Where Can I Find the Monthly Chart for Giving Birth to Boys in 2019?

In traditional Chinese beliefs, having a male child is preferred over having a female child, and even now many families still hope to have a male child. Therefore, many parents are concerned about the month in which to conceive a male child. However, there is actually no significant relationship between the gender of a child and the month of conception. Both boys and girls are equally important to a family and there is not much difference between them; they are both precious treasures to their parents.

Fetal gender identification, also known as gender identification, refers to the use of medical, biological, and genetic theories, as well as techniques such as polymerase chain reaction (PCR) and fluorescent quantitative analysis, to determine the gender of a fetus. This is achieved by extracting and analyzing the fetal DNA chromosomes from a blood sample to detect the presence of the Y chromosome. Gender identification is typically performed by drawing 12ml of the pregnant woman's blood before the birth of the fetus.

There are various techniques for fetal gender identification. Pregnant women can know the gender of their fetus through DNA gender identification methods as early as 7 weeks into their pregnancy, with an accuracy rate of up to 99.4%. Maternal DNA blood testing involves the use of genetic engineering techniques to analyze the mother's venous blood to determine the gender of the fetus. This process poses no risk to the fetus or the mother and relies on chromosome analysis for gender inference.

There are three medically and scientifically proven methods for determining fetal gender: ultrasound, DNA blood testing, and amniotic fluid aspiration. Although all three methods have been medically proven to be effective for gender testing, ultrasound has some drawbacks. Many pregnant women choose to undergo ultrasound to determine the gender of their fetus, with the gender being informed by a gynecologist. However, there are several issues with this method. One is accuracy, which can be affected by various factors such as the type of ultrasound machine (older models may not provide clear images), the position of the fetus (if the genitals are obscured, it can affect the doctor's judgment), and the experience, skill, and seniority of the gynecologist. Therefore, ultrasound has many uncertainties and an overall accuracy rate of only around 70%.

The main harm of illegal fetal gender identification lies in the serious imbalance it causes in the gender ratio, which hinders the healthy development of the population, triggers family conflicts, and induces criminal acts such as trafficking in women, rape, arranged marriages, and prostitution, thereby disrupting the harmony of social order.
