Studies have shown that whether the father-to-be is physically tired or not will affect the female partner’s ability to have a male or female child. The reason is that although the sperm is petite and agile and swims fast, it has a short life span, is more fragile and has a weak ability to adapt to the environment. If the father-to-be often works overtime, stays up late, smokes, drinks and is too tired during conception, it will lead to the loss of sperm, or lack of vitality and inability to cross the sticky cervical mucus to meet with the egg, and the X sperm, which has more endurance and longer life span, will prevail. Therefore, the father-to-be is prone to have a girl when he is physically fatigued; the father-to-be who has an easy job is more likely to get a boy. Professionally, men with busy and stressful jobs have a high probability of having a girl, such as bosses, professional managers, engineering designers, drivers, pilots, anesthesiologists, etc.; while men with a good mindset and easy work have a high chance of having a boy.

Extended reading: The ability of men to produce sperm Women’s menopause, has been widely recognized by the medical community and society. It is the female genitalia – ovarian function by the gradual decline to the final disappearance of a transitional period. The basic physiological change of this process is the diminished function of the ovaries to secrete estrogen, the most prominent manifestation of which is menopause. The age of onset is generally between 45 and 55 years. In men, however, the decline in reproductive function is gradual and remains normal even in old age, with the ability to reproduce still present. A man’s ability to produce sperm lasts until he is 90 years old, or even longer. Men also have menopause. There are also gradual changes in the function of the testes, a slow decline in pituitary gland sex hormones, and a decrease in androgen secretion from the adrenal cortex. As the function of the various endocrine glands in the body decreases, the demand for the endocrine hormones required by the various organs under their control becomes unbalanced, resulting in various uncomfortable symptoms. However, unlike women’s ovaries, men’s testicles do not shrink as easily, and their function decreases gradually, so the secretion of androgens decreases gradually, unlike women, whose estrogen decreases suddenly with the cessation of menstruation. It is generally believed to be slightly later than in women, but there are individuals who occur around 40 years old or as late as 70 years old. Once a middle-aged man finds his physiological functions declining, his physical strength decreasing requiring more time for rest, and he starts to feel his sexual function declining, often with a series of changes such as dizziness, depression or uncoordinated behavior, it means he is starting to enter the last turning point of his life – menopause.
