Increase in oxytocin secretion at ejaculation in male
Abstract
In this study changes in plasma oxytocin levels were determined before and after ejaculation in patients with abnormal spermatogenesis. Plasma oxytocin levels rose significantly after ejaculation (P < 0.001, n = 17). There was no obvious correlation between plasma oxytocin levels and sperm count, sperm motility or the number of abnormal forms. Oxytocin may play a role in the precipitation of ejaculation in males.

Mating-induced effects, specifically vaginocervical stimulation in rodents and sheep, and orgasm in men and women, increase plasma oxytocin levels, whilst vaginocervical stimulation in prairie voles increases oxytocin levels in the brain.
“Mating-induced effects, specifically vaginocervical stimulation in rodents (Sansone et al., 2002) and sheep (Kendrick et al., 1986), and orgasm in men and women (Ogawa et al., 1980; Carmichael et al., 1987) increase plasma oxytocin levels, whilst vaginocervical stimulation in prairie voles increases oxytocin levels in the brain (Ross et al., 2009a,b).”

In independent studies in rodents and sheep, contexts or behaviors shown to have central oxytocin involvement also show positive increases in plasma oxytocin levels.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
