Andrology, EarlyView.Abstract Background The oxytocin receptor (OR) is a G‐protein‐coupled receptor recently identified in human spermatozoa, whose origin and role in sperm physiology remain unknown. Objectives In this study, using the pig as a model, we examine the presence of the OR in ejaculated spermatozoa through immunofluorescence and immunoblotting, and investigate ...

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

Andrology, 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

Laypeople's Views on the Narrative Identity and Societal Treatment of Genetically Modified People
Bioethics, EarlyView.ABSTRACT Genome editing in human embryos could raise new ethical issues by changing future people's narrative and numerical identity. Most philosophers agree that some genetic modifications would have larger effects on identity than others, but they disagree on what criteria might explain these differences and have not supported their claims ...

A century of theories of balancing selection
Biological Reviews, EarlyView.ABSTRACT Traits that affect organismal fitness are often highly genetically variable. This genetic variation is vital for populations to adapt to their environments, but it is also surprising given that nature – after all – ‘selects’ the best genotypes at the expense of those that fall short.

Rapid Gamete Maturation and Social Modulation Shape Reproductive Dynamics in a Brood Parasitic Catfish [PDF]
Ecol EvolObligatory brood parasitism in the Lake Tanganyika cuckoo catfish requires rapid reproductive readiness to exploit unpredictable host spawning. Our experiments showed that males are almost continuously ready to reproduce, while females ovulate about once a week, with social interactions enhancing gamete maturation in both sexes.
