==Introduction==
Luteinisation occurs after ovulation and the collapse of the follicle.
The number of [[The_Ovary_-Corpus_Luteum_-_Anatomy_%26_Physiology|corpora lutea]] formed in the ovary at any one time is directly proportional to the number of oocytes ovulated. Therefore many [[The_Ovary_-Corpus_Luteum_-_Anatomy_%26_Physiology|corpora lutea]] will be visible on the ovary of [[Gestation_-Litter_Sizes_-_Anatomy_%26_Physiology|polytocous]] animals. During Luteinisation there is an increase in both the size and weight due to hyperplasia (increase in cell number) and hypertrophy (increase in cell size) within the developing [[The_Ovary_-Corpus_Luteum_-_Anatomy_%26_Physiology|corpus luteum]].

Control of [[The_Ovary_-Corpus_Luteum_-_Anatomy_%26_Physiology|corpus luteum]] formation and development aswell as the production of [[Endocrine_System_-_Ovaries_-_Anatomy_%26_Physiology#Progesterone|Progesterone]] by luteal cells is regulated principally by Luteinising Hormone.
