In vitro fertilization (IVF) is one of the most innovative methods for managing infertility and uses assisted reproductive technology (art), to increase the chances, that you will present. It is a process that the eggs fertilized by sperm outside the womb. IVF is an important treatment infertility when other methods of assisted reproduction have failed. This process involves hormonally controlling ovulatory process, removing ova (eggs) from the woman ovaries and sperm that fertilize in a liquid medium they can. The fertilized egg is then inserted into the patient’s uterus with the intention that a successful pregnancy make transfer. A women-weight can impair their fertility. Obesity leads to reduced fertility in women with irregular menstrual period. Again, obesity leads to increased production of estrogen-this hormonal imbalance disrupts ovulation, which is the basis for successful conception. To lose weight, while decreases the hormonal effect of excess fat. This can result in a substantial increase in your fertility. Women, overweight and trying to become pregnant are IVF expect even better results if they lose weight. It would have a significantly better chance of success if you reduce your weight through weight loss surgery. Obesity during in vitro fertilization (IVF) patient cancellation has allocated higher clock rates were, reduced live birth rates and increased miscarriages. In addition, rather obese women are complications including increased demand for the induction of labor, greater utilization of instrumental delivery and a higher risk for emergency cesarean section, premature birth, fetal macrosomia to meet delivery. Obese women should therefore check the importance of weight loss and effective strategies against the prejudice to own. Another problem related to body weight and IVF is safety for the patient during the egg retrieval. If a woman is significantly overweight, the ovaries are usually high up down by the additional fat that is in the basin. At the time of IVF the needle is pushed to reach the eggs in the ovaries, and if the ovaries are too high, it will be very difficult to get out of the needle into the follicle the eggs. Another problem is that the ultrasound pictures because of the extra fabric in the ovary become very blurred. It is often very difficult, the ovaries and the egg follicles containing to make clearly visible. Woman, the obese (BMI over 30 and higher) and pollination is, has less prospect of success and higher likelihood of miscarriage rates. Before carrying out IVF, patients should know the impact of obesity on their IVF success rates. And weight loss through bariatric surgery can a dramatic effect on improving the chance of a successful pregnancy. Proper exercise and diet are important for maintaining good health and adequate. Couples, the babies can have obesity surgery. Patients who undergo weight-loss surgery improve the ability to conceive after having IVF. Reproductive hormone levels are restored normal only after weight-loss surgery.
