Dietary L‐Tyrosine Sustains Egg Production and Quality by Modulating Promoter CpG Methylation, Gene Expression, and Hormone Profiles in Reproductive Signalling Pathways of Aged Laying Hens

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Managing prolactin (PRL)‐mediated reproductive suppression is critical for maintaining egg production in commercial laying hens. L‐tyrosine (TYR), a precursor of dopamine (DA), may counteract age‐related reproductive decline by suppressing PRL, thereby sustaining productivity and egg quality in late‐phase laying hens.

Olanzapine-Induced Hyperprolactinemia: Two Case Reports

Frontiers in Pharmacology, 2019
Background: Hyperprolactinemia is a common consequence of treatment with antipsychotics. It is usually defined by a sustained prolactin level above the laboratory upper level of normal in conditions other than that where physiologic hyperprolactinemia is

Anti‐Müllerian Hormone and Metabolic–Hormonal Profiles in Women With and Without Polycystic Ovary Syndrome: A Population‐Based Study

Endocrinology, Diabetes &Metabolism, Volume 9, Issue 5, September 2026.
In this population‐based study of 883 women, AMH declined less with age in women with PCOS than in healthy women. Higher AMH may protect older healthy women from T2DM but indicates elevated metabolic risk in younger women with PCOS, supporting its role as a life‐course biomarker for metabolic risk stratification.

Prolactin and Triiodothyronine Modulate Seasonal Variation in Brown Adipose Tissue in Djungarian Hamsters

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 345, Issue 7, Page 710-718, August 2026.
ABSTRACT Seasonal photoperiodic cycles regulate energy rheostasis in many animals. Brown adipose tissue (BAT) and the liver are key metabolic organs that show remarkable plasticity in response to photoperiodic conditions. Prolactin (PRL) and thyroid hormones are endocrine signals that transmit neural‐derived photoperiodic time measurement encoding to ...

ERKEK İNFERTİLİTESİNDE HİPERPROLAKTİNEMİNİN SEMEN PARAMETRELERİ ÜZERİNE ETKİSİ

Cerrahpaşa Medical Journal, 2019
Background and Design.­ The effect of prolactin (PRL) on spermatogenesis and semen parameters is not known well. To determine the relation between hyperprolactinemia and spermatogenesis we evaluated 85 infertile patients with hyperprolactinemia.

Prolactin in high‐metabolic risk pregnancies: Associations with maternal obesity and metabolic health

Acta Obstetricia et Gynecologica Scandinavica, Volume 105, Issue 8, Page 1490-1501, August 2026.
Higher maternal BMI before and during early pregnancy is associated with lower prolactin levels across gestation and a reduced prolactin rise. Prolactin in pregnancy may reflect maternal metabolic health and has potential relevance to lactation outcomes.

Lithium Dispensing Patterns in Dutch Youth: Prevalence, Incidence Dosages, and Duration of Use From 2011 to 2022

Bipolar Disorders, Volume 28, Issue 5, August 2026.
ABSTRACT Objective Bipolar disorder (BD) often emerges during mid‐adolescence and young adulthood, and leads to functional and social impairment, with a prevalence of 0.87% among Dutch youth. Lithium, the first‐line BD maintenance treatment, stabilizes mood, prevents suicide, and is well tolerated, yet its use has declined as long‐term second ...

Mineral metabolism and reproductive dysfunction in hyperprolactinemia

Клинический разбор в общей медицине
Hyperprolactinemia, a condition characterized by elevated prolactin levels, is associated with various organic and functional factors, including pituitary adenomas, stress, hypothyroidism, and polycystic ovary syndrome (PCOS). This study investigates the

Short‐Term Combined Treatment With Tirzepatide and Metformin for Overweight/Obese Chinese Women With Polycystic Ovary Syndrome: A Prospective, Open‐Label, Randomised Controlled Trial

Diabetes, Obesity and Metabolism, Volume 28, Issue 8, Page 7380-7392, August 2026.
ABSTRACT Aims This study aimed to assess the effects of low‐dose tirzepatide combined with metformin (COM) versus metformin (MET) monotherapy in overweight/obese women with polycystic ovary syndrome (PCOS). Materials and Methods Sixty overweight/obese women with PCOS were randomised to the MET group (1000 mg twice daily [BID]) or the COM group (MET ...
