Hi all! As for me, it is also worth emphasizing the process of freezing sperm, because without it ART is almost impossible to accomplish. Sperm freezing, also known as sperm cryopreservation, is a process in which sperm cells are preserved at very low temperatures (-196°C) for future use. This technique is used in assisted reproductive technology (ART) as it can help men preserve their fertility, increase chances of conception, provide donor sperm and offer convenience for future family planning.
