Sperm (the reproductive cells found in a man’s semen) is typically collected through masturbation. A man can choose to collect his sample at home or in our clinic, but should only use an approved, sterile lubricant that doesn’t harm the sample quality.
Men are also asked to abstain from sexual activity for approximately two days prior to the appointment to allow for the best possible specimen. Once a semen sample is provided it is tested for sperm quantity, shape and movement within each specimen.
If sperm are not present in the sample or if the man is unable to ejaculate, a surgical retrieval to remove sperm directly from the testicle is another option.
Next, the samples are separated into multiple vials to be frozen. Lab technicians will use specialized cryoprotectant (“anti-freeze”) agents to help preserve and protect sperm cells. The frozen sperm is then stored in the lab until needed. When the time comes, the sperm is thawed, washed and tested for mobility prior to use in IUI or IVF.

Many couples with male factor infertility have successfully conceived with IVF using sperm extraction methods.
QWhat is the optimal age to do sperm freezing?
The optimal age for sperm freezing is under 40 years old, in healthy men without family histories of cancer or other hereditary disease.
QWhat is the success rate of this process?
The refinement of microsurgical techniques, combined with advances in cryopreservation technology, has resulted in high pregnancy rates. Many couples with male factor infertility have successfully conceived with IVF using sperm extraction methods.
QHow do you retrieve sperm if the man can’t ejaculate?
If the man can’t ejaculate, we will proceed with a surgical retrieval to remove sperm directly from the testicle.
