Evidence for the presence and functioning of the spinal generator for ejaculation in the neonatal male rat.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
A spinal pattern generator controls ejaculation in the male rat. In the present study, the hypothesis that the spinal generator for ejaculation was functional at early postnatal stages was evaluated. To this purpose, the expression of the ejaculatory motor pattern and its pharmacological activation in spinally transected neonatal rats from postnatal day 2 to weaning were investigated. Results revealed the presence of the rhythmic ejaculatory motor pattern in neonatal male rats. As in adult sexually experienced animals, the neonatal ejaculatory motor pattern could be elicited after the application of an ejaculation-like-releasing stimulus. The rhythmic genital motor response of neonates exhibited a gradual maturation that was reflected in its motor parameters until showing the features of the adult response at postnatal day 28. Besides, the ejaculatory motor pattern could be induced by the systemic injection of oxytocin in 7-day-old neonates as well as in adult animals. Present findings provide evidence for the presence of the spinal generator for ejaculation early during postnatal development, suggesting that its organisation is innate.
