MODEL RELEASED. Sperm bank. A technician prepares to remove a sample of frozen sperm from a storage unit in a sperm bank. This container is filled with liquid nitrogen,which keeps its contents at -180 degrees C. After a sample is removed and thawed,the most healthy sperms are selected by a computer imaging system and then used for in vitro fertilisation to treat infertile couples. Storage of frozen sperm can preserve a man's ability to have children if his fertility is threatened by cancer of the testis. Use of sperm from an anony- mous donor can also help couples where only the male partner is infertile | |
