Pregnancy is the fruit of love with the joint efforts of both husband and wife, but some couples fail to bear fruit in any way, so it is important to find out where the cause lies. Infertility is actually a general term for infertility and infertility, simply put, infertility is caused by female problems, while infertility is caused by male problems, so the causes of infertility should be categorized. First of all, we need to know the conditions that must be fulfilled for conception. A normal egg from the ovary meets a healthy sperm in the fallopian tube to form a fertilized egg, and the endometrial lining of the uterus is used for the development of a fertilized egg. Infertility in women is mainly related to abnormal ovulation and reproductive system problems. If a pregnant woman has no ovulation during menstruation or has genital abnormalities and lesions such as blocked fallopian tubes, uterine malformations, gynecological inflammation, gynecological tumors, etc., these are the main causes of infertility in women. In men, the causes of infertility are mainly related to urinary system problems and genital problems including some inflammatory diseases such as prostatitis, orchitis, urethral infections, etc., which directly affect the natural discharge of semen. In the case of testicular atrophy, testicular trauma, testicular torsion, cryptorchidism, etc., the production of sperm is directly affected thus leading to infertility.
