The Follicular phase
Follicular growth and preparation for ovulation 
-
Dynamics of the antral follicle consist of: recruitment (emergence), selection, dominance, atresia

-
FSH and LH exert different effects on follicles. Their secretion rates are controlled differently

-
The 2- Cell, 2- Gonadotropin model describes estrogen synthesis
Major effects of estradiol on the reproductive tract are: increased blood flow, genital swelling, change in tissue electrical conductivity, leukocytosis, increased mucosal secretion, initiation of uterine gland growth, elevated myometrial tone
Ovulation
Ovulation is brought about by: elevated blood flow, breakdown of connective tissue, ovarian contractions
-
-
-
Oocyte growth involves formation of a large cytoplasm and the zona pelucida
-
-
Elevated gonadotropin secretion from the anterior lobe of the pituitary
The tonic and surge centers in the hypothalamus control GnRH release. The surge center responds dramatically to high blood concentrations of estradiol
