Method and process of male semen extraction for IVF
In vitro fertilization (IVF) is a kind of assisted reproductive technology, in which male sperm extraction is one of the key steps. Patients with male infertility or poor semen quality can obtain semen by the following methods.
1. Masturbation and semen collection
Masturbation semen collection is one of the most common methods of semen collection. Male patients inject semen into sterile containers through masturbation in specific rooms. Then, the doctor further treats the semen and extracts sperm for use in test tube babies.
In some cases, men may not be able to complete the masturbation excitation due to psychological or physiological reasons, and then other methods of semen extraction can be used. For example, use electronic stimulator for artificial stimulation, or use pelvic massage for stimulation.
2. Sperm collection by testicular puncture
Testicular puncture is suitable for male patients who cannot collect enough sperm through masturbation or other conventional methods. This method can be completed by local anesthesia or general anesthesia.
Doctors will use a special needle to puncture the testicle, and then collect semen by negative pressure or injection of liquid. The semen collected will be centrifuged to separate sperm, which will be used in the assisted reproductive process of IVF.
3. Sperm taking from spermatic vein
Spermatic vein semen collection is suitable for men with varicocele. In this method, the spermatic vein is ligated by surgery, resulting in the sperm accumulating in the seminal vesicle before blocking, which is convenient for sperm extraction.
The doctor will open the scrotum, find the spermatic vein and ligate it. By blocking the spermatic vein, sperm will accumulate at the blocked position. Doctors can directly collect semen from the seminal vesicle for further assisted reproduction of IVF.
4. Removal of testis or epididymis
Sperm extraction after orchiectomy or epididymectomy is suitable for men with epididymis or testicular diseases. Doctors remove the epididymis or testis through surgery, and send the tissue to the laboratory for processing and sperm extraction after surgery.
After these resected tissue samples are tested, high-quality sperm will be extracted and used for IVF assisted reproduction.
