What is artificial insemination? The so-called artificial insemination is simply to transport sperm to the female reproductive tract in a non-sexual way, so that sperm and eggs can naturally combine to achieve the purpose of getting a woman pregnant.
According to the source of sperm, artificial insemination can be divided into husband insemination of husband sperm and donor insemination of third-party sperm.
According to the different parts of insemination, such as vagina, cervical canal, uterine cavity, fallopian tube, abdominal cavity, etc., they are called artificial insemination in vagina, artificial insemination in cervical canal and artificial insemination in fallopian tube, among which intrauterine insemination is the most common.
Professor Zhang Jianping, director of obstetrics at Sun Yat-sen Memorial Hospital of Sun Yat-sen University, said in a previous interview that intrauterine insemination has become a common method to treat male infertility. "Intrauterine artificial insemination is suitable for male oligozoospermia, azoospermia, positive antisperm antibody, abnormal ejaculation, non-liquefaction of semen and unexplained infertility. Compared with other assisted reproductive technologies, intrauterine insemination technology has less damage and lower cost, and is often given priority. "
Generally speaking, the pregnancy rate of artificial insemination is slightly higher than that of natural sexual intercourse between normal couples, and the success rate is about 15-20%.
What is IVF? The biggest difference between IVF and artificial insemination is that IVF adopts in vitro fertilization technology, which is in vitro fertilization-embryo transfer as a whole.
The operation method of IVF is more complicated than artificial insemination. Generally speaking, it is necessary to obtain eggs through superovulation of women, and puncture them into pelvic ovaries under the guidance of vaginal B-ultrasound to suck out women's eggs. At the same time, the husband takes sperm by himself or through surgery, takes out the sperm eggs and processes them in the laboratory, then fertilizes them, divides them into embryos and implants them into the uterus cavity of the woman, and further develops into a fetus until delivery.
In the field of reproductive therapy, IVF is generally used as the next treatment for patients who have failed in artificial insemination. For infertile patients who are still not pregnant after 3-6 cycles of artificial insemination, doctors generally recommend IVF treatment.
The success rate of IVF is related to women's age and reproductive disorders. Ideally, the success rate of IVF for healthy women of childbearing age is about 50%.
