Which is better, artificial insemination or test tube

In fact, there is nothing particularly good or bad about artificial insemination and in vitro fertilization. The biggest difference is that one treats male infertility and the other treats female infertility. For natural conception, neither is very good. Artificial insemination is to implant sperm into the female uterus and then conceive, while in vitro fertilization is to combine the egg and sperm in vitro and then transfer them to the female uterus. Both are harmful to the body, and it is not easy to preserve the fetus. This article introduces the difference between the two in detail. Let's take a look.

The biggest difference

1. Artificial insemination is a method of conception in which semen is artificially injected into the female uterus. Mainly used for male infertility.

2. In vitro fertilization is a method of conception in which the woman's egg is taken out and combined with sperm in vitro to form an embryo, which is then transferred into the uterus. It is mainly used for female infertility.

Detailed differences

1. Differences in definitions

Artificial insemination refers to a method in which male semen is artificially injected into the female cervix or uterine cavity to assist conception.

In vitro fertilization is a series of techniques that use reproductive assisted technology to manipulate sperm, eggs and embryos in vitro and then send them into the human body to help infertile couples have children. It includes artificial insemination, fallopian tube gamete transfer and in vitro fertilization-embryo transfer. The pregnancy process of in vitro fertilization is the same as that of normal pregnancy.

2. Different applicable groups

Artificial insemination is mainly used for infertility caused by male factors, such as severe hypospadias, retrograde ejaculation, erectile dysfunction, azoospermia, oligospermia, asthenospermia, and semen liquefaction disorder. Artificial insemination can also be used for some female-related infertility, such as vaginismus, small cervix, abnormal cervical mucus, poor post-coital test, etc. In addition, there are some special cases, such as infertility due to immunological reasons, where both husband and wife are heterozygous for the same autosomal recessive genetic disease or the male has an autosomal dominant genetic disease, artificial insemination can also be used to achieve pregnancy and avoid the birth of unhealthy offspring.

IVF is suitable for people: IVF is mainly used for infertility caused by women, such as severe fallopian tube disease, endometriosis, immune infertility, anti-sperm antibodies in the male semen or female cervical mucus, such as unruptured follicle syndrome, etc.

In vitro fertilization is also suitable for a small number of male infertility patients caused by oligospermia, asthenospermia, and teratospermia. Those who have genetic diseases and need pre-implantation diagnosis or those who cannot be cured of infertility for a long time can use IVF.

3. Success rate

The success rate of artificial insemination mainly depends on the following four aspects.

First, the predictability of ovulation is important. The more regular your menstrual periods, the higher your chances of getting pregnant.

Secondly, men with good sperm count and motility but unable to have sexual intercourse have a significantly higher chance of successful artificial insemination than men with sperm abnormalities.

Third, a history of endometriosis or pelvic infection or fallopian tube disease reduces the success rate, but those who have been pregnant before have a higher success rate.

Fourth, if the woman is too old (over 35 years old), her chances of pregnancy are significantly reduced.

The success rate of in vitro fertilization depends on many factors. One is whether the treatment of one's own eggs is good, the quality of impregnation is good, the quality of sperm-egg combination is good, and the environment of the uterus after implantation is good. But there are human factors involved here, such as human egg retrieval, human cultivation, and human implantation, so there are many human factors in the whole process. And the current success rate of in vitro fertilization is not very high. Generally, experts advise patients to consider carefully.
