Summary.

Mouse ovaries were incubated with fsh then removed to fresh medium lacking hormone. At various times after removal, [14C]thymidine was added to the dishes. After 24-hr further incubation, the tissue was prepared for counting. Parallel cultures, never exposed to fsh, received thymidine and were counted simultaneously. The difference in counts between paired fsh-treated and untreated cultures indicated the residual fsh effect. The differences were significant up to 9 hr after removal from fsh, but not thereafter. The results suggest that a constant supply of fsh is needed for the continued growth of early follicles.

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.
