Artificial insemination can be done when the follicle is above 1.7-1.8cm, when it has developed into a mature follicle. Artificial insemination (AI) is an assisted reproduction technique that involves injecting sperm into the female reproductive tract through non-coital means, and is most commonly used clinically as intrauterine insemination. IUI requires a mature follicle and can be performed during a natural cycle or an ovulation induction cycle. When the follicle reaches 1.7-1.8cm or more, it is generally considered mature, and an ovulation injection can be considered to induce ovulation. The next day, artificial insemination can be performed, in which processed semen is injected into the woman’s uterine cavity, completing the process of artificial insemination. Artificial insemination is a means of assisted reproduction and, unlike IVF, requires that at least one of the woman’s fallopian tubes be open in order for artificial insemination to take place. Artificial insemination is relatively simple and natural, so if a normal pregnancy is achieved through this technique, there is no significant difference in the overall process compared to a woman who conceives a child naturally, and all that is required is a routine maternity check-up in the obstetrics department.
