What are the causes of infertility and how is it treated?

Patient's question:

Infertility for two years

Doctor's answer:

Fertilization is a complex physiological process that requires the following conditions:
1. The ovary must release a normal egg
2. Sperm must be normal and contain healthy sperm
3. The egg and sperm must meet and combine in the fallopian tube to form a zygote
4. The zygote must be successfully transported into the uterine cavity
5. The endometrium must be fully prepared to support the implantation of the zygote.
If any of these steps are abnormal, fertilization can be hindered. The reasons for infertility may be related to the female, the male, or both. It is recommended that you visit a specialized hospital for a detailed examination, receive a clear diagnosis, and undergo targeted treatment.
