SPERM FREEZING
Sperm Freezing at Nicosia Fertility
At Nicosia Fertility, we understand the profound importance of planning for the future. Sperm freezing, also known as sperm cryopreservation, is a reliable and scientifically proven method to preserve male fertility for those facing medical treatments, career demands, or personal circumstances. Whether safeguarding fertility due to health concerns or planning ahead for family-building goals, sperm freezing provides the flexibility and assurance needed to navigate life’s uncertainties.
What is Sperm Freezing?
Sperm freezing is a process in which a man’s sperm is collected, analyzed, and preserved at ultra-low temperatures to halt biological activity. By storing sperm at -196°C in liquid nitrogen, its viability remains intact indefinitely, allowing it to be used for reproductive purposes at any time in the future. First successfully utilized in 1953, sperm cryopreservation has facilitated countless pregnancies and is now a well-established part of reproductive medicine.
Frozen sperm can be used in various assisted reproductive treatments such as intrauterine insemination (IUI), in vitro fertilization (IVF), or intracytoplasmic sperm injection (ICSI). It’s a simple yet powerful option for men wishing to ensure their reproductive potential is preserved.
Who Should Consider Sperm Freezing?
Sperm freezing is a viable option for many individuals facing diverse situations:
-
Cancer Treatment: Chemotherapy, radiation, and surgeries such as prostate or testicular removal can impair sperm production and quality. Freezing sperm beforehand ensures future fertility is not compromised.
-
Chronic Health Issues: Conditions like autoimmune disorders, cystic fibrosis, or prolonged steroid use may affect sperm quality over time.
-
Risk of Infertility from Surgeries: Procedures involving the reproductive or urinary tracts may inadvertently impact fertility.
-
-
Pre-Vasectomy: Men planning sterilization can store sperm as a backup in case family planning decisions change later in life.
-
High-Risk Occupations: Those working in hazardous environments such as the military, law enforcement, or industries with chemical or radiation exposure can preserve sperm before facing potential risks.
-
Advanced Age: As male fertility naturally declines with age, freezing sperm at a younger age ensures access to higher-quality samples for future use.
-
-
Busy Professionals: Men unavailable during a partner’s fertility treatment cycle can ensure their sperm is ready and accessible when needed.
-
Same-Sex Couples and LGBTQ+ Individuals: Sperm freezing supports reproductive goals for couples or individuals planning family-building with the help of donor eggs or gestational surrogates.
-
Couples Undergoing Fertility Treatments: Couples undergoing IVF or IUI can utilize previously frozen sperm for insemination or to fertilize retrieved eggs in cases where the male partner is unavailable to provide a fresh sample at the time of the procedure.
-
Benefits of Sperm Freezing
Sperm freezing offers several unique advantages:
Properly stored sperm remains viable for decades, providing flexibility and security for future family planning.
Long-Term Viability
Knowing that fertility is preserved can ease anxiety during life’s more challenging moments.
Peace of Mind
Sperm frozen at a younger age ensures higher quality and better motility, which contribute to successful pregnancies.
Preserving Younger Sperm
Compared to other fertility preservation methods, sperm freezing is affordable and efficient.

The Sperm Freezing Process
The process of sperm freezing is straightforward and required undergoing blood testing as an initial step, primarily to screen for HIV, hepatitis B, and hepatitis C. It involves a few key steps:
-
Most men provide a semen sample through ejaculation in a private, comfortable environment at the clinic or at home with proper guidance. For those unable to ejaculate, surgical sperm extraction directly from the testicles may be performed.
-
To ensure an optimal sample, men are advised to abstain from ejaculation for 2–5 days before collection. If ejaculation occurred too recently, the sperm count might be lower. Conversely, if there has been a prolonged gap since the last ejaculation, many sperm may lack motility.
-
-
Laboratory specialists evaluate the sample for key parameters such as sperm count, motility, morphology, volume, viscosity and pH levels.". A single ejaculation can contain anywhere from 40 million to 600 million sperm, depending on the volume of the semen and the time elapsed since the previous ejaculation. This step ensures the sample is suitable for freezing.
-
-
A cryoprotectant is added to the semen to protect sperm cells from damage during the freezing process. Two techniques are commonly used:
-
Slow Freezing: Gradually reduces the temperature over several hours to prevent ice crystal formation.
-
Vitrification: A rapid freezing method that flash-freezes the sperm, preventing ice crystals and preserving cellular integrity.
-
-
Samples are then stored in liquid nitrogen tanks at -196°C.
-
-
Thawing sperm is just as crucial as the freezing process, requiring careful handling to allow the cells to regain their normal biological functions while avoiding sudden temperature changes. Cryopreservation protocols typically involve a controlled thawing temperature of 37 degrees Celsius. Although higher temperatures could speed up the process, they are avoided to minimize the risk of cellular damage. When needed, the sample is thawed using controlled methods to restore biological activity. Cryoprotectants are carefully removed, and the sperm is prepared for use in reproductive treatments such IVF or IUI.

Risks of Sperm Freezing
While sperm freezing is a safe and well-established practice, certain risks and considerations include:
1
Sperm Loss During Thawing
A small percentage of sperm may not survive the freezing and thawing process. However, the remaining viable sperm are typically sufficient for successful fertility treatments.
2
Cryopreservation Damage
Ice crystal formation or osmotic shock during freezing may affect sperm structure or function, but these issues generally do not impact pregnancy success rates.

Sperm freezing, also known as cryopreservation, preserves a man’s fertility by storing sperm cells in liquid nitrogen for future use in treatments like IVF or artificial insemination.
Men undergoing cancer treatments, vasectomies, or high-risk surgeries, as well as those in dangerous professions or with low sperm quality, can benefit from preserving their sperm.
After collecting a semen sample, it is analyzed for quality and treated with cryoprotectants to prevent damage during freezing. The sample is then stored in liquid nitrogen for future use.
Sperm freezing offers a long-term and affordable way to preserve fertility, ensuring future family planning options with minimal annual storage costs.
Sperm freezing is a well-established, safe procedure. While not all sperm survive the freezing and thawing process, enough healthy sperm typically remain for successful fertilization.
Cryopreserved sperm can be stored indefinitely with no known limit. Successful pregnancies have been achieved even after 20 years of storage.
Yes, sperm freezing is a common method for preserving donor sperm, which can later be used to help individuals or couples facing infertility challenges.
The sperm is gradually warmed to preserve its integrity and then washed to separate it from the cryoprotectant, preparing it for use in fertility treatments.
While some sperm may not survive the freezing and thawing process, the majority retain their fertility potential, leading to successful pregnancies.
Sperm freezing allows men to safeguard their fertility before undergoing medical treatments or making life decisions that could affect sperm quality, offering flexibility and peace of mind for future family planning.
