The Journal Of General Medicine A Quarterly for the Physician


My study of 7,810 patients for the ionic method of sex selection is based on the original study by Dr. Stolwoski and Dr. Lorrain published in the International Journal of Obstetrics and Gynecology. The original study protocol has been modified to suit Indian habitat and style of living along with the difference in the physiology of existing human race. A modification of the four basic elements in our diet i.e. sodium, potassium, calcium and magnesium two months before the planned conception, followed by a specific time period for intercourse in the target cycle results in around 97% success rate in achieving the pregnancy of the preferred sex. The method is totally safe, non invasive, economical and safely done at home with once a month consultation or correspondence based guidance by the doctor. The method is devoid of any side effects.


Any method by which the sex of the body can be selected before the onset of pregnancy is called pre conceptional sex selection. Out of the several methods that were used over decades, the only method time tested and almost sure method is sex selection by ionic equilibrium, i.e. modification of diet before pregnancy.

Morals And Ethics

n contrast to sex determination, sex selection is legal. A patient for sex selection is accepted only if they have a child of the opposite sex, the only exceptions being patients, who are at risk of conceiving a child with genetic disorder due to sex chromosome linked disorders.

Principle Of The Ionic Equilibrium

According to the research by Jacques and Stolwoski, the diet of the woman has total and drastic effect on the sex of the child to be conceived. This was based on the study that the pellucid membrane which surrounds the ova has certain receptor sites on which the spermatozoa bind and may fertilize the ova. The ratio of potassium/calcium, magnesium has an effect on the molecular biology of the receptor sites. This effect is termed as Allosteric Modification which causes specific changes in the membrane compound. These changes in the receptor sites effect the selective attraction towards X sperms or Y sperms, due to variation in the intensity of potentialities on the sperms of both kinds.

To simplify the matter, if a woman is given a high calcium, high magnesium, low sodium, low potassium diet for a period of 6 to 8 weeks prior to conception, her receptor sites on the ova shall attract only X sperms and repel the Y sperms, resulting in a conception of female child.

To reverse the matter, if a woman is given a high sodium, high potassium, low calcium, low magnesium diet for 6 to 8 weeks prior to conception she will attract only the Y sperms and repel the X sperms, resulting into conceiving a male child. Here I would like to mention that though actually only the ratio of potassium to calcium and magnesium is important, the sodium contribution is important as it represents the natural physiological means of controlling potassium metabolism by acting on the superarenal glands, a salt overcharge puts the glands at rest and a deficiency causes hyperactivity.

Principle Of Timing Of Intercourse

Though the timing protocol has got not much of success rate, it has been combined with the diet method. This is based on the fact that Y sperms are lighter and they swim faster than the heavier X sperms. So if the intercourse happens immediately after the ovulation the probability of abundance of Y sperms is present. In contrast to this if the intercourse happens 24 hours or more before the ovulation there are chances of abundant X sperms.This method also helps in catching cases of subfertility due to ovulation disorders and hastens up the treatment schedule of sex selection.

How To Go About The Procedure

The patient is supposed to start the treatment modality roughly 2 months before she wants to conceive. Before the diet plan is given to the patient, the following pre requisites are absolutely necessary.

Her following blood test report:

  • 1. (a) Serum Sodium, Serum Potassium [For Male Child] (b) Serum Calcium, Serum Magnesium [For Female Child]
  • 2. Blood Pressure Recording
  • 3. Weight
  • 4. Date Of Last Menses

After I have the above database on my patient, based upon the specific individual parameters, a customized diet is charted out for her. This diet can be supplemented by additional nutritional supplement when necessary. The patient has to be on the diet and supplement till she conceives. But the diet and the supplement take at least 6 to 8 weeks to act on the ovaries. So starting from the onset of the diet, contraception has to be used till the patient finishes her first two menses. After that she enters what is referred to as the target cycle; the cycle in which she is supposed to conceive. In the target cycle she is supposed to have intercourse on certain specific days depending upon her individual plan of action chart. As mentioned earlier the intercourse has to be after ovulation in case of male child selection, whereas it has to be 24 hours before if a female child is desired. The exact time has to be charted out which varies on case to case basis for all patients.

It is mandatory that the patient should not stop the diet till she is confirmed to be pregnant by a blood or a urine test in a pathology laboratory or a reliable home pregnancy kit which should not be done for at least 4 days after the date of the expected periods.

The total number of cases that I have done from October ’93 to August ’98 is 7,810. This includes 6,400 patients for male child selection and 1,410 patients for female child selection.

Out of the 6,400 patients treated for male progeny, I have achieved success in 6,208 patients, resulting in a success rate of about 97%.

Out of the 1,410 patients treated for female progeny, I have achieved success in 1,355 patients, resulting in a success rate of about 95%.

The combined success rate is 96% (Tables 1, 2 and 3)

Other Methods

Over several decades many methods have been tried out but none of them have any significant success rates and most of them have been abandoned a long time back. Table 4 shows comparative results of different methods.
