Household Chemicals Harm Sperm in Both Men and Dogs

Common Household Chemicals Harm Sperm in Both Men and Dogs

Two chemicals found in household products and food could harm male fertility in both dogs and people, U.K. researchers say.

The chemicals are the plasticizer DEHP — used in products such as carpets, flooring, upholstery, clothes, wires and toys — and the industrial chemical polychlorinated biphenyl 153 (PCB153). Even though it is banned worldwide, PCB153 is still widely present in the environment, including food.

For this study, researchers from the University of Nottingham conducted laboratory tests with sperm from men and dogs. Their tests revealed that levels of the two chemicals consistent with environmental exposure had the same damaging effects on sperm in both species — reduced sperm motility and increased fragmentation of DNA.

Previous studies have reported a 50 percent decline in human sperm quality worldwide in the past 80 years. Another study by the same U.K. team found a similar decline in domestic dogs, pointing to the possibility that chemicals present in the home could be a factor.

“This new study supports our theory that the domestic dog is indeed a ‘sentinel’ or mirror for human male reproductive decline, and our findings suggest that man-made chemicals that have been widely used in the home and working environment may be responsible for the fall in sperm quality reported in both man and dog that share the same environment,” study leader Richard Lea said in a university news release.

Lea is an associate professor and reader in reproductive biology at Nottingham’s School of Veterinary Medicine and Science.

“Our previous study in dogs showed that the chemical pollutants found in the sperm of adult dogs, and in some pet foods, had a detrimental effect on sperm function at the concentrations previously found in the male reproductive tract,” he said.

Lea added that the new study is the first to test the effect of DEHP and PCB153 on both dog and human sperm in the lab, in the same concentrations found in real life.

Gary England is dean of the university’s School of Veterinary Medicine and Science.

“Since environmental pollutants largely reflect a Western way of life such as the effects of industry, the chemicals present in the environment are likely to depend on the location,” he said in the news release. “An important area of future study is to determine how the region in which we live may effect sperm quality in both man and dog.”

Sperm Benefits During Pregnancy

Sperm Benefits During Pregnancy

Benefits of Sperm During Pregnancy

 

  1. Actual Nourishment

 

There are numerous vitamins, minerals, and even a dose of protein in every ejaculation. While this won’t take the place of your prenatal vitamins, anything helps. If anything, the nourishment in sperm will keep your vaginal tissues healthy and get the cells ready for repair after delivery.

  1. Good Sleep

 

Semen has some melatonin in it that may be absorbed through your vagina and enter your bloodstream. This may help with those sleepless nights, a common side-effect of pregnancy. If your doctor gives the okay, sex every night before bed may be the best sleep remedy you’ve ever had. No pun intended.

 

  1. Getting Your Cervix Ready

 

One of the benefits of sperm during pregnancy is that it helps get your cervix ready for the big day. Semen or sperm contains high levels of prostaglandins. Prostaglandins soften the cervix to help it open up easier when labor begins. The prostaglandins may also help trigger contractions, so ask your doctor if sex is okay at the end of pregnancy.

 

  1. Feeling Better About Yourself

 

Some women may not find pregnancy a very sexy time of their lives. Weight gain, fatigue, and changing looks may cause a lowered self-esteem. Semen may contain chemicals that when absorbed through the vaginal walls, may decrease depression. Levels of these “feel good” chemicals have been found in women’s blood at increased levels for a few days after sexual intercourse.

 

  1. Immune System Protection

 

Another one of the benefits of sperm during pregnancy is immune system protection. Sperm contains proteins that may help strengthen your immune system. It may help prevent interactions between mom and baby, reduce the risk of pre-eclampsia in pregnancy, and keep you healthy. One reason being studied is that pre-eclampsia may be a DNA incompatibility between mom and dad. Sexual intercourse with baby daddy may help desensitize the immune system to dad’s DNA.

 

Safe Tips for Better Sex During Pregnancy

 

Don’t force things. Your desire for intimacy may wax and wane over the months. Let your partner know how you are feeling. Your body knows just when the right time is, listen closely. Be gentle and take things slow.

You may need to use a safe water based lubricant for comfort. Sex drive may be less in the end of pregnancy. While sperm is helpful then, you may need some help to get things started.

Make time for intimacy. Sperm is healthy for your pregnancy, but you need to have sexual intercourse to reap the benefits. Busy schedules, morning sickness (makes mornings a bad time), work, and other kids can all get in the way. Try going off to bed soon after dinner before you get too tired.

You may have to adjust positions. If you are making love for the benefits of sperm at the end of pregnancy, you may need to try different positions for the most comfort.

If you have oral sex, never let your partner blow air into your vagina. This is very seriously dangerous and can be life threatening. The air can form an embolism in your bloodstream and block a blood vessel.

Refrain from sexual intercourse if your water has broken already. This may mean your contractions have already started and you won’t need the benefit of semen to get things going, they already are. Intercourse could put you and your baby at risk for infection.

If the benefits of sperm during pregnancy are contraindicated due to a high risk pregnancy, you can ask your doctor about sex with a condom. Just keep in mind that even orgasms can be detrimental if you are at risk for miscarriage.

If you cannot have sex during your pregnancy, find other ways to be intimate. You can cuddle and watch movies, spend time reading together, or go for a walk every evening after dinner (as long as you aren’t on bedrest).

Last but not least, communicate with your partner. He may be feeling like “sex may hurt the baby,” or that “his sperm may get into your uterus,” all of which are old wives tales. Your baby will never know or be hurt by your lovemaking. The uterus is sealed off by the mucous plug and nothing gets past it until it dislodges at the end of your pregnancy. The baby is also cushioned by amniotic fluid, protecting him or her from any “bumps.” Explaining these things will help make your partner feel better about sex while you’re pregnant.
