title: Food intake and social habits in male patients and its relationship to intracytoplasmic sperm injection outcomes.
abstract: OBJECTIVE
  To investigate the influence of the male partner's lifestyle, including eating and social habits, on semen quality and intracytoplasmic sperm injection (ICSI) success.
  
  
  METHODS
  Observational study.
  
  
  METHODS
  Private fertility clinic.
  
  
  METHODS
  Two hundred fifty male patients undergoing ICSI cycles.
  
  
  METHODS
  We recorded dietary and social habits using a food frequency questionnaire adapted to meet specific study objectives. Evaluation of semen parameters and ICSI outcomes were performed.
  
  
  METHODS
  Frequency of intake of food items and social habits were registered on a scale with five categories ranging from no consumption to repeated daily consumption.
  
  
  RESULTS
  The sperm concentration was negatively influenced by body mass index (BMI) and alcohol consumption and was positively influenced by cereal consumption and the number of meals per day. The sperm motility was also negatively influenced by BMI, alcohol consumption, and smoking habit, whereas it was positively influenced by the consumption of fruits and cereals. The consumption of alcohol had a negative influence on the fertilization rate. The consumption of red meat as well as being on a weight loss diet had a negative impact on the implantation rate. In addition, the consumption of red meat and being on a weight loss diet had an effect on the pregnancy chance.
  
  
  CONCLUSIONS
  Couples seeking assisted reproduction treatments must be advised about the drastic effect of both the male and female lifestyle on treatment success.
