Exclusive technology

Recognizing the important role of the high glycosylation subtype in the FSH family, IBSA has developed and patented a non-invasive purification system to obtain the highest purity of various FSH subtypes.

Natural startup

The highest purity FSH of IBSA is rich in high glycosylation (acidic) subtypes. In the natural cycle, these subtypes predominate early in the follicles and are important for effective recruitment and optimal maturation of oocytes.

Reliable curative effect

More than 20 years of clinical experience and randomized controlled clinical studies have demonstrated that Fostimen is an effective and reliable FSH preparation.
