Why store your sperm?

Here are a few reasons why you may want to store your sample:

  • A doctor recommended it for you
  • To insure your healthiest sperm for your future
  • You’re not planning on having kids for years
  • You’re planning on getting a vasectomy
  • You’re in a high risk environment (you’re in the military or exposed to chemicals that impact fertility)
  • You’re undergoing a medical procedure or treatment that will reduce your fertility (chemotherapy, radiation therapy, or gender affirming therapy)
