Lack of interest in coitus after giving birth is a relatively common occurrence. On the one hand, it may be related to the fact that after giving birth to a child, too much attention is paid to the care of the child and no interest in engaging in sex, and it is also closely related to the fluctuation of hormone levels. In this case, the communication between husband and wife can be enhanced to improve sexual pleasure. In addition, if the patient, in addition to sexual dysfunction, has low mood, slow thinking, reduced will activity, self-guilt and self-blame, feeling that there is no point in living, no interest in fun, and self-injurious and suicidal thoughts and behaviors, it is diagnosed as depression. When the diagnosis is depression, patients often exhibit sexual dysfunction, which manifests itself as a decrease or complete loss of sexual desire. Some patients are barely able to maintain sexual activity, but experience no pleasure or interest in it. For female patients, menstrual disorders and amenorrhea may occur, so this is more common in the clinic. For this situation, clinical antidepressant treatment is mainly used to improve the symptoms of depression, and by curing the depression, the change of sexual function can be cured naturally. Clinical application of antidepressants mainly pentazocine reuptake inhibitors can get good results.
