30岁的王女士在一家外企工作。她平时身体很好，没有什么症状，但是怀孕半年了。她去做检查了。医生告诉她，怀孕困难是因为她甲状腺功能降低。甲减也会导致不孕吗？

据统计，约有2.5%的孕妇患有甲减，“亚临床甲减”者高达6%。但由于亚临床甲减介于健康和疾病之间，往往无症状，容易被忽视，导致问题加重。今天就来说说甲减到底是怎么回事吧！

什么是甲减？

简单来说，甲状腺激素合成分泌过少导致代谢活性降低

甲减的小伙伴往往怕冷、口齿不清、表情淡漠、乏力、唇厚舌薄、食欲不振、腹胀便秘、心动过缓、记忆力减退、性欲减退等。

孕妇甲状腺功能减退会直接影响胎儿神经系统的正常发育，导致胎儿智力低下，出生后智力水平低下，如痴呆。

一般来说，甲减女性比男性多见。20~40岁女性甲状腺功能减退症发病率约为2%~4%，尤其是40岁以上女性，患病率随年龄增长而增加。研究发现，不孕患者中甲状腺功能减退的患病率显著增加。

甲减对怀孕有什么影响？

1。导致不育

患有甲减的蘑菇往往容易出现月经不调、月经过多或闭经、排卵障碍和卵巢萎缩。

男性伴侣容易出现精子数量减少、形态异常、精子活力下降等现象。此外，甲状腺功能减退引起的性欲减退、性生活不满意也是不孕的间接原因。

2。伤害胎儿
