This study in Saudi female patients with hyperprolactinemia found that pituitary imaging is often indicated due to a high prevalence of pituitary anomalies, with prolactin levels showing moderate accuracy in predicting adenomas and a suggested cutoff level of >38.71 ng/mL for diagnosis.

This case report describes a 45-year-old man with a pituitary macroadenoma whose symptoms and tumor size improved significantly after one month of treatment with cabergoline.

In this study, researchers found that the SLICK1 allele in cattle may alter local immune regulation, hair growth, and tissue remodeling, as indicated by differential gene expression pathways associated with immune and inflammatory responses in slick vs. nonslick Holsteins.

This study found higher serum prolactin levels in patients with psoriasis, vitiligo, and alopecia areata compared to controls, and prolactin levels correlated with disease severity in psoriasis and alopecia areata but not vitiligo.

This study investigated the impact of prolactin and melatonin on secondary hair follicle growth patterns in Angora and Cashmere goats using in vitro methods, without reporting new definitive results.

This study observed that beef cattle with certain prolactin receptor gene mutations, known as slick mutations, demonstrated improved post-weaning growth and temperature regulation in a hot, humid climate compared to other genotypes, suggesting genotype influences growth efficiency and heat tolerance.

ABS-201 may effectively promote hair growth in men by targeting the prolactin receptor.

This study found that adequate vitamin D status is necessary for metformin to effectively reduce prolactin levels in men with iatrogenic hyperprolactinemia, while improvements in glycemic control were observed across all vitamin D groups.

This study found that in males with alopecia areata, adult patients had significantly higher levels of adrenaline and prolactin compared to healthy controls, suggesting these hormones may play roles in the condition's development.

This study found that inhibiting prolactin secretion during the telogen phase can reduce the number of activated secondary hair follicles and the width of hair bulbs.

This study observed that women with hair loss had significantly higher serum prolactin levels compared to healthy controls. Additionally, a positive correlation between prolactin and vitamin D levels was reported, indicating potential roles for these factors in women's hair loss.

This case report describes a unique instance where elevated prolactin levels from a pituitary adenoma were associated with hirsutism due to increased dihydrotestosterone, with treatment leading to normalization.

This study found that metformin's effect on reducing prolactin levels is less pronounced in women with PCOS compared to control subjects, likely due to higher endogenous testosterone levels, despite improvements in insulin sensitivity in both groups after six months of treatment.

This review discusses the current understanding of prolactin's role in female reproductive health and the diagnosis and treatment of hyperprolactinaemia but reports no new clinical findings.

In this study, treating prolactinoma with cabergoline normalized prolactin levels and affected some androgen-related parameters, but did not significantly improve hirsutism in affected women.

This study found that women with hair loss had significantly higher free testosterone levels compared to those without hair loss.

This study found that allopregnanolone has a bimodal effect on prolactin secretion in sheep, stimulating PRL mRNA expression but inhibiting hormone release under stress and pregnancy conditions.

This study found that melatonin implants advanced the timing of the spring moult and increased hair follicle activity in adult cashmere goats, but had no significant effects on juvenile goats.

In this study, metformin was found to reduce prolactin levels in men with hyperprolactinemia and normal hair growth but not in those with androgenic alopecia, suggesting that androgen excess may interfere with metformin's effects on prolactin.

This study found that serum prolactin levels were significantly higher in patients with psoriasis, alopecia areata, and vitiligo compared to healthy controls, and prolactin levels were also correlated with disease severity in psoriasis and alopecia areata patients.

This study found that female patients with telogen effluvium had significantly lower serum prolactin levels compared to healthy controls, which contrasts with previous findings linking higher prolactin to hair loss.

This study found that while serum prolactin levels were higher in women with hirsutism, the relationship between prolactin levels and hirsutism severity was not statistically significant.

This study found no significant difference in serum prolactin levels between vitiligo patients and healthy controls, nor any significant association between prolactin gene polymorphism and vitiligo severity, except for a significant relation with BMI.

This study found that prolactin gene polymorphism in Changthangi goats showed no significant association with Cashmere quality traits, indicating the need for further research with larger sample sizes.

This case report suggests that a proactive physical therapy model can be effective for improving physical function and meeting exercise guidelines in patients newly diagnosed with systemic lupus erythematosus.

This review discusses the neurobiology of sexual function and reports no new results; the authors cover multiple endocrine and neurotransmitter influences on sexual desire, arousal, and orgasm stages.

This review discusses the etio-pathogenetic factors in benign prostatic hyperplasia and their role in the development of lower urinary tract symptoms but reports no new research findings.

Amenorrhea is relatively rare and initial testing should check FSH, TSH, and prolactin levels.

The researchers reported that in mice, prolactin signaling in the skin epithelium inhibits hair follicle stem cell activation, promoting quiescence during periods of high serum prolactin like pregnancy and lactation.
