What condition is characterized by heavy bleeding during and between menstrual cycles.
Describe the luteal stage of the menstrual cycle.
After ovulation, the follicle collapses, and the luteal stage of the menstrual cycle begins. The granulose cells are invaded by blood vessels and yellow lipochrome-bearing cels from the theca layer.

The glandular development of the lobular and alveolar tissue of the breasts and the cyclic glandular development of the endometrium
What role does oxytocin and prolactin play in a woman's body?
Secretion of milk of alveolar cells, which are under the influenced of the anterior pituitary hormone prolactin. Milk ejection from the ductile system occurs in response to the release of oxytocin from the posterior pituitary
__________________ is an abnormal, painful, sustained erection that can lead to ischemic damage of penile structures.
What hormone(s) are produced after ovulation when the follicle becomes lutinized as the corpus lutium?

Describe testicular torsion? What structures are affected?
Two risk factors are trauma and strenuous physical activity
Twisting of the spermatic cord that suspends the testes
What is endometriosis?
The condition in which functional endometrial tissue is found in ectopic sites outside the uterus.
Factors that increase the risk of tubal pregnancy include? What is the greatest danger?
