Thyroid and male reproduction

Indian Journal of Endocrinology and Metabolism, 2014
Male reproduction is governed by the classical hypothalamo-hypophyseal testicular axis: Hypothalamic gonadotropin releasing hormone (GnRH), pituitary luteinizing hormone (LH) and follicle stimulating hormone (FSH) and the gonadal steroid, principally, testosterone.

Nutraceutical in male reproduction

Brazilian Journal of Veterinary Medicine, 2018
In order to obtain a successful outcome in artificial insemination programs, a few precautions must be taken with regard to male breeders. It is established that environmental factors can change the hormonal secretion, the cell differentiation that occurs in the testicles, as well as sperm maturation and transport in the epididymis.  In view of adverse

Comprehensive Analysis of circRNAs, miRNAs, and mRNAs Expression Profiles and ceRNA Networks in Decidua of Unexplained Recurrent Spontaneous Abortion

Frontiers in Genetics, 2022
The diagnosis and treatment of unexplained recurrent spontaneous abortion (URSA) are subject to debate, because the exact underlying mechanisms remain unclear. To address this issue, we elucidated the expression profiles of dysregulated circRNAs, miRNAs,

A missense variant in NCF1 is associated with susceptibility to unexplained recurrent spontaneous abortion

Open Life Sciences, 2022
Unexplained recurrent spontaneous abortion (URSA) is a major concern in reproductive medicine. Neutrophil cytosolic factor 1 (NCF1) polymorphisms leading to low production of reactive oxygen species (ROS) are strongly associated with autoimmune diseases.

Prevalence of preconception TORCH infections and its influential factors: evidence from over 2 million women with fertility desire in southern China

BMC Women's Health, 2023
Background TORCH (Toxoplasma gondii [TOX], Cytomegalovirus [CMV], Rubella virus [RV], and Herpes simplex virus [HSV]) represents pathogens known to traverse the maternal-fetal barrier and cause severe neonatal anomalies. We aimed to assess the prevalence

Effects of varicocele and microsurgical varicocelectomy on the metabolites in semen

Scientific Reports, 2022
The influence of varicocele and microsurgical varicocelectomy on semen quality remains unclear. Few studies have investigated the relationship between semen metabolism and the abnormalities in reproductive function caused by varicocele, however, there is

Serum Concentrations and Gonadal Expression of INSL3 in Eighteen Males With 45,X/46,XY Mosaicism

Frontiers in Endocrinology, 2021
ObjectiveInsulin-like factor 3 (INSL3) is produced in the testes and has been proposed as a circulating biomarker of Leydig cell capacity, but remains undescribed in 45,X/46,XY mosaicism. The aim was to examine serum concentrations and gonadal expression

Prolactin and Male Reproduction [PDF]

Archives of Andrology, 1981
Elevated levels of prolactin(PRL) are associated with gonadal dysfunction in men and women, but the relationship between PRL levels and gonadal activity is best defined in women. The purpose of this review is to summarize and discuss the influence of PRL on the male reproductive function in normaprolactinemia and to describe the clinical, diagnostic ...

Prenatal exposure to phenols and benzophenones in relation to markers of male reproductive function in adulthood

Frontiers in Endocrinology, 2022
IntroductionEnvironmental exposure during fetal life may disrupt testicular development. In humans, a limited number of studies have investigated whether these adverse effects persist into adulthood.
