Male Urogenital & Reproductive Disorders: Hypospadias, Infertility & Sexually Transmitted Infections
High-yield memory reinforcement for rapid KMU revision.
1. High-Yield Flashcards
Tap each question to reveal the answer.
How is hypospadias classified clinically?
By the position of the urethral meatus: distal, mid-penile or proximal.
What penile deformity commonly accompanies significant hypospadias?
Chordee, producing ventral penile curvature.
What foreskin appearance is commonly associated with hypospadias?
A dorsal hood caused by deficient ventral preputial development.
Why should circumcision be avoided before specialist assessment in hypospadias?
Preputial tissue may be useful during reconstructive surgery.
What are the main goals of hypospadias repair?
Straighten the penis and create a functional urethral opening in an appropriate position.
What postoperative complication can produce urine leakage from an abnormal opening after hypospadias repair?
Urethrocutaneous fistula.
What postoperative problem is suggested by a thin urinary stream after hypospadias repair?
Meatal or urethral narrowing.
What three broad categories organize causes of male infertility?
Pre-testicular, testicular and post-testicular causes.
What is the key initial laboratory investigation in male infertility?
Semen analysis.
What does azoospermia mean?
Absence of sperm in the ejaculate.
What does oligozoospermia indicate?
Reduced sperm concentration.
What does asthenozoospermia indicate?
Reduced sperm motility.
Which three parameters are central when interpreting semen quality?
Sperm concentration, motility and morphology.
Which genital lesion pattern suggests herpes infection?
Painful grouped vesicles that may progress to shallow ulcers.
Which genital lesion pattern is classically associated with primary syphilis?
A typically painless genital ulcer or chancre.
2. Mnemonics
Mnemonic Title: Male Infertility Levels
PRE–TEST–POST
Meaning: PRE = pre-testicular causes; TEST = testicular causes; POST = post-testicular causes.
Mnemonic Title: Semen Analysis Essentials
CoMoMo
Meaning: Co = concentration, Mo = motility, Mo = morphology.
Mnemonic Title: Genital Lesion First Look
PUW
Meaning: P = painful lesion, U = ulcer pattern, W = wart-like growth; define the morphology before choosing tests or treatment.
3. Memory Tables
Hypospadias — Anatomical Severity
| Type | Meatal Position | Clinical Significance |
|---|---|---|
| Distal | Near glans/distal penis | Generally less severe |
| Mid-penile | Penile shaft | Intermediate severity |
| Proximal | Proximal shaft/penoscrotal region | Greater functional significance; chordee may be prominent |
Common Genital Lesion Patterns
| Pattern | Typical Clue | Likely Association |
|---|---|---|
| Painless ulcer | Solitary painless chancre | Primary syphilis |
| Painful vesicles/ulcers | Grouped painful vesicles with recurrence | Genital herpes |
| Verrucous growth | Painless wart-like lesion | Genital warts |
| Discharge syndrome | Urethral discharge with dysuria | Gonococcal/chlamydial urethritis pattern |
4. Rapid Revision Points — Last-Minute Revision
- Hypospadias is defined by an ectopic urethral opening on the ventral penis.
- The more proximal the meatus, the greater the usual anatomical and functional severity.
- Chordee means ventral penile curvature and is important when planning repair.
- Avoid circumcision before specialist review because preputial tissue may be needed for reconstruction.
- Important complications after repair include urethrocutaneous fistula and meatal/urethral narrowing.
- Male infertility is approached as pre-testicular, testicular or post-testicular disease.
- Semen analysis assesses concentration, motility and morphology and directs further investigation.
- Azoospermia means no sperm in the ejaculate; oligozoospermia means reduced sperm concentration.
- Genital lesions should be described by morphology, pain and associated symptoms before treatment.
- STI management includes cause-directed treatment plus measures to reduce reinfection and transmission.
KMU Trap: A “genital lesion” is a presentation, not a diagnosis. First distinguish ulcer, vesicle or wart pattern, then select the appropriate diagnostic pathway.
5. Clinical Memory Hooks
Ventral urethral opening with downward penile curvature → hypospadias with chordee.
Thin urinary stream after hypospadias repair → consider meatal or urethral narrowing.
Infertility with abnormal sperm number, movement or shape → interpret semen concentration, motility and morphology.
Recurrent painful grouped genital vesicles → genital herpes pattern with latent viral persistence.
Urethral discharge plus dysuria after sexual exposure → urethritis pattern requiring focused STI assessment.
6. Starred High-Yield Exam Points
- ⭐ Proximal hypospadias is generally associated with greater functional significance and may have marked chordee.
- ⭐ Do not circumcise a child with hypospadias before specialist assessment because foreskin may be required for repair.
- ⭐ Urethrocutaneous fistula and meatal/urethral narrowing are important complications after hypospadias repair.
- ⭐ Semen analysis is the key initial laboratory assessment of male infertility.
- ⭐ Azoospermia requires thinking about failure of sperm production versus obstruction of sperm transport.
- ⭐ A painless genital ulcer suggests primary syphilis, whereas recurrent painful grouped vesicles suggest genital herpes.
- ⭐ Effective STI care combines appropriate treatment with counselling and appropriate partner management to reduce reinfection and transmission.
