You can make sure you become pregnant with a son by using the Shettle's Method

By timing when you have intercourse you can control if you will become impregnated with a male ( how to conceive a boy ). There is a system known as the Shettles’ method that is based on scientific evidence for gender selection.  The main idea of his model is that when couples learn how to time intercourse accordingly to ovulation they can influence the sex of the baby.  The sperm transporting male chromosomes are speedier swimmers than the female sperm but tend to die more quickly. Becoming pregnant with a male baby is slightly more likely if you have sex at the precise time of ovulation. By having intercourse a few days earlier than the specific time of ovulation the majority of the male sperm will die out. A male sperm will most likely fertilize the ovum if you have intercourse 12 hours before ovulation.  If you have sex during your pre-ovulation phase make sure that you utilize a condom to lessen the risk of female sperm having the upper hand and you becoming impregnated with a girl.  This low-tech method is noninvasive and it is very affordable to find an ovulation predictor kit or to check your basal body temperature daily.   Proponents of the Shettles’ method claim the technique is 80% effective at conceiving a boy baby.

A high calorie diet provides greater chances of getting pregnant with a boy.

 The Exeter completed research on 740 British ladies who had not given birth before and who did not know the sex of their fetuses ( howtoconceiveaboynaturally.com ).  During the time that the women were trying to become pregnant and during the beginning stages of pregnancy they provided written records of what they ate.  The study  revealed that 56 percent of the women on a high calorie diet conceived baby boys. The explanation is thought to lie with the evolutionary drive to produce descendants. In industrialized countries there has been a noted drop of the birth of boys compared to the birth of girls. This is believed because there has been a reduction in the average calorie intake in the developed world. Researchers show that women in western countries tend to give birth to baby girls more due to their inactive routines that causes them to eat food with less calories.  When less food is consumed this can give a false signal of lack of food and calorie availability and may cause the body to develop a female embryo. Pregnant women must increase their usual daily calorie intake by at least 400 calories to conceive baby boys.

There have been numerous studies to aid us in knowing how to conceive boys.

 By fully grasping the details of fertilization you will be better able to have a son. For some individuals conception comes in without any difficulties while some may need special procedures to attain it ( have a male child ).  Infertility is the biological inability of a person to contribute to conception. The methods of treatment for infertility may be grouped as medical or complementary and alternative treatments. One home conception implement that can help with fertilization and conception of a male is known as the cervical cap insemination method. This at home method allows all the semen to be positioned against the cervical area for six hours which makes conception of a boy far more probable. Fertility medications may be prescribed if conception is not occurring even though both the sperm and the reproductive organs are healthy. Another way to medically help conception of a boy is when a physician introduces spermatozoa into the uterus during ovulation via a catheter. If conservative medical treatments fail to achieve a full term pregnancy the physician may suggest the patient undergo in vitro fertilization of male sperm.
