目的观察不孕症患者在自然周期中优势卵泡生长和排卵的特点。方法回顾性总结分析2014年3月至2014年12月125例不孕症患者在自然周期中经阴道超声行卵泡监测的临床资料。结果优势卵泡排卵发生在月经周期第11~20天,平均14.85±2.47天。3例患者出现未破裂卵泡黄素化综合征,发生率为2.40%。排卵前优势卵泡直径为15.50~27.00mm,平均直径为19.05±1.43mm。14例患者怀孕,妊娠率为11.20%(14/125)。妊娠者和未妊娠者排卵前优势卵泡直径和排卵时间的差异均无统计学意义(P>0.05)。结论采用经阴道B超观察自然周期优势卵泡生长和排卵特点为不孕患者的诊治提供了很好的参考价值。
Objective To observe the characteristics of follicles growth and ovulation in infertility patients during the natural cycle. Methods The clinical data of 125 patients with infertility who underwent transvaginal ultrasound in follicular monitoring from March 2014 to December 2014 were analyzed retrospectively. Results The dominant ovulation took place on the 11th to 20th days of the menstrual cycle with an average of 14.85 ± 2.47 days. 3 cases of patients with unruptured follicular luteinizing syndrome, the incidence was 2.40%. The dominant ovulation follicle diameter before ovulation 15.50 ~ 27.00mm, the average diameter of 19.05 ± 1.43mm. Fourteen patients were pregnant with a pregnancy rate of 11.20% (14/125). There was no significant difference in the diameter of ovulation predominant ovum and ovulation time between pregnants and nonpregnant women (P> 0.05). Conclusions Transvaginal ultrasonography was used to observe the growth and ovulation characteristics of dominant follicles in the natural cycle, which provided a good reference value for diagnosis and treatment of infertility patients.
