This is a congentital defect in males in which there is malpositioing of the erthral opening, it is locatied n the ventral surface of the hypospadias
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?
Parasympathetic Nervous system
What are the major sources of estrogen in premenopausal and menopausal women?
Ovaries and adipose tissue
The secretion of FSH and LH are under the control of ____________.
Gonadotrophin-releasing factor
What hormones would be used to treat exceptionally tall children by effecting early epiphyseal closure?
Estrogen and testosterone
________ is produced and secreted by the interstitial Leydig cells in the testes, while under the influence of luteinizing hormone (LH)
Describe the functions of testosterone.
Differentiation of the male genital tract in fetal development, induction of secondary male sex characteristics and promotion of musculoskeletal growth
The _____________ houses the testes and regulates their temperature.
What describes herniation of the bladder into the vagina?
What is testicular torsion and what is it a common consequence of?
A twisting of the spermatic cord that suspends the testis; It is consequence of cryptorchidism along with infertility and malignancy
What is the most common cause of cancer in males between the ages of 15-35?
Testicular cancer
Describe the causes of scrotal cancer.
It has been linked to occupation (chimney sweep), poor hygiene and chronic inflammation
What cancer is the most common nonskin cancer in the US affecting men 65 years of age and older?
Prostate cancer
A hydrocele forms when excess fluid collects between the layers of the ____________.
Tunica vaginalis
Diabetes mellitus, hypertension, and polycystic ovary syndrome are conditions that alter estrogen metabolism and elevate estrogen levels. Increased estrogen levels are associated with ______________________.
Endometrial cancer
Undesired or harmful effects of supraphysiologic doses of androgens including estrodial and estrone are_________, ___________ and _______________.
Acne, decreased testicular size, azoospermia, and a change in libido
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
__________________ 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?
Estrogen and progesterone
What is a term for benign neoplasms of smooth muscle in the uterus?
What is usually recognized as the leading cause of osteoporosis?
Decreased estrogen levels
During lactation, milk is secreted by ____________________.
Alveolar tissue of the breast
What forms when excess fluid collects between the layers of the tunica vaginalis?
A hydrocele
What is oogenisis?
Generation of the primordial ova by mitotic division occurs during fetal life
A preponderance of evidence suggests a causal link between both cervical cancer, penile cancer and ____________________.

They include: varicocele, ejaculatory dysfunction, hyperprolactinemia, hypogonadotropic hypogonadism, infection, immunologic problems (IE antisperm antibodies), obstruction (including wearing tight jeans), and congenital anomalies
Infertility, malignancy and testicular torsion are long term consequences of ___________________________.
When does gonadotrophin-stimulated production of testosterone normally begin?
Between 10-12 years of age
________________ serves as a storage reservoir for sperm.
