Benign Prostatic Hyperplasia Treatment Options and Their Effects on Sexual Function

Sexual experiences of cancer survivors: A qualitative study in Jordan

Background

In Jordan, cancer is the second leading cause of death after cardiac disease. The impact of cancer on sexual relationships is a taboo subject and hence, such issues are underreported research among Jordanian people examining unmet needs.

Aim

To examine the experiences and preferences of Jordanian cancer survivors related to communication regarding their sexual needs.

Methods

Qualitative study conducted between May and June 2020 using semi-structured face-to-face interviews using the snow-balling approach for recruitment. Participants were recruited until data saturation was obtained and data were analyzed using qualitative thematic analysis.

Results

Analysis of participants’ interview data identified three main categories: 1) The psychological impact of cancer of sexual relationships; 2) Physician support; 3) Variations in sexual life and sexual experiences.

Conclusion

The study revealed that there is a substantial psychological impact of cancer on sexual relationships among Arab Jordanian cancer survivors. Feeling powerless, being labelled as ‘sexually disabled’, and lack of communication with physicians were emphasized by participants as a barrier to discuss sexual needs with their physicians. Lack of physicians support negatively impact Jordanian cancer survivors sexual experience and led to increased their sense of powerlessness and loss of control over sexual relationships.

Implications for practice

Overall, the study indicated a crucial need for physicians to encourage patients to disclose their sexual experience to help them maintain their sexual and mental health while in the fight against cancer. The physicians, nurses and allied health professionals should be engaged in the conversation with patients by taking an active role in the discussion. Additionally, the family and partners of the patients should also be approached and engaged by health professionals in the discussion to address their needs or sexual issues.

Prostatic Artery Embolization and Sexual Function: Literature Review and Comparison to Other Urologic Interventions

Many interventions to treat men with benign prostatic hyperplasia (BPH) associated lower urinary tract symptoms (LUTS) are associated with sexual side effects or complications, such as hematospermia, erectile dysfunction, or ejaculatory dysfunction. As loss of sexual function can significantly impact quality of life, an optimal treatment for BPH associated LUTS would be one without any sexual dysfunction side effects. Prostatic artery embolization is a minimally invasive treatment for men with BPH associated LUTS. The aim of this paper is to review the effects of prostatic artery embolization on sexual function and compare the sexual side effect profile to the other available BPH procedures.

A double blind, placebo-controlled randomized comparative study on the efficacy of phytosterol-enriched and conventional saw palmetto oil in mitigating benign prostate hyperplasia and androgen deficiency

Background

The present clinical trial was conducted to evaluate the efficacy and tolerability of a standardized saw palmetto oil containing 3% β-sitosterol in the treatment of benign prostate hyperplasia (BPH) and androgen deficiency.

Methods

Subjects aged 40–65 years with symptomatic BPH were randomized to 12-week double-blind treatment with 500 mg doses of β-sitosterol enriched saw palmetto oil, conventional saw palmetto oil and placebo orally in the form of capsules (n = 33 in each group). BPH severity was determined using the International Prostate Symptom Score (IPSS), uroflowmetry, serum measurement of prostate specific antigen (PSA), testosterone and 5α-reductase. During the trial, the androgen deficiency was evaluated using Aging Male Symptoms (AMS) scale, the Androgen Deficiency in the Aging Male (ADAM) questionnaire, serum levels of free testosterone.

Results

Subjects treated with β-sitosterol enriched saw palmetto oil showed significant decrease in IPSS, AMS and ADAM scores along with reduced postvoiding residual volume (p < 0.001), PSA (p < 0.01) and 5α-reductase from baseline to end of 12-week treatment as compared to placebo. There was also a significant increment in the maximum and average urine flow rate (p < 0.001), and serum free testosterone level of subjects treated with enriched saw palmetto oil as compared to placebo.

Conclusion

This study demonstrates the efficacy of β-sitosterol enriched saw palmetto oil superior to conventional oil thus extending the scope of effective BPH and androgen deficiency treatment with improved quality of life through the intake of functional ingredients.

[Influence of medical BPS treatment on sexual function]

BACKGROUND

Benign prostate syndrome is frequently associated with sexual dysfunction. The therapeutic options discussed in the S2e guideline may be able to improve existing sexual dysfunctions but can also worsen disorders or even trigger new ones.

OBJECTIVES

What are the effects of therapeutic options as described in the S2e guideline on sexual function?

METHODS

By selective literature search related to benign prostate syndrome and sexual dysfunction adverse effects of drugs mentioned in the S2e guideline have been evaluated.

RESULTS

Serenoa repens extracts do not have adverse effects on sexual function; this is also true for muscarine receptor antagonists. 5α-Reductase inhibitors frequently worsen erectile function, libido and ejaculation; selective α₁-blockers have an adverse effect on ejaculation. Phosphodiesterase (PDE)-5 inhibitors can improve sexual function. A combination of α₁-blockers and 5α-reductase inhibitors worsens sexual functions significantly.

CONCLUSIONS

A suitable therapy for benign prostate syndrome should be chosen jointly by the patient and the treating physician and should be adapted to personal needs. Effects on sexual functions have to be taken into consideration when choosing a therapy.

Do 5α-Reductase Inhibitors Raise Circulating Serum Testosterone Levels? A Comprehensive Review and Meta-Analysis to Explaining Paradoxical Results

INTRODUCTION

Many studies have reported that 5α-reductase inhibitors (finasteride and dutasteride) raise serum testosterone (T) levels, yet there is lack of consistency among studies on this point.

AIM

To review and meta-analyze available studies reporting changes in serum T concentrations in men treated with 5α-reductase inhibitors (5α-RIs).

METHODS

A Medline search using PubMed and EMBASE was performed including the following key words: "finasteride," "dutasteride," "testosterone and 5α-reductases."

MAIN OUTCOME MEASURE

Relevant studies were extracted, evaluated, and analyzed. Of these, 40 studies were analyzed qualitatively and 11 were included in the meta-analysis. A random effects model was used to conduct the meta-analysis.

RESULTS

In 11 studies comprising 1,784 patients with age ranging between 18 and 83 years and average treatment follow-up of 17 months, meta-analytic estimate of the mean baseline change was 27 (95% confidence interval 1-54). The meta-analysis did not demonstrate unequivocal significant increase in serum T levels. The increase was not uniform among all studies reported. Sensitivity analysis showed that no single study contributed decisively to the outcome or could be attributed to drug action. The reported increases in T levels with finasteride or dutasteride in men with low baseline serum T may be attributed, in part, to increased trapping of T by unsaturated sex hormone binding globulin (SHBG) due to dissociation of 5α-dihydrotestosterone. In men with high baseline T levels, there appears to be no change in serum T levels. 10 studies reported luteinizing hormone, follicle-stimulating hormone, SHBG, and estradiol values and none reported significant changes in their levels, suggesting that observed changes in serum T levels are unlikely mediated by gonadotropins levels or peripheral conversion of T to estradiol.

CONCLUSION

5α-RI therapy is not associated with consistent and significant increases in serum T levels. Traish AM, Krakowsky Y, Doros G, et al.
