Step-by-step guide: How does freezing sperm work?

Many technological advancements have allowed couples and individuals to preserve their fertility options, one of which is the process of freezing sperm. This incredible feat of science enables individuals to store their semen for future use, giving them the opportunity to conceive a child at a later date. But how exactly does this process work? Join us as we delve into the fascinating world of freezing sperm and provide you with a step-by-step guide on understanding its inner workings.

Step 1: Collection

The first step in freezing sperm involves collecting a sample. This may sound like an awkward or uncomfortable task, but rest assured, professionals ensure a comfortable and private environment for this process. The donor typically masturbates into a sterile cup provided by the fertility clinic or specialized facility. It’s important to note that abstinence from sexual activity for two to five days beforehand is generally recommended as it helps optimize sperm quality and count.

Step 2: Evaluation

Once the sample has been collected, it undergoes evaluation by experienced embryologists. They examine various factors like motility (movement), concentration (number of sperm per milliliter), morphology (shape), and vitality (live vs. dead). Assessing these characteristics allows experts to identify any potential issues or abnormalities that may affect the success rate when using the frozen sperm for conception.

Step 3: Preparation

In order to protect the fragile structure of sperm cells during the freeze-thaw process, they need to be properly prepared before cryopreservation. To achieve this, scientists mix the collected sample with special protective solutions often containing cryoprotectants, such as glycerol or dimethyl sulfoxide (DMSO). These cryoprotectants act as antifreeze agents, safeguarding against ice crystal formation inside the cells during freezing.

Step 4: Freezing

The next step involves subjecting the prepared sample to controlled cooling processes. Slow freezing and rapid freezing (vitrification) are two commonly employed methods. Slow freezing involves gradually decreasing the temperature of the sample to -196 degrees Celsius (the temperature of liquid nitrogen) using programmable freezers. On the other hand, vitrification rapidly freezes the sperm in an ultra-fast manner by plunging it directly into a liquid nitrogen bath.

Step 5: Storage

Following successful freezing, the preserved sperm samples are placed in specially designed containers called cryovials or cryostraws. These containers protect the sperm from contamination and prevent any damage caused by temperature variations during storage. Cryopreserved sperm can be stored for extended periods, ranging from months to even decades, thanks to the outstanding stability offered by liquid nitrogen.

Step 6: Thawing

When the time comes for future use, thawing is carried out with utmost care to ensure maximum viability of the frozen sperm. The cryovials or cryostraws containing samples are gently warmed in a water bath at body temperature (37 degrees Celsius), ensuring a gradual transition from extreme cold to
