March 2015 in “PloS one” This study demonstrated that an AR-EGFP transgene can restore AR function and fertility in Sertoli cell-specific AR knockout mice, highlighting its potential use in understanding androgen receptor functions.
11 citations
,
March 2010 in “International Journal of Andrology” This article reviews multiple entries on the Androlog blog regarding finasteride use, concluding that a 1-mg dose does not adversely affect spermatogenesis or pose a risk during conception or pregnancy.
1 citations
,
May 2024 in “The Journal of Sexual Medicine” This case report suggests that clomiphene citrate can effectively restore fertility in some men with a long history of anabolic steroid abuse, though individual responses to treatment vary.

January 2002 in “Yaoxue jinzhan” This study found that Epristeride and Finasteride reduced prostate development and testis weight in male rats, but only Finasteride appeared to impact reproductive function.
October 2021 in “bioRxiv (Cold Spring Harbor Laboratory)” This study found that a mild intramuscular dose of BOTOX increased spermatogenesis and improved sperm quality in ageing mice, suggesting potential benefits for managing male infertility.
June 2011 in “Portuguese National Funding Agency for Science, Research and Technology (RCAAP Project by FCT)” The researchers reported that both estrogen receptors ERα and ERβ are expressed in human testis, and identified two novel genes, Aven and Regucalcin, linked to estrogen and androgen regulation, which may be crucial for spermatogenesis.
This study found that finasteride treatment in adult hamsters led to significant testicular alterations and reduced spermatogenesis compared to untreated controls.
July 2007 in “Journal of Reproduction & Infertility” This study found that in male rats, finasteride significantly decreased spermatogonia and primary spermatocytes numbers and increased Leydig cells, but did not affect overall testis histology or spermatogenesis.
August 2020 in “DOAJ (DOAJ: Directory of Open Access Journals)” This study found that Finasteride at doses of 5 mg or higher may reduce the expression of key spermatogenesis biomarkers, potentially impacting male fertility in mice.
14 citations
,
March 2020 in “Cold Spring Harbor Perspectives in Biology” This review discusses the flexibility and diversity of tissue stem cell systems, particularly focusing on the motility and ligand distribution of spermatogenic stem cells, without presenting new experimental results.
31 citations
,
January 2001 in “PubMed” In this randomized study of male contraceptive regimens, adding finasteride did not significantly enhance spermatogenesis suppression compared to the control group.
2 citations
,
March 2017 in “Canadian Urological Association journal” This case report documents the first use of clomiphene citrate to potentially improve fertility in a man taking finasteride, highlighting sperm count issues associated with the medication.
This study found that chronic administration of dutasteride in rats did not affect spermatogenesis or oxidative stress in the testes, although it altered hormone levels.
5 citations
,
June 2008 in “Acta Cirurgica Brasileira” This study found that finasteride administration in hamsters led to significant spermatogenesis reduction and seminiferous tubule atrophy compared to the control group.
January 2013 in “Reproductive Biology” 2 citations
,
December 2001 in “PubMed” In this review, the authors found no evidence of harmful pregnancy outcomes from exposure to finasteride, and report that handling the medication poses negligible risk to a fetus.
2 citations

March 2022 in “Laboratory Animal Research” This study suggests that a mild intramuscular dose of botulinum toxin improved spermatogenesis and sperm parameters in ageing mice.
March 2024 in “Veterinary sciences” This study is the first to detail major geriatric diseases in aged Julia Creek dunnarts, particularly highlighting hormonal issues like cystic glandular hyperplasia in females and testicular degeneration in males, suggesting these conditions are linked to aging and potentially hormonal dysregulation.
This study is the first to report major spontaneous diseases in aging Julia Creek dunnarts, highlighting hormonal dysregulation and lymphoid neoplasia as common conditions in this endangered species.
This study is the first to document significant age-related pathologies in endangered captive Julia Creek dunnarts, highlighting hormonal dysregulation and reproductive issues in females, while males exhibited higher occurrences of cutaneous diseases and testicular degeneration, providing valuable insight for conservation efforts.
