Coffee common sense: excessive coffee in women can reduce fertility

Coffee contains a lot of caffeine, women's excessive intake can reduce the secretion of estrogen, and the decline in the level of estrogen in the body may adversely affect the ovulation function of the ovaries and reduce the chances of conception.

According to a population survey in the United States, young women who drink an average of more than three cups of coffee a day have a 27% lower chance of getting pregnant than those who never drink coffee, and young women who drink two cups of coffee a day are about 10% less likely to get pregnant than those who don't.

Therefore, medical experts advise young women without children after marriage, it is best not to drink coffee often, especially not to drink a lot of coffee, no more than 2 cups a day. In addition, tea also contains a small amount of caffeine, infertile women should not drink large amounts, no more than 5 cups a day, and to avoid drinking strong tea.

Giving birth helps to improve women's intelligence.

It is generally believed that a woman's brain becomes less sensitive after giving birth. But a new study by US researchers has found that giving birth can help women improve brain function and prevent them from suffering from degenerative diseases in old age.

Craig Kingsley, a professor of neurology at the University of Richmond in Virginia, was quoted by the Daily Mail as saying: "Women do go through a period of so-called 'baby brain' when they feel a marked decline in brain function. But this is because part of their brain function is changing to meet the new challenges ahead."

"these changes start [during pregnancy] and can last a lifetime." "these changes can improve the cognitive ability of mothers and prevent them from suffering from degenerative diseases in old age," he said. "

Test 4 new weapons during ovulation

Now with the latest "weapons" to help women measure your ovulation period, with these new "weapons", you can have a better grasp of your sex life and sweep away all your worries.

1. Computer watch

This kind of computer watch is worn on the hand and can sense the bioelectrical changes of women after menstruation. When ovulation comes, the microcomputer in the watch sends out a "danger" signal to warn the wearer to pay attention to contraception or conception, which is very simple and accurate.

two。 Peripheral blood flow meter

The effect of changes in estrogen levels in the blood supply receptors of human limbs. In general, women's fingers generally reduce their blood flow during ovulation, so their hands become colder. The photoelectric controller of the peripheral blood flow meter can help detect this subtle change.

3. Cervical thermometer

Instead of measuring temperature, it is a rapid determination of guaiacol peroxidase in cervical mucus, which drops sharply 5 to 7 days before ovulation.

4. Test "lipstick" during ovulation

Named because it is shaped like lipstick, it is actually a miniature microscope and a set of light sources used to observe images of estrogen crystals in women's saliva. Female estrogen crystallization can produce three different images in safe period, ovulation period and ovulation period. Through observation, we can confirm the safe period, ovulation period and ovulation period in their physiological cycle.

The more difficult it is to get pregnant, the more likely it is to have a boy.

Luc Smiths, an epidemiologist at Maastricht University in the Netherlands, led a survey of 5283 women who gave birth between July 2001 and July 2003 and found that it took more than a year for them to conceive. The proportion of women who gave birth to boys was 58%, while those who conceived in less than a year had a 51% chance of having boys.

Researchers believe that globally, the birth rate of boys has always been higher than that of girls. This is because sperm with Y chromosomes are smaller and more flexible, so they are easier to bind to eggs through cervical mucus. Previous studies have found that the viscosity of women's cervical mucus varies from person to person, and people with higher viscosity are less likely to get pregnant. So Smiths explained to her findings: "although it is difficult for women with higher cervical mucus to conceive, over a longer period of time, sperm with Y chromosomes are more likely to pass through the cervix and combine with eggs." so you're more likely to have a boy.

Low-income women are more likely to suffer from postpartum depression

A new study from the University of Iowa has found that low-income women are more likely to suffer from postpartum depression than high-income women.

The study surveyed 4332 newborn mothers from four regions of Iowa who gave birth to an average of 4.6 months. Through the survey, psychologist LisaSegre found that family income is closely related to women's postpartum depression: 40% of newborn mothers with a household income of less than $20, 000 have experienced very significant postpartum depression. By contrast, only 13% of newborn mothers have a household income of at least $80,000.

"these 40% of low-income mothers face the dual pressure of depression and poverty." "for them, there is already a lot of pressure from all aspects of life, such as poor living conditions, facing various bills waiting to be paid every day, and the birth of a newborn will bring them new financial and emotional pressure, which will continue to impact them and affect their ability to cope with an already bad environment," Segre explained.

"some studies have shown that women can effectively buffer postpartum depression if they receive strong social support after delivery," Segre explained. "on the contrary, poor social support is more likely to lead to postpartum depression. Previous studies have also shown that Latin American mothers tend to receive more social support, while African-American mothers receive much less social support."
