Do “neurotic” men and “manly women” have fewer children or no offspring? A recent finding by British and Finnish researchers shows that personality affects fertility. Researchers suspect that this is related to hormonal and emotional barriers to fertility, and that personality also affects an individual’s perception of marriage and fertility, indirectly affecting fertility. The reporter learned from the hospital in Guangzhou that there is also the phenomenon of “personality causes disease” among patients with habitual miscarriage and infertility. For couples whose “baby-making” plans are frequently unsuccessful, in addition to examinations to rule out organic pathologies, it is important to pay attention to the impact of personality, emotions and other psychological factors on fertility. Two types of personalities are not conducive to having children. According to reports, British and Finnish researchers examined the fertility of more than 7,000 residents born in 1927-1968 and found that there is a relationship between personality and a person’s fertility. Compared with stable, outgoing and open-minded men, moody, moody, emotionally fragile “nervous” men are more likely to have no offspring or a relatively small number of children. And old-fashioned, serious, ambitious “masculine” women, and gentle and delicate, showing more feminine qualities of the same sex, compared with fewer children. Researchers believe that the impact of personality on fertility, on the one hand, may be related to hormones. People who have high mood swings and are prone to stress and anxiety are more likely to have hormonal disorders, which in turn affect reproductive health. On the other hand, people with the above-mentioned personalities are generally reluctant to get married too early and have children, and tend to marry later and have children later, which may cause infertility due to missing the optimal age of fertility. When people with these personalities get married, their relationship may be affected, even leading to a higher divorce rate, which indirectly affects fertility outcomes. “Masculine” women are more difficult to have children. There is a correlation between personality, emotions and fertility. We have observed a similar phenomenon in patients with habitual abortion and infertility. For example, women who are masculine, ambitious and easily provoked are more likely to experience infertility and miscarriage. For one thing, “masculine” women tend to have higher levels of androgens in their bodies. These women are mostly successful in the workplace, and success requires more physical and mental effort, “high androgen levels can make people more energetic and more motivated.” However, high androgen levels can also make it difficult for women to ovulate, making them unable to have children or prone to miscarriage. Women with polycystic ovary syndrome, for example, have high androgen levels that can affect their fertility. “Masculine” women are also at high risk for hyperthyroidism. Dr. Liu Zhonglin, deputy chief of the Department of Neurology at Sun Yat-sen Memorial Hospital, Sun Yat-sen University, points out that hyperthyroidism can cause fertility problems. At the same time, “masculine” women tend to be more career-minded and enjoy single life more, and many of them marry late and have children late, which can also have a negative impact on fertility. Many career-oriented women ignore the laws of human fertility, and once they miss the prime time to have children, even if they can seek the help of assisted reproductive technology, the success rate is not as high as expected. In fact, the overall success rate is only 30%, with only 10% for those over 40 years of age, and the majority of those who return with regrets. Women: Irritable people are at high risk of infertility and miscarriage On the other hand, excessive mood swings can also have an impact on a woman’s fertility. “Emotions can affect the function of the female hypothalamus, making estrogen and progesterone levels high or low. And this is not conducive to conception. “Some people think that high estrogen levels are good for fertility, which is also wrong.” Some women with polycystic ovary syndrome also have higher levels of estrogen, but this can also cause ovulation disorders and a higher than normal risk of miscarriage, even if they do get pregnant. For women, dramatic mood swings can cause miscarriages and premature births. “When we are on the night shift, we can often encounter pregnant women who are in extreme anger because of a big fight with their family, causing contractions and miscarriage.” People who are easily angered are prone to tension, and in a state of stress, blood vessels constrict. For women in early pregnancy, vasoconstriction can cause a lack of local blood supply, which can trigger a miscarriage. Women in late pregnancy may also experience premature labor due to uterine contractions triggered by angry tension. Men: changeable and nervous people are difficult to raise offspring Men who are changeable, moody and emotionally fragile are often considered to have an “artist temperament”, but men with this personality are not so “reliable” for raising offspring. Men have an important responsibility to take care of their families and raise their offspring. Stable and outgoing personalities, regularity and a sense of responsibility will help men to better take care of their families and offspring.” Liu Zhonglin pointed out that “neurotic” men who are moody and unpredictable tend to live irregularly and do whatever they want, which are not conducive to raising offspring. The “artist temperament” of men is likely to not have a strong concept of marriage and family, self-centered, preferring single life, with a tendency to marry later and have children later. People with volatile emotions and mood swings tend to have poor interpersonal communication skills or have interpersonal barriers. They rarely take the initiative to seek help and support from friends when they encounter problems, making it difficult to release psychological pressure in a timely manner, which can also lead to fertility disorders to some extent. For example, long-term workload, people’s psychological stress is too much, prone to mild depression, and a major manifestation of depression is low libido, can not be interested in intercourse, thus leading to low fertility. In addition, men with mood swings are also at higher risk of developing hyperthyroidism, which can also interfere with fertility. In addition to the treatment of organic pathologies of the reproductive system, it is also important to pay attention to the impact of psychological factors such as personality and emotions on fertility when experiencing a fertility crisis. Couples should complete their “baby-making” plans at a stage suitable for childbirth, and try to avoid missing the prime fertility period due to the pursuit of career, which will increase the difficulties of childbirth. During the active preparation period and the waiting period, couples should maintain a peaceful state of mind, not to force, to be tolerant of things, such as not to be paranoid about creating the “perfect baby” at a specific time, not to require the same bright performance in the career during pregnancy and before pregnancy, to avoid being affected by anger, tension and other negative emotions.
