LD Collins

LD Collins is a specialty pharmaceutical company based in the United Kingdom that focuses primarily on women's healthcare and fertility. The company is best known for developing and commercializing Cyclogest, a progesterone-based treatment used for luteal phase support in assisted reproductive technology (ART), as well as for treating premenstrual syndrome and post-natal depression. In 2011, the company was acquired by the international pharmaceutical firm Gedeon Richter, a move that integrated LD Collins' core products into Gedeon Richter's extensive women's health portfolio. Today, the entity operates as part of the Gedeon Richter group, supporting their global footprint in the fertility and hormone replacement therapy markets.
