Q

perineum

Study These Flashcards
A

external region between the anus and scrotum

23
Q

prostate gland

Study These Flashcards
A

exocrine gland a base of male urinary bladder
- secretes fluid part of semen into urethra during ejaculation

24
Q

scrotum

Study These Flashcards
A

external sac that contains the testes

25
semen
spermatozoa and seminal fluid discharged from the urethra during ejaculation
26
seminal vesicles
paired sac like exocrine glands that secrete fluid into the vas deferens
27
seminiferous tubules
narrow, coiled tubules that produce sperm in the testes
28
spermatozoon
sperm cell
29
sterilization
procedure that removes a person's ability to produce or release reproductive cells through removal of testicles, vasectomy, or oophorectomy
30
stromal tissue
supportive, CT or an organ
31
testis
male gonad that produces spermatozoa and teststerone
32
testosterone
hormone secreted by interstitial tissue of the testes - responsible for male sex characteristics
33
vas deferens
narrow tube carrying sperm from the epididymis toward the urethra - aka ductus deferens
34
hydrocelel
buildup of fluid in the sac around the testicle - causing swelling in the scrotum
35
testicular torsion
when the spermatic cord twists, cutting off blood flow to the testicle - severe pain, swelling, nausea, and vomiting
36
varicocele
enlargement of the veins within the scrotum (like varicose veins) - causes dull ache or discomfort
37
prostate gland
walnut sized gland located below the bladder and in front of the rectum - produces fluid that mixes with sperm to form semen
38
prostate carcinoma
most common type of cancer among men
39
benign prostatic hyperplasia (BPH)
non-cancerous enlargement of the prostate gland that commonly occurs as men age
40
hypospadias
congenital condition where the opening of the urethra is located on the underside of the penis instead of the tip
41
chlamydia
infection caused by bacterium chlamydia trachomatis via sexual contact - can infect urethra, cervix, rectum and throat - can lead to pelvic inflammatory disease
42
gonorrhea
infection caused by bacterium neisseria gonorrheae via sexual contact - affects urethra, cervix, rectum, and throat - symptoms- painful urination, abnormal vaginal discharge
43
herpes genitalius
STI caused by herpes simplex virus - causes painful sores or blisters on genitals, anus or mouth
44
human papillomavirus
group of virus that infect the skin and mucous membranes mainly via sexual contact - can cause genital warts, cervical cancer, and other cancers of genitals, anus, mouth, and throat
45
syphilis
bacterial infection caused by treponema pallidum via sexual contact -starts as painless sores and can affect multiple organs
46
prostate specific antigen test
measures level of prostate specific antigen in a man's blood
47
normal PSA levels
below 4.0 nanograms per milliliter
48
elevated PSA levels
additional testing like more PSA tests, imaging, or prostate biopsy
49
semen analysis
assesses male fertility and reproductive health
50
semen analysis test measure
- volume- amount of semen - concentration- number of sperm cells present per mL - motility- % of sperm cells that are moving and quality of movement - morphology- size and shape of sperm cell, % sperm with normal shape - viability- % of live sperm cell in sample
51
semen analyzed for
- infertility - before assisted reproduction procedures - after vasectomy - monitoring treatment
52
transurethral resection of the prostate (TURP)
surgical procedure used to treat benign prostatic hyperplasia - removal of portions of prostate gland that are obstructing flow of urine through urethra
53
vasectomy
surgical procedure for male sterilization where vas deferens are cut, tied off, or sealed
