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, finasteride treatment for 56 days in adult rats led to sloughing of immature germinal cells and reduced sperm content in the epididymis, indicating its importance for maintaining spermatogenesis.

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 study established a stable rabbit model of hypospadias using finasteride, finding varied rates of the condition's severity and associated testicular retention across different gestation day treatments.

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.

The authors reported that young men with infertility-related conditions experienced improved seminal quality after stopping finasteride, suggesting potential adverse effects on fertility during treatment.

This case report suggests that increased dietary calcium from alfalfa may have contributed to zinc deficiency in two adult female goats by blocking zinc absorption.

This systematic review found that PCOS is a leading cause of anovulatory infertility, accounting for 70% of such cases, and emphasized the importance of using ultrasound for diagnosis.

This study found that adding zinc to the drinking water improved hair coat and skin condition in moustached marmosets with symptoms resembling zinc deficiency.

In this study, pregnant spotted hyenas treated with flutamide and finasteride had lower concentrations of several sex hormones, including testosterone and luteinizing hormone, compared to untreated controls.

This case report describes two German shepherd dogs with prostatitis that showed favorable responses to treatment with finasteride, phenazopyridine, and enrofloxacin.

This abstract discusses the effects of finasteride on semen and hormone parameters in men with infertility but does not provide new research findings.

This study reviewed the literature on cryptorchidism in dogs and found it may be associated with dermatological issues like alopecia, with surgical intervention and cyclosporine offering partial benefit.

In this systematic review, researchers observed that Toxoplasma gondii infection is associated with alterations in testosterone levels, generally increasing in humans but showing mixed effects in animals, highlighting a complex relationship that warrants further investigation.

This report emphasizes the importance of considering haemochromatosis and conducting iron studies when investigating infertility due to endocrine causes.

Among Australian fur seals at one colony, this study found that alopecia, primarily affecting juvenile females, is linked to hair shaft fractures associated with low tyrosine and zinc levels, as well as higher pollutant exposure.

This study reported intra-familial transmission of Arthroderma benhamiae among Canadian porcupines in a Japanese zoo, with genetic sequences previously undocumented in Japan or the GenBank database.

This article reviews the impact of aging and related urologic conditions on male fertility, highlighting the effects of various treatments on sperm parameters and recommending pre-treatment counseling for fertility preservation. It reports no new clinical results.

This study explored the effects of MOTILIPERM on infertility in a rat model with varicocele and oxidative stress, reporting its potential therapeutic efficacy.

This study found that administering testosterone to pregnant rats altered connexin 26 and connexin 43 expression in the uterus, which could disrupt embryo implantation and cause early pregnancy loss.

This study observed that numerical chromosomal aberrations were more common in men with severe male factor infertility and azoospermia compared to those with other sperm quality issues, while chromosomal translocations were significantly associated with oligoasthenozoospermia, highlighting important genetic counseling considerations.

In this study, exposure to the drug finasteride in Silurana tropicalis significantly increased testosterone levels in liver and testis tissues and altered gene expression related to male reproduction and oxidative stress.
