Given a paragraph, generate a claim that is supported by the given paragraph. 1) The claim must contain information from within the paragraph. 2) A sentence within the paragraph can be used as a claim. 3) The claim should not have contradictions within the paragraph. 4) The claim should be at most one sentence long.

Let me give you an example: "Although the story didn't cite the cost of appendectomy emergency or urgent surgery and we wish it had, we nonetheless will give it a satisfactory score because it at least cited what the editorial writer wrote, ""A secondary benefit is the savings to the hospital generated by minimizing staff and anesthesiologist presence late in the evening and during the wee hours of the morning."" As with our harms score above, although the story didn't give absolute numbers, in this case we think it was sufficient for it to report that ""The scientists found no significant difference among the groups in the patients' condition 30 days after surgery or in the length of their operation or hospital stay."" Although the story didn't give absolute numbers, in this case we think it was sufficient for it to report that ""The scientists found no significant difference among the groups in the patients' condition 30 days after surgery or in the length of their operation or hospital stay."" Despite running less than 300 words, this story did an adequate job in explaining the quality of the evidence, including pointing out limitations. No disease-mongering here. The story meets the bare minimum requirement for this criterion in that it at least cited what an editorial stated. The focus of the story was on a study comparing emergency appendectomy with surgery done up to 12 hours later or beyond. This is the whole focus of the story and one we applaud when it begins: ""Appendectomy is the most common emergency surgery in the world, but it doesn't have to be."" There were no claims made about the novelty of this research, and we may have wished for a bit more context on this. Nonetheless, the potential for guiding future care decisions was made clear. Not applicable. Given that the story only pulled excerpts from the journal article and the accompanying editorial, and didn't include any fresh quotes from interviews, we can't be sure of the extent to which it may have been influenced by a news release."
The answer to this example can be: Some appendicitis cases may not require 'emergency' surgery
Here is why: The paragraph mentions that "Appendectomy is the most common emergency surgery in the world, but it doesn't have to be." which is considered evidence for the output. Thus, the output is a valid claim.

OK. solve this:
Based on samples from more than 6,000 men treated for infertility, researchers writing in American Journal of Obstetrics & Gynecology found sperm in greater numbers, with faster swimming speeds and fewer abnormalities in semen made during the winter, with a steady decline in quality from spring onward. "The winter and spring semen patterns are compatible with increased fecundability and may be a plausible explanation of the peak number of deliveries during the fall," wrote lead researcher Eliahu Levitas from Ben-Gurion University of the Negev in Beer-Sheva. If there is a seasonal pattern, they said, that knowledge may "be of paramount importance, especially in couples with male-related infertility struggling with unsuccessful and prolonged fertility treatments." For the new study, Levitas and his colleagues collected and analyzed 6.455 semen samples from men at their fertility clinic between January 2006 and July 2009. Of those, 4,960 were found to have normal sperm production, and 1,495 had abnormal production, such as low sperm counts. The World Health Organization defines anything over 16 million sperm per milliliter of semen as a normal sperm count. Taking into account the approximately 70 days it takes for the body to produce a sperm cell, the researchers found that men with normal sperm production had the healthiest sperm in the winter. For example, those men produced about 70 million sperm per milliliter of semen during the winter. About 5 percent of those sperm had "fast" motility, or swimming speed, which improves a couple's chance of getting pregnant. That compared to the approximately 68 million sperm per milliliter the men produced in the spring, of which only about 3 percent were "fast." For men with abnormal sperm production, however, the pattern didn't hold. Those men showed a slight trend toward better motility during the fall and made the largest percentage of normal shaped sperm - about 7 percent - during the spring. "Based on our results the (normal) semen will perform better in winter, whereas infertility cases related to low sperm counts should be encouraged to choose spring and fall," the researchers wrote. Previous studies, mostly in animals, have found similar results in line with those species' breeding seasons, said Edmund Sabanegh, a urologist who was not involved with the new research. "The hard part of this is really sorting out what factor is accounting for this," said Sabanegh, the chairman of the urology department at Ohio's Cleveland Clinic. In animal studies, seasonal changes in sperm production and fertility have been linked to factors ranging from temperature, to length of daylight exposure and hormone variations. Among people, previous research has found that sperm counts around the world are falling. While no one knows why, theories range from a more sedentary lifestyle to chemicals in the environment that affect sperm health. Sabanegh said he doesn't think doctors will start telling men with low sperm counts to wait until the winter or spring to try to conceive a child. "We would continue to encourage them to try regardless of the season, and they may benefit from interventions or treatments." SOURCE: bit.ly/13JGdnB
Answer:
Even for sperm, there is a season.
