This study suggests that a history of previous birth defect-affected pregnancy, a history of maternal fever or cold, use of analgesics, antipyretics, and oral contraceptives, exposure to passive smoking, folic acid use, and consumption of fresh vegetable and fruit may be associated with NTD risk.

The galectin-3 genetic polymorphisms of galectin-3 +292, rather than galectin-3 +191, were associated with the chemotherapy response and prognosis of NSCLC.

The present study aims to analyze sperm concentration trends among young and healthy Chinese adults in Wuhan, Central China, from 2010 to 2015. Semen analysis data from 9357 participants were collected and analyzed using a general linear model and the Cochran–Armitage trend test. A significant decline was observed in sperm concentration (β [standard deviation]: −1.53 [0.16]; P < 0.001). In addition, a decline in sperm density was observed by stratifying student versus nonstudent sperm donors and by analyzing the year of birth or birth year cohort of the participants. Furthermore, the percentage of participants with sperm densities of over 40 × 106 ml−1 significantly decreased with year. Notably, a dramatic decline in sperm density was recorded over the first 5 years of study. This research reported a decline in sperm concentration among young adults in Wuhan, Central China, in 2010–2015.

We found a birth cohort effect on sperm count and morphology among Danish infertile men born after 1950 but not in men born in the first part of the century. The findings are compatible with an environmental impact during prenatal life but the evidence is far from unequivocal.
