Single sperm freezing is an advanced method of fertility preservation that is employed when the amount of sperm is very low or when it is obtained surgically. Such an approach is very useful in men with severe male infertility or those who are undergoing treatments which can have an impact on fertility. Every sperm is selectively isolated and frozen using specialised laboratory methods to ensure it remains viable in the future in case of IVF or ICSI procedures. The procedure makes sure that only one healthy sperm is kept, and then it can be utilised in fertilisation at a later stage. It is effective in patients with azoospermia that is not obstructive or low sperm motility. By consulting Dr Ram, it is possible to get a proper assessment and a successful cryopreservation depending on the particular reproductive objectives and medical histories.
