CRISPR/Cas9‐mediated Genome‐editing Reveals 10 Testis‐enriched Genes and One Non‐testis‐enriched Gene are Dispensable for Male Fecundity in Mice

open access: yesAndrology, EarlyView.
ABSTRACT Background More than 1000 genes have been identified as predominantly expressed in the human testis. Advances in gene editing technologies have enabled the rapid and efficient generation of genetically engineered mice. This approach facilitates the screening of genes essential for spermatogenesis by analyzing knockout mouse models.

Healthy Aging Men Do Not Suffer From Relevant Limitations of Their Reproductive Functions

open access: yesAndrology, EarlyView.
Abstract Background While metabolic disorders are well‐established contributors to testosterone decline and erectile dysfunction (ED), little is known about the natural progression of reproductive parameters in healthy aging men. Objectives This study aimed to evaluate longitudinal changes in reproductive parameters and sought to determine the ...

Sperm Telomere Interactions Are Impaired in Testicular Cancer Before and After Adjuvant Therapy

open access: yesAndrology, EarlyView.
ABSTRACT Background No study has yet explored telomere length or interaction in sperm nuclei of testicular cancer (TC) patients exposed to chemotherapy or radiotherapy. However, sperm telomere dynamics have emerged as a potential marker in male infertility.

Microtubule Inner Protein CFAP77 Contributes to Sperm Motility and Male Fertility in Mice

open access: yesAndrology, EarlyView.
ABSTRACT Background Sperm motility is essential for male fertility, and its regulation is dependent on the structural integrity of the axoneme. The axoneme consists of a conserved “9+2” microtubule arrangement and is supported by microtubule inner proteins. However, the functional significance of many microtubule inner proteins remains unclear.

Pig Seminal Plasma Extracellular Vesicles Enhance Motility During Preservation of Epididymal Spermatozoa but Impair Capacitation and IVF Parameters

open access: yesAndrology, EarlyView.
ABSTRACT Background Extracellular vesicles (EVs) produced by accessory sex glands play a key role in sperm functionality, influencing motility, viability, acrosome integrity, metabolic activity, and capacitation. Most studies on the effects of EVs on spermatozoa have focused on ejaculated spermatozoa, which have already been exposed to their own native

The Spermicide Effect from Methanol Extract of Kalangkala Seed (Litsea angulata) to Spermatozoa Mice (Mus musculus)

open access: yesJournal of Agromedicine and Medical Sciences (AMS), 2016
Men involvement in family planning needs to be increased by providing natural spermicide from natural source which is safer. One of them is kalangkala seed which is endemic plant in South Kalimantan.

Seminal Plasma Exosomal miRNA Profiling Reveals hsa‐miR‐7‐5p as a Key Regulator of Sperm Motility in Asthenozoospermia

open access: yesAndrology, EarlyView.
ABSTRACT Background Asthenozoospermia is a significant contributing factor to male infertility. Accumulating evidence indicates that impaired sperm motility is closely linked to dysregulated microRNA expression during spermatogenesis. Seminal plasma exosomes are enriched with diverse microRNAs, which play pivotal roles in modulating sperm motility, the

Cryopreservation of Spermatozoa Prior and Post‐Orchiectomy in Patients With Testicular Germ Cell Cancer—Does the Timing Matter?

open access: yesAndrology, EarlyView.
ABSTRACT Background Testicular germ cell cancer (TGCC) is the most frequent malignancy in young men of reproductive age. According to guidelines, semen cryopreservation should be performed prior to orchiectomy. Lack of time and local facilities as well as mental pressure are challenges in terms of fertility preservation before surgery.

Comprehensive Quantification of Oligoasthenozoospermia Induced by Obesity, Reproductive Toxicants, and Their Combination in Rat Models

open access: yesAndrology, EarlyView.
ABSTRACT Background Oligoasthenozoospermia is a leading cause of male infertility and has been increasingly associated with the global surge in obesity and exposure to reproductive toxicants. Despite extensive research on each factor individually, their combined pathological effects remain poorly understood.

Parental Educational Attainment at Birth and Biomarkers of Male Fecundity: A Study From the Danish National Birth Cohort

open access: yesAndrology, EarlyView.
ABSTRACT Background Low parental education is associated with poorer offspring health, but its influence on male fecundity remains unclear. Objective To study the association between parental educational attainment at birth and biomarkers of male fecundity in young men and to explore whether this association is mediated by maternal smoking in pregnancy
