In Canada, the main three injectable medications, in alphabetic order, are Gonal F, Menopur, and Puregon. In different countries, they will have different names (in the USA for example Puregon is called Follistim) but worldwide these are the three leading products.
Gonal F and Puregon are synthesized in the lab. Menopur, however, is a human urine-derived product. And therein lies its strength, and its potential weakness.
