Answer

Anatomic changes affecting the weight and the size of the ovary may alter the position of the fallopian tube and allow twisting to occur.

Pregnancy is associated with, and may be responsible for, torsion in approximately 20% of adnexal torsion cases, [7] probably secondary to the ovarian enlargement that occurs during ovulation in combination with laxity of the supporting tissues of the ovary.
