Summary. Oxytocin, at concentrations of 4 and 40 mi.u./ml, significantly enhanced progesterone production by dispersed bovine luteal cells (0·5–4 months of gestation) after incubation for 3 h. The luteotrophic effect of 4 mi.u. oxytocin/ml was comparable to that of 10 i.u. hCG/ml. Higher oxytocin concentration (800 mi.u./ml) markedly inhibited the response of the luteal cells to hCG and may be inhibitory to basal progesterone production. These data provide evidence for an effect of oxytocin on the bovine corpus luteum of early pregnancy.

Reproduction is committed to supporting researchers in demonstrating the impact of their articles published in the journal.

The two types of article metrics we measure are (i) more traditional full-text views and pdf downloads, and (ii) Altmetric data, which shows the wider impact of articles in a range of non-traditional sources, such as social media.
