If the beads were placed in one horn only, premature luteal regression occurred only in the adjacent ovary. Induced luteal regression was preceded by an increased release of prostaglandin F2\u03b1 (PGF2\u03b1) from the uterine horns which contained the beads.<\/jats:p>\n                  <jats:p>Oestradiol benzoate treatment of guinea-pigs carrying beads in one uterine horn overcame the unilateral effect and resulted in premature luteal regression in both ovaries. This was also associated with the early release of PGF2\u03b1 from both uterine horns, though a difference in the timing of the release was apparent between the bead-containing (experimental) and control horns.<\/jats:p>","DOI":"10.1677\/joe.0.0680445","type":"journal-article","created":{"date-parts":[[2008,12,11]],"date-time":"2008-12-11T17:22:29Z","timestamp":1229016149000},"page":"445-451","update-policy":"https:\/\/doi.org\/10.1530\/crossmarkpolicy-5","source":"Crossref","is-referenced-by-count":5,"title":["EFFECT OF INTRA-UTERINE BEADS ALONE, OR COMBINED WITH OESTROGEN TREATMENT, ON UTERO-OVARIAN VENOUS PLASMA PROSTAGLANDIN F2\u03b1 AND PROGESTERONE LEVELS IN THE GUINEA-PIG"],"prefix":"10.1530","volume":"68","author":[{"given":"F.
