What tests are needed before artificial insemination? When is artificial insemination?

Artificial insemination is the process of injecting male sperm into the female genitals to promote natural conception of sperm and egg. So what tests need to be done before artificial insemination? When is the best time for artificial insemination? Let's learn about it together~

Preparations for artificial insemination

1. Before collecting semen, you should abstain from sex for 3-5 days, refrain from smoking, drinking, and taking drugs that may harm sperm.

2. Usually masturbation is used to collect semen. For patients with anejaculation, if masturbation is not effective, an electric massager can be used to collect semen. All semen is collected in a special non-toxic, sterile and dry semen collection container and stored at a certain temperature (not less than 20°C and not more than 40°C). It should be used within about 1 hour, and a routine semen examination should be performed before use.

3. For patients with retrograde ejaculation, empty the bladder first, then flush the bladder with sterile saline, and finally inject a small amount of sperm culture fluid or other liquid that is harmless to sperm into the bladder. Urinate or catheterize immediately after masturbation or sexual intercourse ejaculation, and centrifuge and wash the semen before artificial insemination.

4. For patients with low semen volume and sperm count, semen can be collected several times and concentrated before artificial insemination.

5. If you do not use masturbation to collect semen due to religious beliefs or other reasons, you can also use special condoms to collect semen during sexual intercourse.

Preparations for the woman before artificial insemination

1. Reproductive system examination: Check for any deformities, pelvic masses or inflammation, whether the uterus is in the normal position, and whether the fallopian tubes are unobstructed; check the cleanliness of vaginal secretions and cervical mucus and whether there are any reproductive tract infections (such as Trichomonas and fungi). If necessary, check for sexually transmitted diseases (such as AIDS, gonococci, Treponema pallidum and mycoplasma, etc.). Relevant diseases should be treated appropriately first.

2. Psychological preparation: Psychological preparation is an issue that is often overlooked during artificial insemination treatment. The psychological state of both men and women has a certain impact on the success of artificial insemination. The psychological state of women has a certain impact on the stability of her gonad axis, that is, it affects her endocrine stability. During artificial insemination treatment, it is necessary to understand the psychological state of both men and women, especially women, and appropriately cooperate in psychological counseling and related treatment during the treatment process.

3. Ovulation monitoring: The most important thing in the woman's preparation is to monitor ovulation during the menstrual cycle. This is the most critical and important item in the woman's preparation. Artificial insemination should be done during the woman's ovulation period, which is 48 hours before ovulation to 12 hours after ovulation. There are many methods for ovulation monitoring, including basal body temperature, cervical mucus, sex hormone measurement, vaginal B-ultrasound monitoring, etc. Among them, monitoring ovulation through vaginal ultrasound is the most objective and reliable method, and this method should be used if conditions permit. Basal body temperature is a method that patients can perform at home under the guidance of a doctor. This method is still an economical and applicable method. It can be used alone or in combination with other methods such as cervical mucus observation and sex hormone measurement.

During the artificial insemination treatment cycle, the woman should go to the hospital for the first B-ultrasound to monitor the development of follicles around the 11th day of menstruation (starting from the time of bleeding). According to the development of follicles, the doctor will inform the time of the next B-ultrasound and the medication.

Operation time: When the diameter of the follicle reaches 18-20mm or more, the doctor will decide the operation time according to the cervical mucus and urine LH. Generally, the operation is performed when the cervical mucus score is greater than 10 points, the urine LH is positive or after the use of human chorionic gonadotropin hCG. Insemination may be performed once or twice in the same cycle, that is, once before ovulation and once after ovulation.

If B-ultrasound shows that the follicles and endometrium are poorly developed, please temporarily abandon the cycle and wait for the next cycle or undergo drug treatment before undergoing surgery.

Collect your first urine in the morning 14-16 days after surgery, do a pregnancy test, and tell your doctor the result.

If you are pregnant, you should stay in touch with the hospital you are being treated at throughout your pregnancy. This will help you get through your pregnancy safely.

If pregnancy does not occur after 4-6 cycles of artificial insemination, other treatment options are needed, such as ovulation-inducing drugs or in vitro fertilization-embryo transfer (IVF).

Families who want artificial insemination must cooperate with the doctor.

Many couples want to undergo artificial insemination, but are worried that the process is complicated and time-consuming. So let's take a look at what the process of artificial insemination is like.

First of all, infertile women who are undergoing artificial insemination need to undergo a detailed gynecological examination to check whether their internal and external genitalia are normal, whether the endometrial biopsy glands secrete well, whether the bilateral fallopian tubes are unobstructed, etc. If all these are normal, they are qualified for artificial insemination. Then it is necessary to estimate the ovulation day to choose the best time for insemination. Commonly used methods for estimating the ovulation day include measuring basal body temperature, cervical mucus (usually appears 4-5 days before ovulation), or continuously measuring the peak of urinary luteinizing hormone close to the ovulation day, or continuous vaginal ultrasound examination, etc.

Before the woman's estimated ovulation period, the sperm donor or husband masturbates to extract semen, which needs to be tested. If the results show that the semen density and activity are normal, the semen is injected into the vagina, around the cervix and into the cervical canal with a syringe or catheter after it liquefies. The woman rests in bed for 2-3 hours to prevent the semen from being discharged.

Each woman can undergo artificial insemination three times in a menstrual cycle, starting three days before ovulation. If calculated by hours, it can be done once 72 hours, 24 hours before ovulation, and 24 hours after ovulation. If conception fails in a menstrual cycle, several cycles can be repeated. If necessary, drugs can be used to induce ovulation and adjust the ovulation period to increase the pregnancy rate. The success or failure of artificial insemination is generally determined by 12 cycles.

According to the different sites of fertilization, it is divided into 6 types: 1. Intravaginal artificial insemination; 2. Intracervical artificial insemination; 3. Intrauterine artificial insemination; 4. Intraperitoneal artificial insemination; 5. Intrafollicular artificial insemination; 6. Vaginal intrafallopian artificial insemination.
