About OvaScience
OvaScience (NASDAQ: OVAS) is a global
fertility company dedicated to improving treatment options for women
around the world. OvaScience is discovering, developing and
commercializing new fertility treatments because we believe women
deserve more options. Each OvaScience treatment is based on the
Company’s proprietary technology platform that leverages the
breakthrough discovery of egg precursor (EggPCSM) cells –
immature egg cells found inside the protective ovarian lining. The
AUGMENTSM treatment, a fertility option specifically designed
to improve egg health, is available in certain IVF clinics in select
international regions. OvaScience has commenced a non-commercial
preceptorship training program with the OvaPrimeSM treatment,
which could increase a woman’s egg reserve, and is developing the OvaTureSM treatment,
a potential next-generation IVF treatment that could help a woman
produce healthy, young, fertilizable eggs without hormone injections.
OvaScience treatments are not available in the U.S. For more
