Male fertility

Modern diagnostic approach of male infertility

Sperm Cryopreservation

Semen freezing and cryopreservation is a laboratory procedure during which semen is stored at ultra low temperature conditions, in order to be kept for long periods and be used at a later time in assisted reproduction.

The progress of biomedical sciences offers now the possibility to protect male fertility potential from these negative perspectives by ‘freezing’ time. A way to secure a man’s possibility to procreate at any time in life he feels ready is by Sperm Freezing and Cryopreservation.

Advanced Seminology Applications

The modern diagnostic approach of male infertility requires personalization and evidence-based applications. In addition to conventional sperm parameters (sperm count, concentration, sperm motility), the in-depth evaluation of sperm fertility potential is now supported by a series of laboratory tests.

How well do you know your fertility?

A quick quiz that reveals how informed you are about the factors that affect male fertility. Myths, truths, and small surprises that help you understand your body better and make more informed choices for your future.

Did you know that, unlike oocytes—which are all produced during embryonic life—approximately 1,500 sperm cells are produced and mature every second throughout the life of the average man after puberty?

Did you know that, although men do not experience an abrupt cessation of fertility like women do with menopause, advancing age appears to significantly affect male fertility?

Did you know that sperm maturation is a complex process that lasts almost three months and is significantly influenced by a man’s health and lifestyle habits during that period?

Did you know that a sedentary lifestyle, smoking, alcohol consumption, substance use, anabolic steroid use, stress, and poor nutrition can all be harmful factors for male fertility?

Did you know that approximately 1 in 5 couples will experience difficulty conceiving, and that male factors are involved in about half of infertility cases?

Did you know that most men neglect preventive semen analysis and andrological–urological evaluation, resulting in living for years with conditions that may negatively affect fertility?

Did you know that at Cryogonia you can obtain a valid and comprehensive assessment of both the basic and functional parameters of your semen, through the expertise of highly specialized scientists, under the supervision of a strict external quality control system?

What are the costs of the procedure?2025-05-26T20:10:04+03:00

Semen testing and freezing is charged with a total sum which is relative to the total number of collected samples – there is a discount in case more than one samples are collected.

The cryopreservation costs are determined on a monthly basis and cover all cryopreserved samples.

Thawing and transport costs are also charged to the patient.

How can I use my frozen semen samples?2025-05-26T20:08:58+03:00

When you are ready to use your cryopreserved semen for an assisted reproductive method, you must notify the Sperm Bank as soon as possible, preferably 1-2 weeks before the scheduled attempt.

The semen sample can be transferred to any doctor or fertility clinic you specify on a written special consent form.

What happens during thawing?2025-05-26T20:08:01+03:00

During thawing, some of the frozen spermatozoa do not survive. The recovery of functional spermatozoa that survive the freeze-thawing cycle depends on the endogenous endurance of each semen sample and cannot be predicted with certainty.

What happens after the sample collection?2025-05-26T20:07:05+03:00

Every semen sample is carefully identified using a special coding system and labeling, which ensures the precise traceability and confidentiality of the data. Each sample is labeled with the patient’s name, a unique code and the date of freezing.

A small aliquot of every semen sample is examined with regard to the basic sperm parameters before freezing, i.e.:

  • Semen volume
  • Sperm motility
  • Motility index

The rest of the sample is diluted with a special cryoprotectant medium, which protects the biological properties of the spermatozoa during the freezing process.

The sample is gradually put in special freezing containers (straws or paillettes) at several aliquots of low volume (0.5 ml). The total number of straws depends on the total volume of the semen sample.

The freezing process starts directly after the straw filling and is performed using a semi-automated system which permits the gradual temperature decrease from room temperature to ultra low levels (< 0 °C). This step protects the spermatozoa from the damage that an abrupt temperature fall would cause.

At the end of the freezing cycle, the samples are submerged in liquid nitrogen and then placed in special long term cryopreservation tanks.

Semen may be preserved at a final temperature of -196 °C indefinitely. CRYOGONIA Sperm Bank offers semen cryopreservation for long time periods, following the patient’s consent and its renewal at regular intervals.

How are semen samples collected?2025-05-26T20:04:53+03:00

Semen samples may be collected in a special, comfortable room located in the Sperm Bank. In case the patient is in the hospital, it is also possible that an authorized person can transfer the samples with specific appointment.

You are advised to arrange an appointment before your visit to the Sperm Bank. Specific instructions regarding the sample’s collection and transfer are provided by the personnel of CRYOGONIA during the phone communication.
