Hamilton Sperm VD (vitrification device)

Hamilton Sperm VD (vitrification device)

A novel solution of cryopreservation of very low numbers of spermatozoa aims to maximize fertility perseveration for males.

Cryopreservation of sperm cells is mandatory in cases of azoospermia/severe oligozoospermia. The routine methods for sperm freezing are not suitable for freezing small numbers of spermatozoa. Most of the sperm cells will not be found after thawing in cases of rare spermatozoa.

An optimal device for freezing small numbers of spermatozoa will avoid unnecessary TESE (Testicular Sperm Extraction) procedures. An optimal device for freezing small numbers of spermatozoa will give a good chance for males with severe oligozoospermia to preserve their fertility potential.

Features

• Optimal recovery of cells.
• No loss of cells after thawing.
• Motility and viability of the thawed cell is unaffected.
• Optimal cryopreservation after TESE procedure will avoid unnecessary surgical sperm recovery.
• Males with severe oligozoopermia will be able to preserve their fertility potential .
• Ease of use for the IVF laboratory staff.

Two major targets are:

1- Azoospermic patients who have undergone a TESE/micro-TESE procedure which yielded a small number of spermatozoa. These can now be split between several SpermVD devices, allowing thawing of the necessary amount for each OPU, thus maximizing fertility preservation.

› The potential market for azoospermic patients who require TESE is 84,000* SpermVD units a year.

2- Severe oligozoospermia/Virtual azoospermia patients - In conjunction with the extended search technique, the SpermVD allows creation of a backup in case fresh spermatozoa will not be found in the ejaculate on OPU day.

› The potential market for this opportunity is approximately 28,000* units a year.
