Sperm freezing

Sperm freezing, or sperm cryopreservation, is a highly effective method for preserving male fertility. Dr. Abdul Basith holds an MD in Obstetrics and Gynecology, MRCOG (UK) and PD-FRM, with more than 13 years of experience in women’s health and fertility care. Sperm cryopreservation options are evaluated based on individual medical history, diagnosis, and reproductive goals. It is also suitable for men who wish to delay fatherhood due to personal or professional reasons.

The sperm freezing process begins with the collection of a semen sample, either through natural ejaculation or surgical sperm retrieval in cases of azoospermia (absence of sperm in ejaculate). The semen is then analysed to assess sperm count, motility, and morphology. Once the sample is deemed suitable for freezing, it is mixed with a cryoprotectant to prevent damage during freezing and then stored at ultra-low temperatures using vitrification, a method that ensures higher survival rates of the sperm once thawed.

Sperm freezing provides men with long-term fertility preservation, allowing them to father children later in life when they are ready. Frozen sperm can be stored for several years without losing its viability, making it a flexible option for men facing temporary or permanent fertility risks.

When the time comes to use the frozen sperm, it is thawed and used in assisted reproductive techniques such as intrauterine insemination (IUI) or in vitro fertilisation (IVF), depending on the fertility needs of the couple.
