Many men who are facing “male factor infertility” because their sperm’s size and shape is not of a high enough quality to fertilize a woman’s egg and help her become pregnant turn to lifestyle changes like losing weight or quitting smoking or drinking alcohol. But a new study published in the journal Human Reproduction has found that those lifestyle adjustments–while a good idea for men who want to be healthier and lower their risk of other health conditions–aren’t likely to help solve their sperm quality issues.
Other factors, including smoking marijuana, were found to lower sperm quality, as was collecting samples during the hot summer months. And the size and shape of sperm–known as “morphology”–was better among men who had abstained from sexual activity for a few days before collection. Reuters has more:
The researchers found that men were about twice as likely to have abnormal sperm if the sample was collected during the summer. They were also more likely to have abnormal sperm if they were young and smoked marijuana.
Although most other medical and lifestyle factors, such as cigarette smoking and alcohol consumption, didn’t seem to be linked to sperm morphology, Smith said he still would advise his patients to be as healthy as possible.
“Marijuana is certainly a potential worrisome risk factor for hurting sperm quality,” he said. “I’d tell my patients to stop smoking marijuana. I wouldn’t say to my patient to go out and do whatever you want because it won’t make a difference. To me, that would be overstating those results.”
The researchers also caution that the men included in the study may not be representative of all couples with fertility problems.
Smith said a better study would be to focus on whether the couples went on to conceive a child.

A major doctor’s group is urging obstetricians to have serious, often difficult conversations with their patients, telling them that being overweight or obese can have negative impact on both their fertility and their pregnancy health. More from Time.com:
The latest news about the negative effects of our nation’s obesity epidemic on everything from fertility to pregnancy and maternal mortality recently prompted the American College of Obstetricians and Gynecologists (ACOG) to urge doctors to talk with patients about the benefits of slimming down before trying to conceive. It’s part of an ongoing push to make chats about women’s “reproductive lifespan” as routine as an annual pap smear. Just as doctors have historically shied away from telling women that their eggs are getting too old, many haven’t been eager to point out that a woman’s size might come in between her and her dream of becoming a mother.
“For a woman who’s been trying for a year, the last thing she wants to hear is to take another year off to lose weight,” explains Dr. Jeanne Conry, ACOG president and assistant physician in chief at The Permanente Medical Group in Roseville, California. “But if a woman walks into my office who’s been trying to get pregnant and she has a body mass index of 30 or over [more than 180 pounds for a 5’5” woman] and she’s having an irregular period, the first thing we’re going to do is discuss a healthy diet and exercise program.”
Of course, doctors point out that the majority of the estimated 30% of obese women in the U.S. have no problems conceiving. But there’s a growing body of evidence that’s difficult to ignore. Obesity raises a woman’s risk of gestational diabetes, hypertension, premature delivery, miscarriage, and stillbirth. A mother’s chance of having to undergo a caesarian section is 34% if her BMI is over 30, and 47% if her BMI is over 35—compared to 21% for women with a BMI under 30, according to one study. There’s even evidence that babies born to obese women have a greater chance of suffering neural defects than those whose mothers are normal weight, and will be at greater risk of being obese themselves.
In one recent survey of more than 3,300 women, one-third responded they didn’t believe or were unsure whether a woman’s weight affected her chances of conceiving. The doctors’ organization hopes that encouraging ob-gyns to broach the topic will educate women about that connection, considering that about 6% of infertility is due to obesity (another 6% is due to being too thin), according to statistics by the American Society for Reproductive Medicine. (That goes for men, too, since a recent French study showed their excess poundage contributed to low sperm production.) The good news is that 70% of these women will get pregnant naturally after they lose or gain enough weight to get closer to a healthier BMI.
The other goal is to help patients set and achieve weight-loss goals, or even consider weight loss surgery if they’re severely obese. But adding those expectations on top of conceiving can feel daunting to many women, says Julie Friedman, PhD, a psychologist who directs a weight management program comprised of counseling, workshops, and support groups, at Insight Behavioral Health Centers, a chain of outpatient mental health treatment centers based in Chicago. “They’ve struggled with their weight their whole lives and now they’re going through something so stressful, saying ‘Now you’re telling me to lose weight when I’m this stressed out and trying for a baby?’”

