Want a boy but get an infection
A lady who wants to have a boy eventually has vaginal yeast infection after she washed her vagina with sodium bicarbonate solution for a time. So sad a true story.
It is impossible to take a randomized clinical trial to test this method, but of which the effect is bad according to medical knowledge. Vaginal acidity is necessary to prevent infections and the normal pH value shouldn't be changed purposely.
Why is there such a horrific method for gender selection? Â Let's see an animal experiment in 1934, which type of research can't produce evidence directly for human beings.
EFFECTS OF FEEDING SODIUM BICARBONATE OR LACTIC ACID UPON THE SEX RATIO IN RATS
SEVERAL articles have appeared recently in the newspapers to the effect that the ingestion of sodium bicarbonate during pregnancy influences the sex of the offspring both in the human and in the dog, males being produced exclusively.
We conclude that, for the rat at least, the sex ratio is not affected by the feeding of base or acid.
Further, more targeted animal experiments happened inevitably in the late 1930s.
THE EFFECT OF LACTIC ACID AND SODIUM BICARBONATE ON THE SEX RATIO
Douching females with lactic acid before mating was effective in increasing the proportion of females, while the use of sodium bicarbonate increased the proportion of males.
However, human ≠experiment using rat. Now see an in vitro laboratory study in 2017, which type of research can't produce evidence directly for or against any lifestyle change for sex selection, but which often also provides a review of its topic.
Environmental Exposure of Sperm Sex-Chromosomes: A Gender Selection Technique
(Introduction) Sex selection can be achieved through natural conception, although this option is not well-established yet and therefore, remains quite speculative. However, influencing the timing of fertilization with regard to ovulation is one of the natural methods believed to be effective. Sex selection through timely intercourse is based on the respective characteristics of the X- and Y-chromosome-bearing spermatozoa, favoring one or the other toward reaching and fertilizing the egg.
The results indicated enrichment of Y-sperm at pH 6.5, 8.5, or 9.5, but poverty at pH 5.5 (neutral 7.5), increased temperatures, and elevated H2O2.
Preconceptual sex selection… X- and Y-chromosome-bearing spermatozoa (motile sperm cell) are isolated prior to fertilization of the oocyte (egg cell).
The aim of this study was to separate X- and Y-chromosome-bearing spermatozoa using methods based on the viability difference between the X- and Y-chromosome-bearing spermatozoa.
Spermatozoa were exposed to different pH values (5.5, 6.5, 7.5, 8.5, and 9.5), increased temperatures (37°C, 41°C, and 45°C) and ROS (reactive oxygen species) level (50 μM, 750 μM, and 1,000 μM).

At any rate, listening to a specialist of OB/GYN is necessary:
Is there any way to influence a baby's sex?
The short answer is no — there's not much the average couple can do to affect a baby's sex.
In short, don’t try any method not recommended by clinicians.
