**1. Sexual Function Assessment in Brain‑Tumor Patients**
| Domain | What to Evaluate | Why It Matters | |--------|------------------|---------------| | **Physical Functioning** | • Erectile function (ED), ejaculatory issues, vaginal lubrication • Hormonal status: testosterone, estradiol, LH/FSH, prolactin | Tumors or treatment can disrupt neuro‑endocrine pathways → impotence, anorgasmia | | **Psychological / Cognitive Impact** | • Mood (depression/anxiety), self‑esteem, body image • Cognitive deficits: memory, attention, executive function | Neurocognitive decline affects sexual desire and performance; mood disorders further impair libido | | **Relationship Dynamics** | • Partner communication, intimacy expectations, relational satisfaction | Relationship strain can exacerbate sexual dysfunction or conversely be a source of support | | **Treatment‑Related Factors** | • Surgical side‑effects (nerve damage), radiotherapy-induced fibrosis, chemotherapy neurotoxicity • Hormonal therapies altering testosterone/estrogen levels | Physical changes directly influence sexual function; endocrine shifts alter libido and erectile capacity |

## Practical Clinical Recommendations
| Step | Action | Key Points | |------|--------|------------| | 1 | **Initial Screening** | • Use brief questionnaires (e.g., PHQ‑2 for depression, IIEF‑5 for erectile dysfunction) at each visit. • Ask about sexual activity and satisfaction in a non‑judgmental way. | | 2 | **Detailed History** | • Document frequency, type of intercourse, use of lubricants/condoms, pain or dyspareunia, urinary symptoms, medication side‑effects. | | 3 | **Physical & Laboratory Review** | • Assess prostate size (digital rectal exam), PSA trends. • Check testosterone, LH/FSH if erectile dysfunction is persistent despite therapy. | | 4 | **Address Modifiable Factors** | • Encourage weight loss, exercise, smoking cessation. • Discuss sexual positioning to reduce pain for the woman. | | 5 | **Therapeutic Interventions** | - **Vaginal lubricants/creams**: non‑ionic, preservative‑free options. - **Topical estrogen (for post‑menopausal)**: short course if symptomatic. - **PDE‑5 inhibitors**: titrate dose; start low to assess tolerance. - **Pelvic floor physical therapy**: can improve arousal and reduce pain. | | 6 | **Follow‑Up Plan** | - Reassess after 4–6 weeks of PDE‑5 inhibitor use and lubricant regimen. - If adequate response, maintain current dosing; if insufficient, consider dose escalation or alternative agents (e.g., vardenafil). - If still inadequate, evaluate for underlying endocrine disorders or psychological factors. |

## 3. Evaluation & Management of Low Testosterone in the Context of Hirsutism
| Step | Action | Rationale | |------|--------|-----------| | **Baseline labs** | • Serum total testosterone (morning 7–10 am) • SHBG, albumin • LH, FSH • Estradiol • Prostate‑specific antigen (PSA) if >50 yr or risk factors | Confirm androgen excess, rule out secondary causes. | | **Interpretation** | • Low testosterone with normal/low SHBG suggests primary hypogonadism • Elevated LH indicates primary testicular failure • Normal LH/FSH may indicate secondary hypogonadism (pituitary/hypothalamic) | Tailor therapy accordingly. | | **Baseline labs before therapy** | • CBC, CMP, lipid panel, fasting glucose, HbA1c, testosterone (morning), PSA (if >50 yr) | Establish baseline for monitoring. |

## 4. Treatment Algorithm
### Step‑by‑Step Decision Tree
``` START | |---> Check eligibility: • No contraindications (no severe liver disease, untreated hypertension, etc.) • Informed consent obtained. | |---> Baseline labs: • CBC, CMP, fasting lipids, fasting glucose/HbA1c, testosterone (morning), PSA (if >50). | |---> Select anabolic agent: |--- Option A: Enobosarm (oral) – 2.5–10 mg daily |--- Option B: SARMs via injection (e.g., Ostarine 25 mg IM weekly) | |---> Determine dosing schedule based on product availability and patient's preference. | |---> Initiate therapy: |--- Educate patient on potential side effects: • Mild liver enzyme elevations • Transient lipid changes (increase LDL, decrease HDL) • Mood alterations • Possible gynecomastia (rare) | |---> Monitoring plan: |--- Baseline labs: LFTs, fasting lipids, CBC, testosterone levels. |--- Repeat labs at 4–6 weeks post-initiation, then every 3 months. |--- Adjust dose or discontinue if AST/ALT > 2× ULN or lipid abnormalities exceed thresholds. | |---> Duration: |--- Use for the shortest effective period (e.g., 12–24 weeks). |--- After completion, reassess motivation and consider alternative interventions. | |---> Safety considerations: |--- Avoid use in individuals with uncontrolled hypertension, active liver disease, or those on medications metabolized by CYP3A4 that could interact with ketone metabolism. |--- Monitor for signs of ketoacidosis (e.g., nausea, vomiting, abdominal pain). | END ```
**Key Points:**
- **Ketone supplements may alter brain fuel availability and influence motivation.** - **Safety hinges on monitoring metabolic status and avoiding high‑dose or prolonged use.** - **A structured protocol can help balance potential benefits against risks for those seeking to enhance task engagement.**
This approach offers a systematic way to evaluate whether ketone supplementation could be a viable tool for improving sustained effort in demanding cognitive tasks, while ensuring participant safety.
