The theory that oestriol and oestradiol have specific patterns of effect on the lower and upper reproductive tracts was investigated in the spayed rat. At dose levels which produced similar increases in uterine wet weight, there was no difference in decrease in tensile strength of the cervix. From a review of the literature, it is suggested that oestriol may exert a pronounced effect on the cervix in late pregnancy, but not because of any specific `polar' effect.
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.
