Fertility preservation for men offers several options to safeguard reproductive potential. These methods are particularly beneficial for those taking treatments that may affect fertility or for men who wish to delay fatherhood. A fertility specialist can guide men through the available methods, helping them make informed decisions about their reproductive future.
Sperm Cryopreservation: Sperm freezing, also known as sperm cryopreservation, is the most common and successful method of preserving a man’s fertility. This process involves collecting a semen sample, usually through masturbation, and freezing it for future use. The sample is mixed with a fluid called a cryoprotectant that protects the sperm from damage during the freezing process. The sperm is then divided into several containers called straws and cooled slowly before being plunged into liquid nitrogen for storage.
Sperm can be stored for several decades, with reports of successful pregnancies using sperm frozen for up to 55 years.. When a person needs them, the frozen sperm can be thawed & used in various fertility treatments, including in vitro fertilization (IVF), intrauterine insemination, and intracytoplasmic sperm injection. The success rates of these treatments using frozen sperm are comparable to those using fresh sperm.
Testicular Tissue Freezing: For men who cannot produce sperm through ejaculation or have very low sperm counts, testicular tissue freezing is an alternative option. In this method, the doctor surgically removes a small portion of testicular tissue, which is then cryopreserved and stored. This technique is beneficial for prepubertal boys facing cancer treatments, as they cannot produce mature sperm.
Both sperm freezing and testicular tissue freezing provide hope for men facing fertility challenges, allowing them to take proactive steps towards their future family planning goals.Â
