Fertility preservation (Sperm)

Freezing sperm is a very simple procedure for the patient. The sperm is collected by masturbation; it is then analyzed and processed for freezing by the laboratory. If the patient has an ejaculation disorder or a diagnosis of infertility, the sperm can be retrieved surgically. The first option is to retrieve the sperm directly from the epididymis (percutaneous epididymal sperm aspiration, or PESA). The second is to collect it directly from the testicle (testicular sperm extraction, or TESE).

MEDICAL REASON

Many diseases require the use of treatments that can be harmful to the reproductive system. Cancer patients are especially vulnerable, as chemotherapy, radiation therapy, and pelvic surgery can all, to varying degrees, lead to alterations in gametogenesis (the biological formation of eggs and sperm), ovarian and testicular function, or even sexuality.
 
The fertility preservation program at clinique ovo has grown significantly. We are very proud of the fact that increasing numbers of oncologists are referring their patients to us to preserve their eggs and sperm before undergoing chemotherapy, and thus their ability to have a child after they recover from their illness.

 

When to proceed with fertility preservation?
It is recommended to start fertility preservation procedures before beginning chemotherapy or radiation therapy, and/or undergoing surgery, in order to preserve sperm or eggs of the best possible quality.

STEPS IN PRESERVING SPERM

How does sperm collection work?
A patient who wants to preserve his fertility must make an appointment with the ovo cryo team, who will explain the procedure and offer him the necessary support.
 

Preliminary consultation
During his appointment at the clinic, the patient will be given information about sperm preservation methods and the use of his sperm. He will be asked to sign a consent form outlining the terms of preservation. We will ask him to undergo blood tests (hepatitis B, hepatitis C, HIV, syphilis) prior to freezing his sperm.

 

Performing the sperm retrieval
The sperm is collected by masturbation in a room provided for this purpose and then sent to the laboratory. Time permitting, the patient should abstain from sexual activity for 2-3 days prior to the retrieval. It is also recommended that the patient deposit several sperm samples in order to build up a sufficient reserve, again, time permitting.
In the event sperm collection is impossible or in certain specific cases (spinal injury, paraplegia, ineffectual masturbation), sperm collection techniques, such as vibrating massage or electrostimulation, can be used.

Analyzing the sample
The sample is analyzed for various parameters: volume of the ejaculate, sperm count, and sperm morphology and motility. A serology test is also required before the sperm can be frozen.
 
If, after analysis, the sample quality is deemed unsatisfactory, a second sample may need to be collected in order to optimize the chances of successful freezing.
 

 
Freezing the sample
The sample is prepared and treated with cryoprotective agents before being packed into straws. It is then gradually frozen to a temperature of -196°C (temperature at which all biological activity ceases). Finally, the sample will be stored in liquid nitrogen in a secure location until use. Once frozen, the sperm can be stored indefinitely without a significant loss of fertility.
 
Annually, patients must reaffirm their desire to continue storing their sperm. At any time, patients can request, in writing, that we stop storing their sperm, at which point the specimens will be destroyed or, with the patient’s consent, used for research purposes.
