Article Synopsis
- Microplastics have been found in the semen of men from polluted areas, raising concerns about their effects on human health, particularly reproductive health.
- A study in Jinan, China analyzed semen samples from 40 men with no occupational exposure to microplastics, revealing an average of 2 microplastic particles per sample, primarily polystyrene.
- The study indicated a correlation between sperm motility and exposure to certain plastic types, specifically showing better motility with polystyrene compared to polyvinyl chloride, highlighting the need for more research on how microplastics may impact human reproduction.
The aim of this study was to improve the quality of semen samples by using a novel double-tube (DT) method. The DT method was developed to select sperm and compared with traditional swim-up (SU) technique for 31 semen samples. Sperm DNA integrity were tested with TUNEL and SCSA.

The current study aims to elucidate whether seminal microbiota exist in patients with different types of dysspermatism and whether bacterial biomarkers can be identified for them.

Objective: To explore the association between parental genetic polymorphism of methylenetetrahydrofolate reductase (MTHFR) 677C/T and occurrence of nonsyndromic cleft lip with or without cleft palate (NSCL/P) in offspring in Shandong Province.
Methods: MTHFR genotypes were determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Parents of 89 NSCL/P patients treated at Qilu Hospital from August, 2006 to August, 2008 and those of 64 healthy children were recruited in this case-control study.
Objective: To evaluate the clinical effectiveness of preimplantation genetic diagnosis (PGD) for the couples having a higher risk of genetic diseases with fluorescence in situ hybridization (FISH).
Methods: Ovarian hyperstimulation, oocyte retrieval and in vitro fertilization were performed in 4 cases. Blastomere biopsy were performed from the embryos at the 6 - 8 cell stage.
