Sexual frigidity after giving birth to a child is mainly considered to be related to endocrine disorders, post-partum depression or the effects of physical illness, and insufficient communication of the couple’s sexual needs. In addition, the possibility of other factors such as high work pressure and the influence of drugs should also be considered. 1. Endocrine disorders: after giving birth, women may experience endocrine disorders and trigger hypogonadism, resulting in frigidity. 2. Disease effects: Postpartum depression can lead to symptoms of frigidity, as well as significant emotional depression. In addition, women’s resistance is relatively poor in the postpartum period, and cardiovascular and cerebrovascular diseases, gynecological diseases, and central nervous system disorders may occur, which may also cause frigidity. 3. Insufficient communication between husband and wife in terms of sexual needs: During pregnancy and postpartum recovery period, insufficient communication between husband and wife in terms of sexual needs is also one of the important reasons for sexual frigidity. 4. Other factors: such as high work pressure, the application of drugs such as reserpine, paracetamol, ranitidine and other factors such as family relations, may also trigger frigidity. After the occurrence of frigidity, you should seek medical examination as soon as possible to clarify the cause of the disease.
