Summary.

Blood serum collected from female mice treated with oestrogen and progesterone was assayed for its ability to induce acrosome degeneration. The maximum activity was found in serum obtained from females treated with 1·0 μg oestrogen/day for 5 days. Lower doses did not produce any significant difference from the control group. Blood serum from pregnant or ovariectomized females treated with progesterone did not significantly depress the incidence of acrosome degeneration. The possibility that removal of the acrosome may not be a morphological concomitant of capacitation in mice has been discussed.

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.
