Identifying and isolating rare sperm

Medical background:

In the medical case of NOA – Non Obstructive Azoospermia, when no sperms are found in a regular microscopic examination, a massive over-all search of the semen is required, as a stage prior to a testicle operation of the TESA/TESE/MicroTESE kind.

About Cytobit:

The Cytobit laboratory is located in Tel-Aviv, ISRAEL, and is recognized by the Israeli Ministry of Health. The laboratory specializes in identifying and isolating rare sperm in azoospermic men.

The laboratory staff has proven experience of over 20 years in the biology field – IVF, and in the physics field – optics.

The laboratory provides services to patients in Israel, and to those who come from abroad and intend to take the sperm and continue the treatment, in the IVF unit in their country.

Quality Management System:

We have been awarded ISO 9001:2015 certification.


Identifying the Sperm:

The identifying of the sperm is done either in the ejaculate, or in the testicular tissue from a TESA/TESE operation. This is done using advanced separation technologies, and a meticulous scanning system in all of the semen volume, with an enhanced designated microscope.

For the purpose of identification, we have developed an innovative system for automatic cells identification, based on artificial intelligence, which works parallel and as a backup to a scan search through the microscope eyepieces.

Isolating Sperm:

At the end of the scan, all those living sperms that have been marked are retrieved by a micromanipulator device from the sample, to one of the following options:

In a search for the day of the oocytes retrieval – into an IVF petri dish, ready to be transferred to the continuance of the fertilization in ICSI in the IVF unit. The search is coordinated to end in time for the oocytes retrieval.

In a search for the purpose of Freezing the sperm – into a test tube TIP, for freezing and quarantining the sperm in a sperm bank.

Single Sperm Freezing:

The technique for cryopreservation of single or small number of human spermatozoa, is done in a 'volume reducer' device of a TIP test tube. The device locks the sperm cells in a low medium volume, which saves the effort of performing another sperm search upon the thawing process.
