Merional is a pharmaceutical preparation containing human menopausal gonadotrophin (hMG), i.e. a balanced mix of the natural follicle follicle stimulating hormone (hFSH) and luteinising hormone (hLH).
The hMG is a hormonal mix used to stimulate follicular development in women, and sperm formation and maturation in men or as a substitution therapy in hypogonadic patients.
Merional should be clearly distinguished from old generation hMGs, which contained FSH together with LH just because of the low purification that did not allow to separate FSH from LH as well as from many other impurities. The new technology of IBSA allows to purify FSH and LH by two separate processes. The two hormones are then mixed together to obtain pure hMG to be used any time the benefit of LH stimulation is needed beside plain FSH stimulation (Fostimon).
Due to its level of purity, Merional may be administered subcutaneously.
Merional is available in vials of 75 or 150 IU and is intended for administration under strict medical control.

The advantages of Merional may be summarised as follows:

• Improved safety and efficacy
• Reliability, meaning consistency between labelled and actual content
• Batch-to-batch consistency, ensuring that there are no changes from a production batch to another
• Subcutaneous self-administration
• Affordable cost, comparable to that of old-generation products
