Sperm Freezing — Fertility Preservation for Men

CCRM offers sperm freezing for men age 50 and under who are interested in preserving their fertility.

The Male Biological Clock

Unlike women who are born with all of their eggs, men continuously produce new sperm throughout adulthood. But like their female counterparts, men do have biological clocks!

Studies have found that men who are age 45 and older, are at-risk of new genetic mutations and other abnormalities in their sperm, which greatly increases the risk of genetic disorders and childhood health risks.

Know the Risks

Examples of increased health risks to children with older fathers:

  • Autistic spectrum disorders (up to 6 times greater risk)
  • Schizophrenia (3-4 times greater risk)
  • Type 1 diabetes (1.5 times greater risk)
  • Marfan syndrome (incidence of 1 in 5,000 births; 30% new mutations)
  • Alport syndrome (incidence 1 in 5,000 births; 10% new mutations)
  • Achondroplasia (incidence 1 in 15-40,000 births; 80% new mutations)
  • Neurofibromatosis (incidence 1 in 3,000 births; 50% new mutations)
  • Crouzon syndrome (incidence 1 in 25,000 births; about 50% new mutations)

Sperm Freezing

In order to maximize your chance of having a healthy baby, CCRM recommends men who are younger than 50 and plan to have children in the future, to freeze their sperm.

What is the Sperm Freezing Process?

The sperm freezing process is convenient and safe and includes the following steps:

  • Blood test to screen for infection (HIV, hepatitis, etc.)
  • Provide a semen sample (typically through masturbation)
  • Lab analysis of sperm quantity and quality [Learn more about semen analysis]
  • Freezing of viable sperm
  • Storage of the sperm until you’re ready to have a family

CCRM Research on Advanced Paternal Age

CCRM is proud of our groundbreaking study on advanced paternal age and its impact on health risks to children. For the first time, CCRM scientists have been able to identify the mutations in sperm that predispose children to neurodevelopmental disorders, such as autism. Ongoing research at CCRM is investigating how understanding the mechanisms of these advanced paternal age risks will hopefully lead to future healthy offspring.
