What are the methods of artificial insemination? What are the conditions for artificial insemination?

Artificial insemination is a medical method for treating infertility. So who is qualified for artificial insemination? What are the requirements for artificial insemination? What are the methods of artificial insemination? Let's learn more about it~

What are the methods of artificial insemination?

There are many methods of artificial insemination. You should pay attention to the method you choose. In daily life, if you want to do this operation, you should pay attention to some matters. Both men and women should remain normal. Moreover, you should pay attention to the occurrence of some diseases and pay attention to understanding the restrictions. So, what are the methods of artificial insemination?

1. Intravaginal artificial insemination

Use a syringe connected to a plastic tube to inject semen into the vagina and lie flat for 20 minutes.

2. Intracervical artificial insemination

Use a dilator to expose the cervix, inject 0.2-0.3 ml of semen into the cervical canal, and inject the remaining semen into the anterior and posterior fornixes, and lie flat for 20 minutes.

3. Intrauterine insemination

① Injecting a small amount of original semen into the uterine cavity: Inject 0.3 ml of semen into the uterine cavity. Since the prostaglandins in semen can cause spasmodic contractions of the uterus and cause abdominal pain, it can also cause infection, and the amount of semen injected is small, which reduces the chance of conception, so this method is generally not used.

② Washing semen for intrauterine artificial insemination: Washing can remove factors that inhibit fertilization, prostaglandins and antisperm antibodies contained in the seminal plasma, and obtain a preferred concentrated and highly active sperm suspension, which can improve the pregnancy rate. Washing semen intrauterine injection method: The speculum exposes the cervix, a dry cotton ball wipes off the vaginal and cervical secretions, and a thin plastic tube is inserted into the uterine cavity through the cervical canal. After slowly injecting, lie flat for 20 to 30 minutes. Washing semen for intrauterine artificial insemination generally requires no less than 3 treatment cycles.

4. Insemination using a cervical cap

First, a cervical cap that is the right size for the woman's cervix is ​​prepared. The husband's semen is placed inside the cervical cap, which is then covered on the woman's cervix. The patient is then allowed to go home and can take it out herself after 24 hours.

5. Intraperitoneal artificial insemination

In addition to infertility testing before treatment, laparoscopy is also required to confirm that there are no abnormalities in the pelvic organs and fallopian tubes. Induce ovulation and insemination within 24 to 38 hours after intramuscular injection of HCG when the diameter of the follicle reaches 18 to 20MM. Under sterile conditions, puncture the uterine rectal fossa through the posterior vaginal fornix, and aspirate the peritoneal fluid to confirm the correct position of the needle. Puncture can also be performed under the guidance of abdominal B-ultrasound. An average of 0.1 to 23×10.6 washed live sperm are injected. If the follicle has not ruptured after 24 to 48 hours, another puncture and insemination will be performed. After that, the pregnancy status will be monitored by blood HCG and B-ultrasound, and antibiotics will be used after surgery.

6. Direct intrafollicular insemination

Superovulation. When the follicle diameter is greater than 18 mm, two follicles are punctured through the vagina under the guidance of vaginal B-ultrasound, and about 20,000 washed normal sperm are injected into each. Pregnancy is monitored after surgery.

Everyone needs to understand it as soon as possible, and pay attention to comprehensively conditioning the body to avoid causing more troubles. At the same time, in daily life, pay attention to care methods, comprehensively conditioning the body to avoid causing more harm and bringing adverse effects, and also pay attention to comprehensively conditioning the body according to the doctor's advice.

Sources of semen for artificial insemination

(1) Artificial insemination by husband (AIH) is artificial insemination using the husband's semen. The semen can be used directly or treated to improve the quality of the semen before use;

(2) Artificial insemination with donor sperm (AID) is artificial insemination with sperm from other men. The sperm donor must be free of genetic or infectious diseases, have good intelligence, good physical condition, and good semen quality;

(3) Mixed sperm artificial insemination is to mix the sperm of the sperm donor and the husband's sperm for artificial insemination. In fact, this method has no advantages. On the contrary, due to the harmful factors in the sperm of the infertile husband, the semen quality of the healthy sperm donor will be reduced. Infertile couples who request to use this method have a fluke mentality (especially those with oligospermia), thinking that their own sperm may be successful in artificial insemination. This method is not recommended.

How to use semen for artificial insemination

(1) Artificial insemination with frozen sperm: The semen is stored at ultra-low temperatures and can be taken out and rewarmed for use at any time when needed. The advantage of this method is that the semen can be divided into several portions and used several times. It can also collect a small amount of sperm from severe oligoasthenozoospermia and use it all at once. The disadvantage is that the sperm that has been frozen will always be damaged to some extent, so the success rate of insemination is not as high as that of fresh sperm.

(2) Artificial insemination with fresh sperm: The semen is used within one hour of being obtained. The success rate of insemination is slightly higher than that of frozen semen. However, due to the influence of time, location, environment and other factors, the source and confidentiality are extremely inconvenient.

What are the necessary conditions for artificial insemination?

Artificial insemination is just a simple assisted reproductive technology that can effectively help women who cannot conceive naturally to become pregnant. However, this technology is not available to everyone. It can only be performed if the conditions for artificial insemination are met. So, what are the necessary conditions for artificial insemination?

Experts say that women who undergo artificial insemination must keep one side of their fallopian tubes unobstructed. After the ovary releases an egg, it is first taken in by the fallopian tube, where it meets the sperm and becomes a fertilized egg, which is then transported to the uterine cavity by the fallopian tube in a timely manner. Once a blockage occurs, artificial insemination cannot be used to assist pregnancy. Moreover, artificial insemination has certain indications, and only patients who meet the indications can undergo this technology.

Before artificial insemination, infertile couples must undergo relevant examinations, which include six endocrine examinations, seven infertility antibody examinations and monitoring of follicle development on the third day after the woman's menstruation. The man needs to have a routine semen examination. The couple should undergo routine examinations, and the woman should have vaginal secretions, cervical cytology, seven infertility antibodies and hysterosalpingography 3-7 days after the menstruation ends.

Finally, there are three necessary certificates for artificial insemination. Infertile couples must prepare both parties’ ID cards, marriage certificates and birth permits. None of the three certificates can be missing.

In addition, patients must choose a regular artificial insemination hospital to ensure the success rate of artificial insemination.
