What is Cryopreservation and What is a Sperm Cryobank?

Cryopreservation is the process of freezing tissue. In the case of sperm cryopreservation, a man's semen is frozen for future use. A sperm cryobank is a facility that collects, stores and freezes the sperm
Should I Be Considering Sperm Banking?

Sperm banking is used in a variety of different situations. Most commonly, men bank sperm because they are about to undergo treatments or take medications which may affect their sperm production.


For example, you may want to consider cryobanking if:
  • You will be undergoing a treatment for cancer which may impair your sperm production or quality (e.g. chemotherapy, radiation).
  • You will be taking any ongoing medications which may impair your sperm production or quality (e.g. sulfasalazine, methotrexate).
  • You will be undergoing any procedure which could affect your testes, prostate, or your ability to ejaculate (e.g. prostate resection, colon surgery or retroperitoneal lymph node dissection).
  • You have a medical condition which is beginning to affect your ability to ejaculate (e.g. multiple sclerosis, diabetes).
  • You are undergoing a vasectomy.
  • You are entering a line of work where you may be introduced to reproductive toxins.
  • As part of your infertility treatment, you will be undergoing a procedure where sperm may be easily harvested (e.g. vas reconstruction, testicular biopsy). These sperm can then be stored and used later in conjunction with advanced reproductive techniques if alternative infertility treatments do not prove successful.

This list is by no means exhaustive and we encourage you to discuss the issue with your doctor.

Sperm Washing for IUI
Sperm washing is the process which prepares a semen sample for an intrauterine insemination (IUI). For an IUI to be performed, the semen sample must be washed free of debris, white blood cells, and prostaglandins, which can cause the uterus to contract. The processing also removes dead sperm and concentrates the sperm into a small volume which can easily be handled by the uterus. There are three main methods of sperm washing; the swim-up, discontinuous (density) gradient method, and simple centrifuge) wash. The type of wash used depends on the individual characteristics of each semen specimen.
