Pregnancy gets weirder as we get rounder. What really goes on under wraps during those nine-plus months? From a hidden bias involving swelling bosoms to fetal cells in maternal brain, scientists have found a mother lode of surprising phenomena. Here are seven discoveries nobody really expects when she’s expecting.
Pregnant Women Are Sexy! - Many expectant moms think pregnancy makes them look less attractive. Most men disagree. In one study, 60 percent of men maintained the same level of sexual desire for their partners, and 27 percent of men expressed increased desire.
Your Breasts Grow Larger If You’re Expecting a Girl - Contrary to popular belief, the shape of your belly -watermelon or basketball — doesn’t reveal anything about the baby’s gender. But your shape above the belt might. Women carrying girls grow larger breasts during pregnancy compared to those carrying boys. Male fetuses produce testosterone which may suppress breast enlargement.
If You Dream About Your Baby’s Gender, You’re Likelier To Be Right - Surprisingly, pregnant women who have a dream in which their baby’s gender is revealed, or a strong feeling about whether their baby will be a boy or a girl, are more accurate than by chance. Women’s intuition is supported by science!
Nightmares Are Linked With Faster Deliveries - Women who have had vivid dreams during pregnancy have shorter labors than non-dreamers — by nearly an hour on average. Among the dreamers, those who had nightmares (unpleasant dreams) in third trimester had even faster deliveries and a decreased chance of postpartum depression than those who had good dreams only. The purpose of dreaming may be to help us resolve internal conflict and process new information, which leads to psychological preparedness for the baby’s birth.
Skinny Women Are Likelier To Have Daughters - Skinny chicks have more daughters. Many studies show a slight but statistically significant difference in the gender ratio between women who are underweight and normal weight. The explanation: Female embryos are hardier than males, and therefore more likely to survive in a less hospitable environment — resulting in more female births among the super-skinny. This is an observation that shows up on a population level; it’s not a reliable method of gender selection. Starving oneself endangers the fetus.
Your Body Odor May Affect Your Partner Subconsciously- By the third trimester, pregnant women’s sweat contains new chemical compounds (pheromones). No one knows for sure why these chemicals show up at this time and disappear shortly after giving birth — they may help the newborn identify her mom — but there’s room for more speculation. The subtle odor may subconsciously trigger one’s partner to produce hormones such as prolactin that facilitate bonding and preparedness for fatherhood. Men with the highest prolactin levels around the time of the baby’s birth are more nurturing than men with lower levels of the hormone
Your Baby’s Cells Stay In You For Life - During pregnancy, cells sneak across the placenta. The fetus’s cells enter the mother and the mother’s cells enter the baby -and stay there for life. In mothers, fetal cells often take residence in her lungs, spinal cord, skin, thyroid gland, liver, intestine, cervix, gallbladder, spleen, lymph nodes, and blood vessels. The baby’s cells may also live a lifetime in Mom’s heart and brain. Implicated in health and disease, fetal cells may also behind some of the mind-shifts that happen in motherhood.
