Male Reproductive System Quiz

Study Notes

Male Reproductive System

Ureter and Urinary Bladder are part of the urinary tract, along with the Rectum.
Seminal Vesicle contributes to seminal fluid production; normal semen volume is between 3 to 5 mL per ejaculation.
Sperm count ranges from 20 million to 150 million per mL; Clomid can be prescribed to increase sperm production.
Oligospermia is diagnosed with a sperm count below 20 million; Aspermia is characterized by the absence of sperm.
Lifespan of sperm is typically 3 to 5 days, with viability in the fallopian tube lasting up to 27 hours.
Sperm morphology (shape) affects fertility; optimum motility and viability percentages should be monitored.
Prostate cancer is the most prevalent cancer in males; Viagra is prescribed for erectile dysfunction by increasing blood flow.
Vasectomy involves cutting and ligating the vas deferens; men may still have erections and ejaculate, but semen will be sperm-free.

Female Reproductive System

Female gonads are the ovaries; they are responsible for producing ova.
The vagina is the female counterpart to the penis; the glans clitoris corresponds to the glans penis.
Leydig cells nourish sperm cells by providing glucose and fructose; sperm maturation occurs in the epididymis.
Seminal fluid production: Epididymis (5%), Seminal Vesicle (30%), Prostate Gland (60%), and Bulbourethral Gland (remaining 5%).
Alkaline secretions from the prostate and bulbourethral glands neutralize acidity, optimizing sperm health.
The ampulla is located beside the seminal vesicle and connects to the ejaculatory duct.

Fertility and Contraception

Pre-seminal fluid can lead to pregnancy; withdrawal method has an 80% effectiveness rate.
Male urethra serves dual purposes: urine excretion and semen passage; it is not highly muscular.
Erect penis averages 4 to 5 inches in length; size can influence sperm viability and entry into the cervix.

Uterine Positions

Anteverted uterus tilts slightly forward; Anteflexion is sharply leaning forward.
Retroverted uterus appears normal in early pregnancy; Retroflexion is considered an abnormal position.
Abdominal palpation technique for uterine assessment involves a "high five" hand position.

Oxytocic Medications

Oxytocics stimulate uterine contractions; Syntocinon and Oxytocin are examples used when labor is imminent.
Methergine is contraindicated before delivery due to the risk of continuous contractions, which can cause cervical closure.
Monitoring blood pressure is crucial when administering oxytocics; hold the medication if BP reaches 140/90.
Smooth muscle relaxants like Duvadilan, Dactyl OB, and Terbutaline (Bricanyl) are used to prevent labor contractions.

Miscellaneous

Skene's gland lubricates the urethral opening, while Bartholin's gland lubricates the vaginal opening.
Understanding the physiological processes and hormonal influences is key for fertility assessments and reproductive health management.
