Answer: Lutenizing hormone.
Step-by-step explanation:
Luteninzing hormone is a hormone that is produced by the gonadotropic cells present in the anterior pituitary gland.
In case of females the level of lutenizing hormone increases and triggers ovulation. The development of corpus lutem also takes place by the help of this hormone.
Hence, the hormone responsible for ovulation and conversion of follicle into corpus luteum is lutenizing hormone.
