Changes in environmental exposures over decades may influence the genetic archi...
Cerván-Martín, Miriam; González-Muñoz, Sara; Guzmán-Jiménez, Andrea; Higueras-Serrano, Inmaculada; Castilla, José A.; Garrido, Nicolás; Luján, SaturninoStudy question: Do the genetic determinants of idiopathic severe spermatogenic failure (SPGF) differ between generations? Summary answer: Our data support that the genetic component of idiopathic SPGF is impacted by dynamic changes in environmental exposures over decades. What is known already: The idiopathic form of SPGF has a multifactorial etiology wherein an interaction between genetic, epigenetic, and envi...

Guzmán-Jiménez, Andrea; González-Muñoz, Sara; Cerván-Martín, Miriam; Rivera-Egea, Rocío; Garrido, Nicolás; Luján, Saturnino; Santos-Ribeiro, SamuelBackground: Severe spermatogenic failure (SPGF) represents one of the most relevant causes of male infertility. This pathological condition can lead to extreme abnormalities in the seminal sperm count, such as severe oligozoospermia (SO) or non-obstructive azoospermia (NOA). Most cases of SPGF have an unknown aetiology, and it is known that this idiopathic form of male infertility represents a complex condition...
Immune and spermatogenesis-related loci are involved in the development of extr...
Cerván-Martín, Miriam; Tüttelmann, Frank; Lopes, Alexandra M.; Bossini-Castillo, Lara; Rivera-Egea, Rocío; Garrido, Nicolás; Lujan, SaturninoWe conducted a genome-wide association study in a large population of infertile men due to unexplained spermatogenic failure (SPGF). More than seven million genetic variants were analysed in 1,274 SPGF cases and 1,951 unaffected controls from two independent European cohorts. Two genomic regions were associated with the most severe histological pattern of SPGF, defined by Sertoli cell-only (SCO) phenotype, name...
Evaluation of Male Fertility-Associated Loci in a European Population of Patien...
Cerván-Martín, Miriam; Bossini-Castillo, Lara; Rivera-Egea, Rocío; Garrido, Nicolás; Luján, Saturnino; Romeu, Gema; Santos-Ribeiro, SamuelInfertility is a growing concern in developed societies. Two extreme phenotypes of male infertility are non-obstructive azoospermia (NOA) and severe oligospermia (SO), which are characterized by severe spermatogenic failure (SpF). We designed a genetic association study comprising 725 Iberian infertile men as a consequence of SpF and 1058 unaffected controls to evaluate whether five single-nucleotide polymorphi...