Women who have had bariatric surgery as a weight loss solution may face an elevated risk of some pregnancy complications, including giving birth to babies who have low birth weight and are born prematurely, a new study has found. More from The New York Times:
The authors of the research, published in BMJ, looked at roughly 15,000 births that took place in Sweden between 1992 and 2009, including about 2,500 among women who had had had weight loss surgery. On average, the women delivered about five years after the surgery.
After controlling for age, smoking and other factors that could influence pregnancy complications, the researchers found that 10 percent of children born to women who had undergone bariatric surgery were delivered prematurely, compared with 6 percent in the other group.
A similar pattern was found for low birth weight. Five percent of children born to mothers in the surgery group were small for their gestational age, compared with 3 percent in the other group.
The researchers speculate that the trends could be driven by deficiencies in vitamins and minerals, which occur after bariatric surgery and could affect fetal and placental growth.

At 9 years old, Breanna Bond weighed 186 pounds, a number that had her doctor and her family alike worried for her health in an age of childhood obesity and rampant Type II diabetes that affects an estimated 12.5 million U.S. children. As CNN.com reports, the involvement of the whole family was the key motivating factor that helped Breanna shed 65 pounds:
“Conversations about a child’s weight can be fraught with psychological landmines, says Dr. Denise Wilfley, director of the Weight Management & Eating Disorders Program at Washington University School of Medicine.
“Mainly what we suggest is actually having the whole family take on a healthier lifestyle — for everybody to eat as well as possible, as nutritiously as possible, so the overweight child is not singled out,” she says.
Wilfley encourages parents in her programs to “walk the walk” and be a role model for their children. She talks about food as energy for kids’ bodies — eating better will help them think harder, jump higher, play more.
Her families try to follow the traffic light diet, with green-light foods such as vegetables, yellow-light foods such as lean protein and red-light foods such as sweets or simple carbohydrates.
“We focus a lot on not defining self-worth by the number on the scale,” she says. “The best way to prevent eating disorders is having very healthy eating patterns.”
[Heidi] Bond realized that in order to get [her daughter] Breanna to exercise regularly, they would had to make it a family activity. The Bonds started walking four miles, four days a week, on a trail near their home in Clovis, California.
“It was the hardest thing I’ve ever had to do,” Bond says. “There were times where she refused to move.” But in the end, “a little tough love to save the rest of their life” was worth it, she says.
It’s best to avoid a power struggle when it comes to exercise and healthy eating, according to Jelalian. She says it’s easy for parents to become the “food police” without getting at the deeper issues. Parents should ask why a child wants a certain food or doesn’t want to work out and problem-solve with them to find a healthy alternative.
She recommends parents give their kids a choice as much as possible — not about being active or not active, but about what activity they want to do.
“It really takes that balance in parenting of being firm — this part is not negotiable, but being warm, caring in how you do that.”
Identifying your child’s motivation for losing weight is key, Wilfley says. Do they want to be able to run faster? Play football? Avoid teasing at school? Combining that goal with incentives such as sleepovers or family outings should help to keep a child motivated.”

On the premiere episode of Katie Couric’s new talk show Katie, singer and fashion designer Jessica Simpson revealed her post-baby body for the first time since she disclosed that she was struggling to lose pregnancy weight and seeking help from Weight Watchers–and is now a spokesperson for the company–to shed the pounds.
On the show, Simpson disclosed that she’s lost more than 40 pounds, and that she is 10 pounds from her pre-pregnancy weight. Simpson’s daughter Maxwell Drew was born May 1.

A new outlook on food has helped.
“The only fish I ever ate was a fish stick,” Simpson says, adding that she also loved chips, guacamole and queso. “Now I’m trying to eat fish.”
She adds, “I definitely don’t pick up the magazines. I definitely don’t Google my name. I try to avoid it completely. But I subconsciously know the talk is going on. Every day it’s a struggle for me. Weight Watchers is not intimidating. It’s not a diet. It’s a lifestyle.”
Simpson, who admits she “put on more baby weight than I was planning,” isn’t ashamed of her former body.
“I have to separate myself from the world’s expectations,” she says. “I have to look inside myself. I want to be a role model.”
