This study found that older age at puberty may be associated with lower semen quality and altered reproductive hormone levels in young men, though only some results were statistically significant.

This meeting abstract details various lectures and workshops from the 30th Annual Meeting of the American Society of Andrology, including findings on genetic and physiological factors affecting male fertility, but reports no new clinical results.

This collection of articles explores advancements in reproductive technologies for domestic dogs and cats, highlighting improvements like finasteride treatment for BPH in dogs and a rapid freezing method for cat sperm that enhance fertility preservation and genetic resource banking.

This review summarizes recent research on the molecular properties and functions of L-PGDS and PGD2, but reports no new findings, highlighting their pathophysiological roles and guiding future studies.

This review highlights that various targeted cancer therapies are associated with specific ocular side-effects, emphasizing the importance of awareness among ophthalmologists for timely diagnosis and management.

In this retrospective study, oral tofacitinib treatment for at least 6 months improved scalp hair loss in 69.1% of alopecia areata patients, with patchy AA cases responding better compared to other subtypes, and no significant adverse effects were reported.

In this study, topical application of a 10% minoxidil lotion on mature rats over 72 days was associated with reduced testis and epididymis mass and sperm motility, indicating potential gonadotoxic effects.

This study found that papillary dermal fibroblast progenitors in newborn mouse skin can be isolated and cultured to generate male germline cell precursors, demonstrating their potential through differentiation into cells with meiotic capability.

This review highlights that various commonly prescribed medications for chronic conditions may impact male fertility by affecting hormone secretion, sperm production, ejaculation, erectile function, and libido, although conclusive evidence is limited to specific drug groups.

In this study, oral melatonin given to male Pomeranian dogs with Alopecia X improved semen quality and testicular blood flow in a dose-dependent manner, but altered hormonal balance, indicating complex effects that require further investigation for long-term implications.

This review highlights the limited effectiveness of current unlicensed treatments for male subfertility, like hormonal therapy and antioxidants, and emphasizes new drug discovery methods such as high-throughput screening and drug repurposing to improve treatment development for male subfertility.

This article discusses the hypothalamus-pituitary-testis axis in androgen production and spermatogenesis but presents no new research findings.

In this study, researchers analyzed spermogram data from men with diagnosed infertility in Ukraine, aiming to identify the most common sperm disorders, and they found that the study primarily involved men with primary infertility, compared to a control group of healthy men with confirmed fertility.

This study found that Cutl1 mutant mice experienced retarded lung differentiation and abnormal hair follicle morphogenesis, indicating the vital role of CDP in lung development and hair follicle cell-lineage specification.

This study found that finasteride treatment in males with androgenetic alopecia was linked to significant changes in sperm parameters and increased testosterone levels, but no sexual dysfunction was observed, and sperm parameters returned to baseline after treatment stopped.

This review examines the impact of biotin, vitamin B12, and zinc on male reproduction, emphasizing their role in spermatogenic failure, but reports no new clinical results.

In this animal study, finasteride exposure led to impaired spermatogenesis in rats, while the novel compound DA-9401, derived from three medicinal herbs, demonstrated potential in improving sperm parameters and reducing testicular apoptosis when used alone or with finasteride.

This study observed that adding simvastatin to ongoing metformin treatment reduced certain androgen levels in women with non-classic congenital adrenal hyperplasia and abnormal glucose metabolism, suggesting a potential therapeutic benefit.

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.

This study found no evidence of androgen deficiency or decreased peripheral androgen action in men with persistent sexual symptoms after finasteride use, but identified links to depressed mood and abnormal brain function.

This study described four adult male cases of Kennedy disease with typical neurological symptoms and noted gynecomastia as the most frequent endocrinological manifestation, accompanied by an abnormal expansion in the androgen receptor gene.

The April 2014 issue of "Fertility and Sterility" discussed various reproductive health topics, including hormone therapy benefits, sperm and genetic factors in male infertility, and the link between PCOS and diabetes.

This study assessed contraceptive use among women in Mukalla city, Yemen, reporting that 78.7% experienced side effects such as hair loss and abnormal bleeding, with oral contraceptive pills being the most common method.

This study found that 27% of women with polycystic ovary syndrome reported perceived scalp hair thinning, which was associated with factors like advancing age, subjective hirsutism, disturbed sleep, smoking, abnormal glucose tolerance, and meal skipping.

This study suggests that abnormal levels of zinc, copper, and iron in serum or hair may serve as auxiliary and prognostic tests for various skin diseases, though further research is necessary due to conflicting data.

This review discusses the potential of nanotechnology in treating idiopathic pulmonary fibrosis by targeting abnormal alveolar epithelial cells and reports no new clinical results.

Amenorrhea, or the absence of periods, should be evaluated by age 15 or within five years of early breast development, and is most commonly caused by conditions like polycystic ovary syndrome and hypothalamic amenorrhea.

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.

The authors reviewed the mechanisms behind Kennedy's disease, noting advances in therapeutic strategies such as androgen deprivation and gene silencing that may soon expand treatment options for this incurable neuromuscular condition.

This review found that both finasteride and dutasteride are effective for treating hair loss in men with androgenetic alopecia, with dutasteride showing higher efficacy, but noted unclear clinical significance regarding potential negative impacts on reproduction, including possible sexual dysfunction and effects on spermatogenesis.
