ovulation group was (3.43±0.10) mU/L,higher than that in ovulation group ((1.38 ± 0.18) mU/L;P ＜ 0.05).Conclusion The level of thyroid hormone in patients of ovulation group is at a normal level when the follicle is mature,and the level of thyroid hormone can affect the normal ovulation of patients with PCOS.
