Sperm banks help overcome male infertility, prevent hereditary diseases, and give single women the chance to become mothers. For patient safety, biomaterial must be frozen in liquid nitrogen for at least six months to rule out hidden infections. For married couples, this decision is often psychologically difficult due to the lack of a genetic connection between the child and the father, so it is important for spouses to consciously accept this fact before starting the procedures. All donors undergo a strict selection process, which includes in-depth medical and genetic testing to ensure the health of the future child.
