What are the causes of secondary infertility

Reason 1: serious chronic diseases and endocrine disorders. Endocrine changes, hyperprolactinemia, luteal insufficiency, anovulation (LUFS) and so on can cause some aspects of egg production obstacles, leading to infertility.

The second reason: uterine cavity is not only the only way for sperm to reach the oviduct and meet the egg, but also the place where the fertilized egg is implanted. Local pathological changes of uterus may hinder the ascending of sperm and the implantation of pregnant eggs, resulting in infertility. Infertility caused by simple uterine factors is rare, accounting for only 2%. Such as uterine malformation, uterine dysplasia, uterine submucous myoma, tuberculous endometritis, intrauterine adhesions caused by repeated curettage, etc.

Reason 3: in the process of pregnancy, the cervix is the main barrier for sperm to reach the site of pregnancy, and it is the only way for sperm to reach the fallopian tube. Cervical mucus not only creates a good environment for the survival and activity of sperm, but also plays a role in screening ascending sperm.
