Source of IVF sperm collection
IVF is an assisted reproductive technology. It helps couples who cannot conceive naturally realize their reproductive dreams by fertilizing sperm and eggs in vitro, and then implanting the fertilized eggs into women's uterus. Sperm collection is an important part of IVF process, which determines the quality and success rate of fertilized eggs. At present, IVF sperm collection is mainly conducted from the following four aspects.
1. The wife's husband or partner
The most common source of sperm collection is the woman's husband or partner. In most cases, doctors will first suggest to try natural pregnancy. If it fails, IVF will be considered. When men suffer from problems such as low sperm quality or azoospermia, sperm collection is needed to solve them. Usually, men will go to the reproductive center of the hospital for semen collection, which is a simple but non-invasive operation.
2. Anonymous sperm donors
If the woman's husband or partner has no sperm or poor sperm quality, or they have genetic diseases, etc., they can consider using sperm from anonymous donors for IVF. The hospital or reproductive center will select and record qualified donors. The identity of the donor is usually confidential, which can ensure personal privacy. The woman can choose the right donor according to her own conditions and needs to ensure the quality and health of the fertilized eggs.
3. Autologous sperm freezing
For men who are about to receive treatment, sperm collection can be carried out in advance, and then the collected sperm can be frozen. This method can ensure that sufficient quantity and quality of sperm are available for use in the medical process. In cases where fertility is affected by treatment of specific diseases, surgery, chemotherapy, etc., doctors will advise men to collect and freeze sperm in advance for future use.
4. Donor's family members donate semen
In some special cases, such as the case where a man dies or dies but hopes to have children, his family can consider donating sperm. This method needs to go through the formal process and procedure of the hospital and obtain the explicit consent of the family members. This measure has been widely accepted in many countries, bringing hope to families who have lost their loved ones.
Specific sperm extraction method
Sperm collection is an important link in the process of IVF, to ensure that the quality and quantity of sperm collected are sufficient for IVF. According to the specific situation, the following are several common methods of semen extraction.
1. Manual masturbation
Manual masturbation is the most common way of sperm collection. The male can complete it by hand without any pain, and collect the collected semen in a container. This method is simple, safe and non-invasive, and will hardly cause adverse effects on individual physiology and psychology.
2. Artificial pregnancy aid
For men who cannot masturbate manually, such as in the case of spinal cord injury, artificial pregnancy can be performed. Doctors use specific tools and techniques to stimulate men's sexual response and promote semen excretion. This method requires the professional operation of doctors to ensure effective results.
3. Puncture technology
For men with some pathological conditions, such as ejaculation disorders, sperm collection can be conducted through puncture technology. The doctor will conduct puncture at the appropriate location and use specific instruments to collect semen. This method requires the support of doctors' professional skills and equipment to ensure that sampling will not cause any harm to patients.
