Ways of obtaining sperm from test tube babies
IVF technology is an assisted reproductive technology that helps couples who cannot conceive naturally realize their dreams of childcare. Among them, obtaining high-quality sperm is one of the important steps for successful IVF. The following will introduce in detail the ways to obtain IVF sperm from the aspects of donation, extraction, processing and storage.
1. Donate and collect sperm
Sperm can be donated and collected by specific medical institutions. Some qualified hospitals have sperm donation centers that accept voluntary sperm donations from healthy men. Donors are usually required to be 20-45 years old, healthy and free from genetic diseases. Donors need to undergo detailed physical examination and genetic counseling to ensure the quality and safety of sperm. Once the donor meets the conditions, the hospital will conduct sperm collection, usually through semen samples.
2. Sperm extraction and treatment
The donated sperm needs to be extracted and processed to obtain high-quality sperm for use in the IVF process. Sperm extraction can be carried out by autologous ejaculation or artificial assisted ejaculation. Autoejaculation means that the donor discharges semen samples through masturbation, and then professional medical personnel extract them. Artificial assisted ejaculation refers to the assisted ejaculation by medical devices or drugs. The extracted sperm needs to be centrifuged, washed and measured to obtain a sperm sample with high purity and appropriate quantity.
3. Sperm storage and preservation
After obtaining high-quality sperm, the sperm needs to be frozen for future use. There are two main ways to store sperm, namely, liquid nitrogen freezing method and dry ice freezing method. The liquid nitrogen freezing method puts the sperm sample in the specific liquid nitrogen, and reduces the temperature to a very low level to prevent the metabolism and variation of the sperm. The dry ice freezing method uses dry ice to freeze the sperm samples, with a lower temperature but a more stable. No matter which freezing method is used, the hospital will ensure that the sperm is kept under the best conditions to maintain its quality.
4. Use and delivery of sperm
Once couples choose to use IVF technology, the hospital will select high-quality sperm samples from the frozen sperm bank to thaw and solve problems according to the specific situation, and then inject sperm into the female's oocytes for embryo culture. After a suitable embryo is cultivated, it is transferred back to the woman's uterus in the hope of achieving pregnancy and healthy reproduction.
summary
The ways to obtain IVF sperm include donation, extraction, processing and storage. Donors must meet specific medical conditions and undergo detailed examination and genetic counseling. After the sperm is extracted by autologous ejaculation or artificial assisted ejaculation, the sperm is processed by centrifugation, washing and measurement. The treated sperm samples can be preserved by liquid nitrogen freezing method or dry ice freezing method. Once sperm is needed, the hospital will select high-quality samples for thawing and transplantation according to needs. The way to obtain IVF sperm is realistic. Reliable and feasible medical technology provides new reproductive options for couples who cannot conceive naturally.
