Segmentation by type focuses on the molecular origin and delivery format of recombinant hCG products, delineating three core sub‑categories. The first, recombinant hCG, derived from genetically engineered CHO cells, dominates the market due to its high purity, batch‑to‑batch consistency, and reduced immunogenicity, thereby capturing the majority of the revenue share. The second, biosimilar recombinant hCG, emerges as a cost‑effective alternative following patent expirations; it leverages similar amino‑acid sequences but may exhibit minor variations in glycosylation, influencing pricing dynamics and market penetration in price‑sensitive regions. The third, combination dosage forms, integrates hCG with adjunctive agents such as follicle‑stimulating hormone (FSH) in a single injection, facilitating streamlined protocols for ART clinics. Each type contributes uniquely: recombinant hCG underpins the bulk of sales, biosimilars drive volume growth in emerging economies, and combination products expand the addressable patient base by simplifying treatment regimens. This taxonomy clarifies how product‑type differentiation shapes overall market size and competitive positioning.
