Journal of Reproductive Medicine, 62(3-4), 184-189.1943-35650024-7758http://hdl.handle.net/11452/33551OBJECTIVE: To evaluate the effect of duration of torsion on ovarian reserve. STUDY DESIGN: Twenty-two female New Zealand rabbits were divided into a sham and 2 study groups. The torsion/detorsion (T/DT) groups had left adnexal torsion for either 3 or 6 hours followed by detorsion. Ovaries were evaluated histologically for follicular damage, and preoperative, predetorsion, and postdetorsion blood samples were drawn from each rabbit to measure antiMiillerian hormone (AMH) levels. RESULTS: Mean primary, small antral, and antral follicle counts were lower in the T/DT groups as compared to the sham group. Primordial, small antral, and antral follicle counts were not different between the 3-hour T/DT and 6-hour T/DT groups. When compared with contralateral ovary, the 6-hour T/DT group had significantly lower follicle count. The 6-hour T/DT group had higher percent change in both predetorsion and postdetorsion AMH levels as compared to the 3-hour T/DT group. CONCLUSION: Although extended time of torsion has negative impact on ovarian reserve, the ovary keeps its viability with functioning follicles after detorsion.eninfo:eu-repo/semantics/closedAccessObstetrics & gynecologyAnti-mullerian hormoneInfertilityFemaleOvarian torsionOvarian reserveOvaryTorsion abnormalityAntimullerian hormone-levelsTwisted ischemic adnexaReperfusion injuryTissueViabilityArticle0003974549000142-s2.0-85015657091184189623-4Obstetrics & gynecologyMechanical Torsion; Salpingectomy; PediatricsMuellerian inhibiting factorAdultAnimal experimentAnimal modelAnimal tissueArticleCell countControlled studyDisease durationFemaleNew Zealand rabbitNonhumanOvarian reserveOvaryOvary follicle cellOvary torsionPriority journalReperfusion injury
