Effects of luteinizing hormone and follicle stimulating hormone on the developmental competence of porcine preantral follicle oocytes grown in vitro

摘要

There has been controversy over the role of FSH in the regulation of preantral follicle development. LH is a survival and differentiation factor that increases oocyte maturation in FSH-supplemented cultures of mouse preantral follicles. However, little information exists on the action of LH and FSH in the developmental competence of porcine preantral follicle oocytes in vitro.
