Definition: 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).
Input: Abstract: Seven of 12 patients with retrograde ejaculation, who had at least occasional samples with reasonable sperm numbers and motility, underwent a protocol including luteinizing hormone-timed, intrauterine insemination with washed sperm recovered from the urine. Seven pregnancies have occurred to date in six patients; the one other patient is still early in the protocol period. The described technique for collecting sperm, ovulation timing, sperm recovery, and washing and intrauterine insemination are relatively simple and cost-effective and appear to be effective in contributing to pregnancies in many couples with retrograde ejaculation.
Which is the apt title for the abstract? option1: A simple and effective technique for increasing pregnancy rates in couples with retrograde ejaculation. option2: Gunshot wound of the left chest and Bochdalek hernia.
Output:
A simple and effective technique for increasing pregnancy rates in couples with retrograde ejaculation.
