The heterogeneity of gonadotropins exists in two forms, macroheterogeneity, which results from the absence of one or two oligosaccharide chains in the ß-subunit, and microheterogeneity which results from variation in the structures and complexity of the glycans attached to the hormone. In the clinical arena, FSH compounds are widely used by fertility specialists to promote ovarian follicle growth and maturation to a preovulatory follicle containing a fertilization-competent oocyte. Several genetically engineered recombinant human FSH preparations have been added to the arsenal of follitropin preparations in several countries for the treatment of infertility, particularly in women attending assisted reproduction clinics. Although the primary structure of these recombinant proteins is identical to that of naturally occurring FSH, the cell context and variations in the production and purification processes may impact the glycosidic profile of the recombinant FSH macro- and micro-heterogeneity, which may potentially influence the pharmacokinetics and pharmacodynamics of the compound. This review concentrates on the structure-function correlates of follitropin, with emphasis on the physiological and biological importance of the carbohydrates attached to its protein core, including its pharmacokinetics and biological activity.
