The art of semen preservation

Towards maximum viability and fertility

In October 2020, Barex Biochemical Products and HuVeSearch started a partnership

In October 2020, Barex Biochemical Product and HuVeSearch (www.huvesearch.com) started a partnership to capitalize on the preservation media that were developed by Barex Biochemical Products.

HuVeSearch brings wide marketing and sales expertise and a broad network in the artificial insemination business.

Barex Biochemical Products developed extenders for several animal species and has focused the past years on equine semen extenders and brought the equine Hippex extenders successful to the market (www.hippex.net).

Combining the research capabilities of Barex Biochemical Products and the marketing and sales expertise of HuVeSearch will benefit both parties.

Barex Biochemical Products can now focus more on research, while HuVeSearch is responsible for the production and sales of the preservation media.

The equine preservation media are the cornerstone of the partnership, but the cooperation will also include semen preservation media for other species.

Research Projects

Semen Cryo Concentrate

The purpose of the Cryo Concentrate project is to develop a fluid that contains high concentrations of cryoprotectants. The Cryo Concentrate has the following properties.

  1. The concentrate can be shipped worldwide at ambient temperatures (as opposed to many commercial cryopreservation media).

  2. The concentrate can be used to prepare an equine freezing extender by adding a small amount of the concentrate to an existing extender for fresh or chilled sperm cell preservation.

  3. The concentrate will be developed for equine semen freezing, but can be applicable to extenders of other animal species as well.

 

The project is currently in its final phase.

Semen Vitrification

The purpose of the Vitrification Project is to develop a method for ultra-rapid freezing of equine semen diluted in Vitrex (our proprietary equine semen vitrification medium).

The feasibility of Vitrex for equine semen vitrification has been shown by a collaborative study with the research group of Prof. Manuel Hidalgo of the University of Cordoba, Spain. 

Using Vitrex, a total motility of over 60% and a viability of over 70% can be seen after warming of vitrified equine semen.

Our goal is to improve and simplify the vitrification procedure to become more efficient and usable on a large-scale day-to-day basis.

The advantages of vitrification over the current routine slow-freezing are several: vitrification is easier, quicker and much less expensive.

Moreover, Vitrex can be supplied as powder and can be shipped at ambient temperature.
