Begin with a male patient with azoospermia, a condition in which semen lacks male gametes or spermatozoa.
The genital area is disinfected and covered with a drape to expose only the scrotum, the organ that houses the testicles, which produce spermatozoa.
Illuminate the region and identify the epididymis, a structure responsible for the maturation and storage of spermatozoa.
Insert a syringe containing a specialized culture solution for gametes into the epididymal tissue.
Apply negative pressure while puncturing the tissue to extract epididymal fluid containing spermatozoa.
Transfer the collected fluid to a dish containing the culture solution to preserve spermatozoa viability.
Using a microscope, count the mature, healthy spermatozoa that exhibit motility.
Transfer the solution to a tube, then centrifuge to separate the spermatozoa and remove the supernatant.
Resuspend the cells in a fresh culture solution.
The isolated spermatozoa are now ready for use in infertility treatment procedures.
To begin, gather a surgical instruments package, two syringes, disinfectant solution, sterile rubber gloves, and adhesive dressing. Examine the surgical instruments package that underwent high pressure s
