We focus on our own bodies so much on TTCAL: charting, Vitex, cervical fluid…well, what about that OTHER oh-so-important fluid that is needed for babymaking? Yes, I’m talking SPERM.
Below is an article from Just Mommies all about those little swimmers.
When it comes to making babies, both the quantity and quality of sperm your partner produces matters. An average ejaculation contains about 180 million sperm (about 66 million per ml). When semen is analyzed doctors look at more than just how much semen is ejaculated. The amount of semen produced per ejaculation can vary quite a bit, anywhere from 1-6 ml of semen per ejaculation is considered normal. Likewise, the amount of sperm produced during an ejaculation can vary greatly. The quantity of sperm in a semen sample – or sperm count – is measured per ml; 20-150 million sperm per ml is considered normal. A sperm count below 20 million per ml indicates a low sperm count and could result in infertility.
While your guy may produce millions of sperm during an ejaculation only a handful of them – about 200 sperm – are hardy enough to make it past the cervix and travel far enough up the fallopian tube to fertilize the egg. With this in mind, let’s take a closer look at some things that can affect a man’s sperm.
Some basic info about sperm:
* Sperm are produced in the man’s testes, mature in the epididymis, and finally travel through the vas deferens and out through the urethra during an ejaculation. This process takes about 75 days.
* Sperm makes up only a small percentage of what is ejaculated.
* Healthy sperm can live up to 5 days inside the woman’s vagina.
* 20 million sperm per ml (or higher) of semen is considered normal.
* Some abnormal sperm are usually found in most semen samples. As long as 40% or more are shaped correctly, this is considered normal.
* They don’t call sperm swimmers for no reason. A normal sperm moves in a forward direction. A man is most likely fertile if at least half of his sperm are forward moving “swimmers”.
Things that can affect a man’s sperm
You probably know about some of the biggies like smoking, alcohol, illicit drug use or hot tubs impairing a man’s fertility but here are a few things you may not know about:
1. Morning sex = higher sperm count: If you are trying to conceive, time intercourse when his sperm count is at its highest. Researchers have found that men generally have a higher sperm count in the mornings. Men’s sexual interest may be higher in the mornings as well.
2. His weight matters: Women are not the only ones who have weight related fertility issues. Men who are overweight or underweight are more likely to have problems with infertility. Having too much or too little body fat may affect a man’s hormone levels. Scientists in one Finnish study found that a 20 lb weight gain may increase a man’s chance of being infertile by 10 percent.
3. Have more sex, not less: Men with low sperm counts are often advised to abstain from sex in order to improve their sperm count, but new research suggests that while this may improve sperm count, too much abstinence can damage the DNA of the sperm that is produced. Australian researchers have found that having daily sex actually improves the quality, if not the quantity of sperm. The thought behind this is that regular ejaculations get rid of the old sperm and make way for newer healthier sperm.
4. Folic acid: Not only good for the goose, but it is also good for the gander. Most women know that taking a folic acid supplement is important during childbearing years because it can prevent certain birth defects. You may not have known that it is also important for men to eat a diet containing folic acid. A recent study by researchers at the University of California, Berkley found that men who had lower levels of folic acid (or folate) in their diets had a higher rate of chromosomal abnormalities in their sperm.
5. Avoid soy products: A recent study published by Oxford University Press’s online publication Human Reproduction, suggests that eating a diet high in soy foods could cause men to have a lower sperm count. According to the study, men who ate soy foods were more likely to have lower sperm counts (although not necessarily abnormally low) than men who did not eat soy.
6. Skip the lubricants: Lubricants can impede the movement of sperm. A woman’s cervical mucous is designed to help transport sperm, but many commercial lubricants have the opposite effect. Lubricants like KY Jelly, baby oil, or petroleum jelly have been shown to slow down or damage sperm. Saliva can also damage sperm. One lubricant that is okay to use is Pre-seed. According to one study in the ASRM’s journal of Fertility and Sterility, Pre-seed was not shown to harm or slow down sperm.
7. Watch out for cell phones and lap tops: There have been a few studies that have shown that excessive use of lap tops or cell phones can cause sperm damage. Lap tops, if placed on a man’s lap, get hot over time. The increase in scrotal temperature may have a negative effect on a man’s sperm if he keeps a lap top sitting on his lap for extended periods of time. Similarly, cell phone emissions might also cause sperm damage. Keeping a cell phone in a close proximity to a man’s scrotum could potentially cause a decrease in sperm quality, according to a small research study from the Cleveland Clinic.
