You will be given a definition of a task first, then some input of the task.
Given an abstract, indicate which of the provided candidate titles (Option1 and Option2) best describes it (respond with the text of the title, not option1/2).

Abstract: A prospective study of six unselected couples diagnosed as having unexplained infertility was done. In three of six patients, subtle abnormalities in follicular development were detected. In the first case poor follicular growth was observed. There was a premature small rise of luteinizing hormone (LH) with subsequent low levels of estradiol (E2) in the late follicular phase and unusual wide LH peak. This was followed by low progesterone levels in the luteal phase. In the second case follicular growth was abrupted by premature LH surge. This surge was triggered by early rise of E2 level while the follicle was still small in size. In the third case luteinized unruptured follicle syndrome was diagnosed, on ultrasound examination. All of the abnormalities were repetitive.
Which is the apt title for the abstract? option1: Subtle abnormalities in follicular development and hormonal profile in women with unexplained infertility. option2: Computed tomographic pelvimetry.
Output:
Subtle abnormalities in follicular development and hormonal profile in women with unexplained infertility.
