Q: Indicate the presence of numerical data in the abstract (whether numerical data plays a key role in medical records), solely using the information from the abstract.
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.
Question: Does the abstract contain any numerical data?
A:
Yes
