The role of stress in reproduction, particularly during treatment for infertility, has been of considerable interest; however, few studies have objectively measured stress and anxiety over the course of the IVF cycle or compared the experience of first-time and repeat patients.
This prospective cohort pilot study enrolled 44 women undergoing IVF at a university-based clinic to complete the State-Trait Anxiety Inventory (STAI), Perceived Stress Scale (PSS) and Infertility Self-Efficacy Scale (ISES) at three time points prior to ovarian stimulation (T1), one day prior to oocyte retrieval (T2), and 5-7 days post embryo transfer (T3).
Mean STAI State scores were significantly elevated at all three time points (p<0.01). STAI State and PSS mean values did not change over time and did not differ in first-time vs. repeat patients. Self-efficacy (ISES) scores declined over time, with a greater decline for repeat patients. Of the 36 women who completed a cycle, 15 achieved clinical pregnancy. Using logistic regression modeling, all scores at T2 were correlated with pregnancy outcome with lower scores on the STAI State and PSS and higher scores on the ISES associated with higher pregnancy rates.
Stress and anxiety levels remained elevated across all cycles. Women with lower stress and anxiety levels on the day prior to oocyte retrieval had a higher pregnancy rate. These results emphasize the need to investigate stress reduction modalities throughout the IVF cycle.
压力在生殖中的作用,尤其是在不孕治疗期间,一直引起了相当大的关注;然而,很少有研究在整个体外受精(IVF)周期中客观地测量压力和焦虑,也很少有研究比较首次和重复患者的经历。
这项前瞻性队列试点研究纳入了 44 名在大学附属医院接受 IVF 的女性,要求她们在卵巢刺激前(T1)、取卵前一天(T2)和胚胎移植后 5-7 天(T3)三个时间点完成状态-特质焦虑量表(STAI)、压力感知量表(PSS)和不孕症自我效能量表(ISES)。
STAI 状态评分在所有三个时间点均显著升高(p<0.01)。STAI 状态和 PSS 的平均值随时间没有变化,在首次和重复患者中也没有差异。自我效能感(ISES)评分随时间下降,重复患者的下降幅度更大。在完成一个周期的 36 名女性中,有 15 名获得了临床妊娠。使用逻辑回归模型,T2 时的所有评分都与妊娠结局相关,STAI 状态和 PSS 评分较低,ISES 评分较高与较高的妊娠率相关。
所有周期的压力和焦虑水平仍然升高。在取卵前一天压力和焦虑水平较低的女性妊娠率较高。这些结果强调了在整个 IVF 周期中需要研究减压方法。
