timing – Winnie Wagtail

There are many fertility myths flying around as fact out there! When it comes down to it though, every woman is different and will find certain things work better for her and her partner than others. But so this article isn’t a total cop out; we’ve done some research on the “Top 5 Fertility Factors” according to The Fertility Site of Australia YourFertility and medical journals (references below)..

1. Age

There isn’t a nice way to put it, the older you are…statistically, the trickier it makes things. This is considered the single most important factor in conception.

Conceiving naturally (without the help of say, IVF) statistics say:

From age 32, the odds of conceiving naturally begin to decrease gradually (but significantly).
From age 35, natural conception decline speeds up
By age 40, fertility has been reduced by half (at 30, the chance of conceiving each month is approximately 20%. At 40 it’s approximately 5%)

Not to make it all about the female biological clock…and you do hear time and time again, “oh he can have kids whenever, women have the biological clock…”… it may seem that men do to. Research has found that:

The average time to pregnancy for men 25 and under is a little over 4.5 months. Men at 40 it’s around 2 years (if the woman is under 25).
For men over 45 years, there’s a five-fold increase in time to pregnancy.
For couples travelling down the IVF route, if the male partner is 41 or over, then your chance of not falling pregnant is 5 times higher than men younger than them.
The volume of a man’s semen and their motility- their ability to move towards the egg, decreases continually between the ages of 20 and 80.
Miscarriage is twice as high for women that are with partners over 45 (and they themselves are under 25).

2. Weight

Parents to be, both sides of the parenting partnership, to better your odds at fertility, you should be within a healthy weight range.

Diet and exercise, not only for personal health gain, but in shaping healthy lifestyle habits to share with your to-be-bubs is worth taking incredibly seriously! Check out the following links to help you assess where you sit health wise, and access to some good tips re food choices.

Conversely, being underweight makes falling pregnant tricky too!

3. Smoking

We all know smoking is bad, so it shouldn’t come as a surprise that it’s not crash hot for fertility, either! Smokers may be at twice the risk of infertility than non-smokers and are 1.5 times more likely to take more than a year to conceive. Partners that smoke may also contribute to infertility.

Something I hadn’t considered was passive smoking and the effect is has on fertility. Research shows that actively smoking is only marginally worse than passive smoking, when it comes to fertility. Female passive smokers are more likely to take over a year to fall pregnant than women from non-smoking houses.

QuitPacks are fabulous, and midwives are trained in helping mama’s and their family members make short term and long term goals to either cut back, or kick the habit altogether!

Keep in mind, smoking does affect your baby, in more ways than one. See here for more information.

4. Alcohol

In a nutshell, heavy drinking will reduce your chances of falling pregnant. Of course, once pregnant, because we are unable to gauge a safe amount of alcohol, to reduce chances of Fetal Alcohol Syndrome, it is recommended that women do not drink throughout pregnancy. Please speak further to your midwife or obstetrician if you have further questions regarding alcohol in pregnancy.

5. Timing

Rather than trying to reword this, I’m doing the sneaky, and borrowing all words from ‘The Women’s guide to Fertility and Timing’, from YourFertility. See below:

Pregnancy is technically only possible during the five days before ovulation through to the day of ovulation. These six days are the ‘fertile window’ in a woman’s cycle, and reflect the lifespan of sperm (5 days) and the lifespan of the ovum (24 hours).

If a woman has sex six or more days before she ovulates, the chance she will get pregnant is virtually zero. If she has sex five days before she ovulates, her probability of pregnancy is about 10%. The probability of pregnancy rises steadily until the two days before and including the day of ovulation.

At the end of the ‘fertile window’, the probability of pregnancy declines rapidly and by 12-24 hours after she ovulates, a woman is no longer able to get pregnant during that cycle.

For those women who are not aware of their ‘fertile window’ or when they ovulate, sexual intercourse is recommended every 2 to 3 days to help optimise their chance of conceiving.

***A couple of extra things – I get asked a stack of questions about certain foods, in particular Soy. There seems to be conflicting conclusions drawn on the relationship between soy and infertility in studies found online. I personally have an opinion, however want some cold hard evidence to back it up. I’m in and out of hospitals this week, so I will keep you posted after some discussions with colleagues.
