Follicle-stimulating hormone (FSH) is an endogenous glycoprotein hormone. This hormone is of significant importance in the field of assisted reproduction. Gensci has successfully developed Jin Sai Heng, the first domestically-produced recombinant human follicle-stimulating hormone genetic engineering drug. The need for assisted reproduction has soared in recent times due to shifting societal patterns, such as delaying marriage and childbearing age. Additionally, various environmental factors have contributed to the rise in infertility cases. As a result, the market potential for assisted reproduction procedures is expected to witness significant growth in the near future.
