Male Subfertility and Prostate Cancer Risk: Epidemiological and Genetic Studies
… parameters, subfertility, hypospadias, or cryptorchidism; 2) whether childlessness secondary to male subfertility is associated with reduced PCa risk; and 3) the possible involvement of genetic variants in reducing PCa risk in subfertile men, including in the sex steroid signaling pathway …

Reproductive health effects due to pesticide exposure amongst boys in the rural Western Cape, South Africa
… organ defects, cancers and declining fertility. Cryptorchidism, hypospadias, testicular cancer and poor sperm quality (testicular dysgenesis syndrome) have also been reported to be associated with these endocrine-disrupting chemicals. This study therefore aims to investigate the adverse …

Kriptorchizmo chirurginio gydymo laikas ir vaisingumo prognozė vertinant spermatogenezę sėklidžių biopsijose /
… most relevant time for surgical management of cryptorchidism. Ad spermatogonia have been chosen as a major histological factor reflecting normal testicular maturation and fertility. Efforts were put to evaluate correlation between the former criterion and the age at orchopexy to define age …

EVALUATION OF ENVIRONMENTAL FACTORS ON CANINE REPRODUCTION AND FERTILITY: INNOVATIVE STRATEGIES
… within other two studies we focused on cryptorchidism. Through the application of immunohistochemical techniques and miRNomics, we found precancerous lesions and molecular dysregulation in both retained and scrotal gonads of affected patients. Interesting implications have emerged from …

The impact of genetic, environmental and life-style factors on male reproductive function
… it was suggested that poor sperm quality, cryptorchidism, hypospadias and TC have a common cause and are symptoms of a so called Testicular Dysgenesis Syndrome (TDS). The aetiology of TDS is unknown but genetic, environmental and life-style related factors have been suggested as its causes. …

Intergenerational and Transgenerational Effects of Endocrine Insults
… between bisphenol A (BPA) level and offspring cryptorchidism, and between detection of n-propyl paraben and shorter anogenital distance (a marker of intrauterine androgen activity). Next, I investigated inter- and transgenerational effects of EDCs in mice by exposing pregnant/lactating females …

Role of androgens in testicular development and dysgenesis
… reproductive health which manifest at birth (cryptorchidism, hypospadias) or in young adulthood (testicular germ cell cancer and low sperm counts), are common and may be increasing in incidence. These disorders have a common fetal origin and share risk factors; consequently they are …

The MA-10 Cell Line as a Model of insl3 Regulation and Leydig Cell Function
<p>Leydig cells produce testosterone in response to luteinizing hormone (LH) via the cyclic adenosine monophosphate (cAMP)/protein kinase A pathway. Additionally, these cells are responsible for producing insulin-like peptide 3 (INSL3), a peptide hormone that is essential for testicular descent. …
