Mechanism of liquefaction of the human ejaculate I. Changes of the ejaculate proteins [PDF]

Reproduction, 1979
Summary. The spontaneous liquefaction of the human ejaculate in vitro was studied by macroscopic inspection, disc electrophoresis of the ejaculate proteins, free amino acid and nitrogen determinations and by electron microscopy. Liquefaction occurred in three phases. Phase 1 was characterized by the macroscopic solubilization of the gelatinous material

BGIG10116_34868: A Newly Discovered Gene Regulating Ejaculation Function

Frontiers in Physiology, 2022
Ejaculation is a complex biphasic process involving a series of neurophysiological activities, such as the contraction of a large number of muscle groups and the ejaculation of semen from the urethra anterior.

Male reproductive system in stenopodidean shrimps: Unveiling basal reproductive traits in shrimp‐like Pleocyemata (Stenopodidae and Spongicolidae)

The Anatomical Record, EarlyView.
Abstract Stenopodidea represents one of the basal lineages within Pleocyemata, yet the male reproductive system (MRS) of this group remains poorly understood, with limited information available regarding its morphology and function. This study provides the first detailed description of the MRS in four stenopodidean shrimp species from two families ...

Premature ejaculation: is there an efficient therapy? [PDF]

Einstein (São Paulo), 2011
Premature ejaculation is the most frequent male sexual dysfunction, estimated to affect 20 to 30% of men at some time in their life. A Pubmed search from the year 2000 to the present was performed to retrieve publications related to management or ...

Evidence for adaptive explanations of semelparity in animals

Biological Reviews, EarlyView.
ABSTRACT Semelparity, the reproductive strategy of reproducing once, is widespread but uncommon in animals. Classes of models to explain the evolution of semelparity are based either on age structure and mortality schedules – demographic models in which high post‐reproductive mortality risk favours high reproductive effort and semelparity results from ...

Evaluation of Premature Ejaculation

The Journal of Sexual Medicine, 2011
ABSTRACT Introduction Premature ejaculation (PE) is a prevalent, yet often underdiagnosed, sexual disorder that affects men of all ages. Identification of PE is hampered by stigma and embarrassment associated with the condition, and limited awareness that it is treatable.

What Are We Learning About the Research‐Practice Gap From HRD Scholars and HRD Scholar‐Practitioners?

Human Resource Development Quarterly, EarlyView.
ABSTRACT The research‐practice gap (the gap) in HRD remains a significant challenge, hindering the application of academic research to practice and the integration of workplace challenges into research efforts. It is critical for HRD research to address the gap to develop evidence‐based solutions for learning and organizational performance. The purpose

Brain activation during human male ejaculation revisited

, 2007
In a prior [O-15]-H2O positron emission tomographic study we reported brain regions involved in human male ejaculation. Here, we used another, more recently acquired data set to evaluate the methodological approach of this previous study, and discovered ...
