The success of artificial insemination is usually determined by the number of times it is performed, and cannot be generalized. Artificial insemination is a popular and simple assisted reproduction technique that uses artificial means to deliver sperm into the woman’s body. Its success usually depends on factors such as male sperm quality, female endometrial thickness and morphology. If the couple is young, the male sperm quality is good, and the female ovulation and intrauterine environment are good, the success rate is high and generally 3-6 times may be successful. If the couple is older, the male sperm quality is poor, and the female ovulation and intrauterine environment are not good, the success rate is lower, and it is possible that IUI is still unsuccessful after 6 times. After IUI, avoid strenuous exercise and overexertion to avoid affecting the implantation, avoid cold and spicy stimulating food, have a balanced diet and avoid excessive mood swings.
