Cards

Term
What is the function of the seminal vesicles?
Definition
Adds fluid to the ejaculate to propel the sperm forward. The fructrose secreted by the seminal vesicles provides the energy for sperm mobility
Term
What role does nitric oxide play in erections?
Definition
It involves increased inflow of blood into the corpora cavernosa due to relacation of the travuclar smooth muscle that surrounds the sinusoidal spaces and compression of the veins controlling outflow of blood from the venous plexus
Term
What nervous system controls erection?
Definition
Parasympathetic Nervous system
Term
What are the major sources of estrogen in premenopausal and menopausal women?
Definition
Ovaries and adipose tissue
Term
What hormones would be used to treat exceptionally tall children by effecting early epiphyseal closure?
Definition
Estrogen and testosterone
Term
What describes herniation of the bladder into the vagina?
Definition
Cystocele
Term
What is testicular torsion and what is it a common consequence of?
Definition
A twisting of the spermatic cord that suspends the testis; It is consequence of cryptorchidism along with infertility and malignancy
Term
What is the most common cause of cancer in males between the ages of 15-35?
Definition
Testicular cancer
Term
What cancer is the most common nonskin cancer in the US affecting men 65 years of age and older?
Definition
Prostate cancer
Term
What condition is characterized by heavy bleeding during and between menstrual cycles.
Definition
Menometrorrhagia
Term
What role does oxytocin and prolactin play in a woman’s body?
Definition
Secretion of milk of alveolar cells, which are under the influence of the anterior pituitary hormone prolactin. Milk ejection from the ductile system occurs in response to the release of oxytocin from the posterior pituitary
Term
What are the local effects of progesterone on reproductive organs?
Definition
The glandular development of the lobular and alveolar tissue of the breasts and the cyclic glandular development of the endometrium
Term
What hormone(s) are produced after ovulation when the follicle becomes lutinized as the corpus lutium?
Definition
Estrogen and progesterone
Term
What is usually recognized as the leading cause of osteoporosis?
Definition
Decreased estrogen levels
Term
What is a term for benign neoplasms of smooth muscle in the uterus?
Definition
Leiomyomas
Term
What forms when excess fluid collects between the layers of the tunica vaginalis?
Definition
A hydrocele
Term
What is oogenisis?
Definition
Generation of the primordial ova by mitotic division occurs during fetal life
Term
What is endometriosis?
Definition
The condition in which functional endometrial tissue is found in ectopic sites outside the uterus.
Term
What hormone surge causes ovulation?
Definition
LH
Term
What are causes of male infertility?
Definition
They include: varicocele, ejaculatory dysfunction, hyperprolactinemia, hypogonadotropic hypogonadism, infection, immunologic problems (IE antisperm antibodies), obstruction (including wearing tight jeans), and congenital anomalies
Term
What is stored in the ampulla of the vas deferens?
Definition
Sperm
Term
What are common causes of vaginitis in women of childbearing age?
Definition
Candida albicans, trichomonas vaginalis and bacterial vaginosis
Term
What structure secretes fluid and serves as a buffer and prolongs the life of spermatozoa once they reach the vagina?
Definition
Prostate gland
Term
What is the role of the fructose in seminal fluid?
Definition
Sperm mobility
Term
What is the function of inhibin in males?
Definition
Inhibits FSH production leading to reduction in spermatogenesis
Term
What microorganism causes candidiasis?
Definition
A yeast
Term
What kind of cells does a Pap smear detect?
Definition
Cancerous and precancerous cells
Term
What hormone is responsible for fluid retention in females during PMS?
Definition
Increased aldosterone secretion
Term
What is a complication associated with women having chlamydial infections?
Definition
Pelvic inflammatory disease and infertility or ectopic pregnancy
Term
What are the symptoms associated with trichomoniasis?
Definition
Coious, frothy, malodorous, green or yellow discharge
Term
What is a chocolate cyst and where does it form?
Definition
In the ovary, the endometrial tissue may form cysts (IE endometriomas filled with old blood that resembles chocolate syrup [chocolate cysts])
Term
Define hypospadias.
Definition
A congenital defect urethra is located on the underside of the penis
Term
Describe the functions of testosterone.
Definition
Differentiation of the male genital tract in fetal development, induction of secondary male sex characteristics and promotion of musculoskeletal growth
Term
Describe the causes of scrotal cancer.
Definition
It has been linked to occupation (chimney sweep), poor hygiene and chronic inflammation
Term
Describe testicular torsion? What structures are affected?
Definition
Two risk factors are trauma and strenuous physical activity
Twisting of the spermatic cord that suspends the testes
Term
Describe the luteal stage of the menstrual cycle.
Definition
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
Term
Factors that increase the risk of tubal pregnancy include?
Definition
Pelvic inflammatory disease, therapeutic abortion, tubal ligation or reversal and fertility drugs
Term
What is the greatest danger of tubal pregnancy?
Definition
Tubal rupture
Term
Explain the function cremaster muscles and the pampiniform plexus of the testes.
Definition
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
Term
Why might antibiotic therapy cause vulvovaginal candiasis in females?
Definition
Suppresses the normal protective flora
Term
Which structure in the female anatomy begins to dilate upon parturition (birth)?
Definition
Cervix
Term
When does gonadotrophin-stimulated production of testosterone normally begin?
Definition

Term
How many spermatozoa are produced by one spermatognium in spermatogenesis?
Definition
4
Term
Untreated syphilis might cause complications in what organs?
Definition
Aorta, liver, and central nervous system
Term
High levels of what hormone exert a negative feedback loop on FSH?
Definition
Estrogen
Term
The secretion of FSH and LH are under the control of ____________.
Definition
