Hamilton Thorne Launches IMSI STRICT(TM) Analysis Software at ESHRE 2011 for Fertility Markets

BEVERLY, MA and TORONTO--(Marketwire - Jun 27, 2011) - Hamilton Thorne Ltd. (TSX-V: HTL), a leading provider of advanced laser systems for the regenerative medicine, fertility and stem cell research markets, today announced the launch of its IMSI STRICT™ morphology analysis software for the clinical and fertility markets. IMSI STRICT™ will be unveiled during the 27th Annual Meeting of the European Society of Human Reproduction and Embryology (ESHRE) taking place in Stockholm, Sweden, July 3-6, 2011.

A commonly used fertility procedure is called intracytoplasmic sperm injection (ICSI), in which sperm from an infertile male is injected directly into the woman's eggs. Research has shown that better results are achieved when the laboratory chooses the optimum sperm to inject. Hamilton Thorne is launching IMSI STRICT™, an imaging analysis product that provides fertility clinicians with the ability to select optimum sperm and thus improve outcomes during ICSI procedures. The process of choosing the sperm with the best morphology is termed intracytoplasmic morphologically selected sperm injection (IMSI).

Sperm morphology was researched at Tygerberg Hospital in Cape Town, South Africa, by Dr. Thinus Kruger and his team who defined STRICT Criteria. They classified stained, non-living sperm according to their physical characteristics by applying STRICT Criteria. The World Health Organization (WHO) has accepted STRICT Criteria morphology as the preferred standard for sperm classification and selection. Hamilton Thorne implements the principles of STRICT Criteria morphology in its IMSI STRICT™ analysis. This allows living sperm to be evaluated and the best cells to be selected for fertilization. Current research in the field supports that STRICT Criteria provides the best possible outcomes. Hamilton Thorne has collaborated with PrimeLogic, a software engineering company in South Africa, to implement the IMSI STRICT™ analysis product.

"In the fertility markets, IMSI is becoming a key procedure to improve outcomes in fertility treatments," said Diarmaid Douglas-Hamilton, Chief Technology Officer of Hamilton Thorne Ltd. "We believe that our IMSI STRICT™ product will represent a significant step forward in the sperm selection process and provide scientists and patients with better solutions for their conception goals. The speed of the IMSI STRICT™ analysis should yield real-time results to enhance the work flow efficiency."
