Sperm Freezing Everything You Need to Know

Sperm freezing is a modern and reliable solution for any man who wants to safeguard his fertility. Whether due to an upcoming medical treatment, high-stress work conditions, or simply as a proactive measure before the age of 40, the process ensures secure, high-quality samples ready for future use. With just a few minutes of collection and rapid vitrification technology, sperm is preserved at –196°C, maintaining full motility and DNA integrity.

What Is Sperm Cryopreservation?

Sperm cryopreservation is the process of collecting, freezing, and storing sperm under specialized conditions so it can be used at a later time. It is intended for men who wish to preserve their fertility for personal use, such as before undergoing treatments or surgeries that may impair sperm production.

At the same time, cryopreservation also enables sperm donation, provided the required medical screening protocol is followed. In donation cases, the sample is quarantined for three to six months depending on the tests conducted by the respective fertility unit. This quarantine ensures the sample is infection-free and safe for the recipient.
The process is painless, simple, and offers long-term benefits.

Why Should a Man Consider Sperm Freezing?

Sperm cryopreservation is a preventive or necessary option in many situations, such as:
Contact Form

Before undergoing chemotherapy or radiotherapy

that may permanently affect fertility

In case of testicular surgery

such as removal due to malignancy

When diagnosed with oligospermia

or declining sperm quality over time

When the man cannot be physically present on the day of egg retrieval

due to work or personal reasons

In cases of difficulty ejaculating at the clinic

where pressure may affect sample collection

Prior to vasectomy

to preserve the ability for future fatherhood

For men requiring surgical sperm retrieval

(e.g., after azoospermia)

When exposed to toxic environmental factors

that could affect fertility

To store donor sperm

for future IVF cycles

When a man wishes to delay fatherhood

and safeguard reproductive potential

How Long Can Sperm Stay Frozen?

The duration of sperm preservation is practically unlimited, provided strict storage conditions are maintained and storage contracts are renewed. Samples can be stored in liquid nitrogen for many years without quality deterioration, allowing men to use them at any future time.
Sperm is thawed only under four specific conditions:
When it's intended for use in assisted reproduction
When the individual formally requests to discontinue storage
In case of non-payment of annual storage fees
According to a valid directive in the person’s will
Choose the storage duration that suits you and preserve your sample for as long as you need.

Treatment Options Using Frozen Sperm

Book a Consultation

Intrauterine Insemination (IUI)

IUI, or artificial insemination, is one of the simplest assisted reproduction methods. It is used when sperm parameters are normal or only slightly compromised. The frozen sample is thawed, processed to isolate motile sperm, and placed directly into the uterus during ovulation. This boosts the chance of natural fertilization and is a painless, quick, and cost-effective option.

In Vitro Fertilization (IVF)

IVF is recommended when mild to moderate male infertility exists or when other fertility barriers are present. The frozen sperm is thawed and processed in the lab to optimize quality before being combined with eggs in controlled conditions. If fertilization occurs, the best embryos are selected and transferred into the uterus. This widely used method yields high success rates.

IVF with Intracytoplasmic Sperm Injection (ICSI)

ICSI is mainly used in cases of severe male infertility, such as azoospermia or very low sperm motility. The thawed sample is carefully analyzed to select the best sperm cell, which is then injected directly into the egg via micromanipulation. This technique overcomes natural barriers and increases the chance of fertilization. ICSI has helped many couples achieve parenthood when other methods failed.

The Sperm Freezing Process

Step 1

Detailed Information and Consent

The process begins with a personal consultation at the FertUlity clinic. All stages of the procedure, potential benefits, and risks are explained in full detail. The individual then signs the required consent and declaration forms, indicating the desired storage duration. Any questions are answered on the spot to ensure complete understanding.
Step 2

Sperm Evaluation and Lab Testing

During the initial visit, the man states the reason for sperm preservation and undergoes a quality analysis of the sample. Blood tests are also conducted to screen for sexually transmitted infections. These tests include hepatitis B and C, HIV, and syphilis. This screening is vital for ensuring the safety of the sample before freezing.
Step 3

Result Delivery and Data Management

Results are shared exclusively with the individual who provided the sample unless written consent has been given to share with a partner. FertUlity prioritizes confidentiality and proper management of personal data. If requested, an official report can also be sent to the patient’s treating physician to ensure continuity of care.
