Sperm Preservation, What do you need to know?
Sperm preservation as the name suggests, is a procedure to preserve and store the sperms after careful screening and analysis for later use. The procedure of sperm preservation has a number of applications and indications; such as:
- Artificial fertilization
- Treatment of fertility disorders
- Sperm donation (according to unpublished statistics, approximately 30,000 birth each year in United States are attributed to artificial inseminsation)
Regardless of the screening results and protocols of freezing, some sperms fail to endure the process and gets wasted. It is noteworthy that for indications like sperm donation, it is recommended to store the sperms for a period of at least six months to exclude the risk of infections.

With stored sperms what are the chances of my baby to born?
The chances of baby to be born depends upon the feasibility of sperms being stored and the age of the women. The sperms stored do not always survive and they might also undergo reduction with deterioration in the quality of sperms. Success rates with women’s ages are as follow:
- 35 years or less: 19% success rate.
- 35-39 years : 15% success rate.
- 40-42 years : 7% success rate.
What are the risks of freezing and storing sperms?
So far there are no statistics or reported cases of adding risk of genetic/ physiological diseases in babies born as a result of sperm preservation techniques.
What are the options for men or boys undergoing the cancer treatment?
Storage of sperms can be commenced in males at an age of 13 years and onwards. A new technique involves the storage of testicular tissue for patients undergoing a cancer therapy. This tissue storage and freezing can be done even before the puberty, and can be helpful in restoring the fertility after the cancer therapy. Other classic benefit is, promotion of sperm development in a person who is unable to produce sperms. Every clinic licensed by HFEA for sperm storage can store testicular tissues.
