Sperm freezing is used in artificial insemination, in vitro fertilization, surrogacy and other assisted reproductive procedures. Sperm freezing allows for a process of freezing and storing semen samples so you and your partner may use them to become pregnant in the future.
Storing sperm prior to an IVF, egg donor or surrogacy cycle ensures the availability of sperm should the male partner have difficulty producing a sample on the day of egg retrieval or should the male not be available to produce a fresh sample due to other medical reasons.
Some men discover they have diseases or must undergo treatment or surgery that will cause permanent sterilization or genetic damage. As cancer detection and treatment techniques improve, more cancer conditions are being detected at younger ages in men, with better and longer survival rates. Therefore, more men in their fertile years are now considering this option.
Good candidates include:
When the first specimen is received by the clinic in India, each sample is assessed and evaluated microscopically. Samples are combined with protectant solution to shield during freezing and thawing. The samples are placed in vials that are coded and carefully frozen in nitrogen vapor.
Once frozen, the vials are immersed in liquid nitrogen and stored in cryogenic tanks at a temperature of -196°C (-321°F). The liquid nitrogen is independent of any source of power. Cryogenic tanks are tested daily and refilled as needed.
When it is time for the sperm samples to be thawed, the cryopreserved sperm are checked of good quality. Once the sperm is thawed, it is placed into the female partner’s uterus in a process called intrauterine insemination (IUI), in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI).
Azoospermia is defined as the absence of mature spermatozoa in a clinical semen analysis (male infertility testing). Different surgical methods such as PESA, TESA, TESE and micro-TESE have been developed to retrieve spermatozoa from either the epididymis or the testes.
