Comparative Effects of Finasteride and Minoxidil on Male Reproductive Organs: A Systematic Review of In Vitro and In Vivo Evidence

This study found that resveratrol significantly alleviated testicular damage in male rats caused by finasteride, which otherwise led to decreased testosterone levels and various histopathological alterations in the testes.

This study found that Origanum vulgare extract improved testicular structure and function in mice against finasteride-induced damage by enhancing antioxidant defense and modulating gene expression related to apoptosis.

In this systematic review, oral minoxidil was found to be a safe and effective treatment for androgenetic alopecia and alopecia areata, with additional benefits for female pattern hair loss and other types of alopecia, although common side effects included hypertrichosis and postural hypotension.

This review discusses post-finasteride syndrome, characterized by persistent symptoms despite discontinuation, and concludes that its existence cannot be confirmed; individualized assessment is advisable for those with a history of depression, sexual dysfunction, or infertility.

This study found that AiQingHua oil improved microcirculation and promoted hair regeneration in mice with testosterone-induced alopecia.

This review discusses the evidence for post-finasteride syndrome as a condition potentially induced by finasteride and dutasteride, associating them with sexual dysfunction, depression, anxiety, and suicidal ideation in a subset of men, and reports no new clinical results.

This study reported that once-daily treatment with oral minoxidil and spironolactone for 12 months reduced hair loss severity and hair shedding in women with pattern hair loss, with generally mild side effects, though results came from an uncontrolled, observational pilot study.

The study found that finasteride increased endoplasmic reticulum stress and reduced fertility in rats, effects that were alleviated by the administration of DA-9401.

This study found that finasteride was associated with more reproductive adverse effects, including sexual dysfunction in men and fetal harm in women, compared to minoxidil in reported alopecia cases.

This article reviews the coordination of the hypothalamic-pituitary-gonadal axis, male fertility, and therapies for hypogonadism, but reports no new clinical findings.

In this laboratory study with rats, treatment with finasteride reduced dihydrotestosterone levels and fertility parameters, with a 30-day recovery period proving insufficient to fully restore sperm function and fertility.

In this study, oral finasteride treatment for four weeks reduced the weight of the corpus cavernosum in rats but did not significantly affect erectile function.

In this study using rats, finasteride-induced DHT deficiency led to morphological changes in seminiferous tubules, linked with altered junctional protein expression, potentially impairing fertility.

This review discusses the development and trials of finasteride for prostate cancer prevention, reporting reduced cancer prevalence but noting concerns about increased high-grade cancer incidence.

This study concluded that finasteride-induced DHT deficiency intensified constitutive iNOS expression in rat testicular and epididymal cells, suggesting a complex regulatory relationship needing further investigation.

In this study, treatment with finasteride altered the expression patterns of antioxidant enzymes in the epididymis of rats, potentially affecting its protective function for spermatozoa.

This review discusses the role of androgens in hair follicle regulation and suggests that a better understanding could enhance treatments for conditions like hirsutism and alopecia, but does not present new findings.

This study found that finasteride administration in hamsters led to significant spermatogenesis reduction and seminiferous tubule atrophy compared to the control group.

This review explores finasteride's effects on neuroactive steroid levels and their potential influence on disorders like depression and alcohol withdrawal but reports no new clinical findings.

Minoxidil effectively treats severe hypertension, but watch for side effects.

This study found that finasteride improves scalp hair growth in men with male pattern hair loss by reducing scalp dihydrotestosterone levels, but it did not benefit postmenopausal women with female pattern hair loss.

This study found that chronic exposure to finasteride did not significantly impact spermatogenesis in rats.

Clinical studies reported that finasteride reduces scalp dihydrotestosterone levels and improves hair growth in men with androgenetic alopecia, supporting its role as a treatment option.

This study found that minoxidil increased 17ß-hydroxysteroid dehydrogenase activity by nearly 40% in dermal papilla cells from balding scalps but not in nonbalding scalp cells or dermal fibroblasts.

Finasteride affects prostate weights and pituitary activity differently with age.

High doses of finasteride cause cell growth and tumors in mice.

In this study, researchers found that finasteride inhibits progesterone synthesis by blocking cholesterol side-chain cleavage in mouse-derived MA-10 Leydig cells, but this effect may not be evident in human or rat cells.

Finasteride treats enlarged prostate, shrinks it, improves urination, but may cause sexual dysfunction and isn't for women or children.

The study observed that finasteride reduced fertility in male Sprague-Dawley rats by impairing the formation of copulatory plugs, an effect considered specific to rats and not applicable to species without this reproductive feature.

Finasteride temporarily lowers male rat fertility without affecting libido.

In this study, topical minoxidil did not show an antiandrogenic effect on androgen-dependent cutaneous structures in the golden Syrian hamster, suggesting it likely does not have this role in humans either.

These drugs cause hair growth without affecting testosterone or adrenal hormones.

Minoxidil controls blood pressure effectively, but may cause side effects like hypertrichosis.
