Endocrine glands play an important role in reproduction by secreting hormones that regulate maturation of follicles, ovulation, and formation and function of the corpus luteum during the menstrual cycle. The corpus luteum secretes progesterone and other hormones to prepare the uterus for potential implantation. During pregnancy, the placenta takes over hormone production from the corpus luteum by secreting human chorionic gonadotropin, human placental lactogen, and pregnancy-specific beta-1 glycoprotein to support the transforming, breast development, and gonadal functions required to maintain pregnancy.

1. Endocrinology in
Relation
To
Reproduction

2.  Endocrine glands play very important
role in the physiology of reproduction.

4. Maturation of Graffian
Follicles
and
Ovulation

5. FSH
LH (small portion)
OESTROGEN (for FSH activity)

6. Follicular
maturation

8.  Corpus luteum  secretes
progesterone
17 α hydroxyprogesterone,
oestradiol, androstenedione

9. PLACENTA

10. At 6 – 8 weeks, there is transfer of
functions of corpus luteum to the
placenta – acts temporarily as new
endocrine organ or power house of
hormone production.

15.  hCG (Human Chorionic Gonadotrophin)
 HPL (Human Placental Lactogen)
 PS β-1 G (Pregnancy Specific β-1
Glycoprotein)
