Brown colour in Semen is seen

Correct Answer: B

Rationale: Brown semen (hematospermia) in spinal cord injury reflects blood from neurogenic dysfunction or catheterization common association. Infection typically causes pus/yellow, not brown different etiology. Medications (e.g., rifampin) alter urine, not semen color unrelated. Sexual activity may cause transient blood, but not specific less likely. Spinal injury's link distinguishes it, key to neurogenic hematospermia, unlike infection, drug, or activity causes.

Correct Answer: B

Rationale: Persistent basketing despite ureteral tear causes avulsion force detaches ureter, complicating injury. No dilation risks trauma but not avulsion less severe. Holmium laser fragments stones, not primary avulsion cause tool-based. Non-dilated system increases resistance, not detachment predisposing. Persistence with tear distinguishes it, critical for this iatrogenic risk, unlike preparatory or tool-related factors.

Correct Answer: B

Rationale: Pelvic floor muscle training (PFMT) treats stress, urge, and mixed incontinence in both genders, all ages strengthens support (stress) and reflex inhibition (urge). Gender restriction is false men benefit (e.g., post-prostatectomy). Age doesn't limit efficacy older adults respond. Urge exclusion is wrong PFMT aids detrusor control. Broad efficacy distinguishes it, key to non-invasive therapy, unlike restrictive claims.

Correct Answer: B

Rationale: Hereditary nonpolyposis colorectal cancer (HNPCC/Lynch) strongly links to GU cancers (e.g., ureter, bladder) mismatch repair defects. FAP ties to colon, not GU adenomas. Li-Fraumeni (p53) hits soft tissue, not GU-specific. MEN I (pituitary, pancreas) lacks GU focus endocrine. HNPCC's GU association distinguishes it, critical for urologic tumor risk, unlike colon, broad, or endocrine syndromes.

Correct Answer: A

Rationale: Black race has lower testicular cancer risk whites predominate, not a factor. Cryptorchidism (undescended testis) increases risk malpositioned germ cells. Family history raises odds genetic link. Germ cell neoplasia in situ is precursor direct cause. Lower black risk distinguishes it, key to epidemiology, unlike established high-risk factors.
