Objective: This study investigated the mRNA expression of gamma-aminobutyric acid (GABA) receptors in the sperm of oligoasthenoteratozoospermic (OAT) and teratozoospermic (TER) men compared to normozoospermic (NOR) men, as well as the relationships between GABA receptor expression and sperm parameters, fertilization rate, and embryo quality.Methods: The mRNA expression of GABA A-α1 and GABA B-R2 receptors in sperm was examined using reverse transcription–polymerase chain reaction in three groups of patients: NOR (n=32), OAT (n=22), and TER (n=45). The fertilization rate and embryo quality were assessed in 35 patients undergoing Intracytoplasmic sperm injection (ICSI; 10 NOR, 10 OAT, and 15 TER men). Results: OAT men had significantly higher mRNA expression of GABA A-α1 and GABA B-R2 receptors in sperm than NOR men; however, the difference between TER and NOR men was not significant. High levels of these receptors were significantly correlated with low sperm concentration, motility, and morphology, as well as the rate of good-quality embryos (GQE) at the cleavage stage after ICSI. Patients whose female partners had a >50% GQE rate at the cleavage stage had significantly lower levels of GABA A-α1 receptor expression than those whose partners had a ≤50% GQE rate.Conclusion: Our findings indicate that mRNA levels of GABA receptors in human sperm are correlated with poor sperm quality and associated with embryo development after ICSI treatment. The GABA A-α1 receptor in sperm has a stronger relationship with embryo quality at the cleavage stage than the GABA B-R2 receptor.

BACKGROUND/OBJECTIVE: Several studies have reported that consumption of Salvia Hispanica L.,commonly known as chia seed, may exert beneficial effects on health outcomes. The main purpose of this study was to examine the influence of chia seed consumption as a mid-morning snack on short-term satiety. SUBJECTS/METHODS: Subjects (n = 24) were tested using a randomized, cross-over design consisting of three mid-morning snacks. Yogurt with no chia seed, yogurt with 7 g chia seed, and yogurt with 14 g chia seed were given to subjects on different test days. After subjects were asked to report visual analog scale (VAS) scores on sensory outcomes, ad libitum lunch was served, and energy intake of individuals was measured. RESULTS: VAS scores indicated that participants reported significantly lower scores for hunger (P = 0.033), prospective food consumption (P = 0.031), amounts of food that could be consumed (P = 0.017), desire for sugary foods (P = 0.015), and higher scores for satiety (P = 0.031) on the test days with 7 g and 14 g chia seed. Energy intake of individuals during ad libitum lunch was significantly lower when they consumed yogurt with 7 g or 14 g chia seed (P = 0.037). CONCLUSIONS: The study demonstrated that chia seed consumption as a mid-morning snack may induce short-term satiety in healthy individuals.
