Summary Introduction

To determine:

The role of the corpus luteum in a menstrual cycle

Introduction:

Follicular cells in the ovary form a corpus luteum, which is a temporary endocrine glands that secrete both sex hormones, estrogen and progesterone, which inhibit the further release of GnRH, LH and FSH, to prevent the development of any more follicles.

Summary Introduction

To determine:

The role of corpus luteum in early pregnancy.

Introduction:

The corpus luteum is the structure that is formed by the remnants of follicle cells in the ovaries during the luteal phase. It is a temporary endocrine glands that secrete very low level of estrogen and a high level of progesterone. The corpus luteum is typically very large, the size ranges from 2 to 5 cm in diameter.
