function of the seminal vesicles
Adds fluid to the ejaculate to propel the sperm forward. The fructrose secreted by the seminal vesicles provides the energy for sperm mobility
the function of the cremaster muscles and the pampiniform plexus of the testes
The paminform plexus adsorbs heat from the arterial blood cooling it as it enters the testes. The cremaster muscles, which respond to decrease in testicular temperature move the testes closer to the body
Role of nitric oxide in erections
It involves increased inflow of blood into the corpora cavernosa due to relacation of th etravuclar smooth muscle that surrounds the sinusoidal spaces and compression of the veins controlling outflow of blood from the venous plexus
What nervous system controls erection?

In order for embryonic gonads to become testes, what is required?
A Y chromosome
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. A arapid accumulation of blood and fluid forms a mass called the corpus luteum. During the luteal stage, progesterone is secreted from the corpus luteum
What are the local effects of progesterone on reproductive organs?
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
