6 Fertility Facts

If you’re trying to conceive and not falling pregnant, here is some information that may assist you:

When are you most fertile during your menstrual cycle?

6 days in each cycle; 5days before ovulation and day of ovulation.

When is the semen quality at its optimum level?

After two to three days of ejaculatory abstinence; longer intervals are associated with lower pregnancy rates.

Is orgasm during sexual intercourse necessary for conception occur?

No, it’s not necessary and neither does the position of how intercourse occurs affect the chance of conception.

Does the use of lubricant affect the chance of pregnancy?

There is no definite effect, but it is better to use oils base lubricant eg canola or olive oil.

Does my chance of falling pregnant decrease as I get older?

Yes most definitely. The number of eggs in the ovary declines over time, the quality of eggs also declines and eventually reaches a critical threshold below which pregnancy is no longer possible. The decline, on average, begins at age 35.

What is fertility preservation?

Fertility preservation is a method of preserving eggs and embryos that allows women to delay their childbearing time to a time that suits them best. This includes freezing eggs or embryos CRYOPRESERVATION OF OOCYTES and EMBRYO CRYOPRESERVATION

Iodine in pregnancy

It has been noted for many years that Iodine is an essential micronutrient in pregnancy.

Severe iodine deficiency in the mother can lead to cretinism and mental retardation in the newborn.

World Health Organiziation has listed maternal iodine deficiency as a main cause of newborn brain impairment worldwide. The developing fetus is dependent on the mother’s thyroid hormone production for its brain development which in turn is dictated by natural dietary intake or supplementation of iodine. It is likely that low levels of maternal iodine consumption, especially in early pregnancy are associated with poor brain performances in their offspring.

A study in England followed up the children of over 1000 women who had their urinary iodine levels tested in the first 12 weeks of pregnancy. The study found that the children’s verbal, reading and IQ scores related to the mother’s iodine levels during her early pregnancy stage. Poorer childhood performances were associated with lower iodine measurements. (Lancet 2013;382:331-7)

Therefore it is recommended that all pregnant women should receive sufficient iodine in their diets by eating seafood or by taking iodine supplement of 150µg-220µg per day

Seafood – dietitians recommend two to three meals of seafood per week to get the beneficial fish oils.

Eating fish twice a week will also provide most adults with enough iodine to fulfill their average iodine requirement.

Bread – is now made using iodised salt in Australia. Organic breads and ‘no added salt’ breads are the only exceptions to this rule.

Seaweed (kelp), dairy products and eggs – provide additional dietary sources of iodine.

Some vegetables – may contain iodine, but only if they are grown in iodine-rich soils.

IVF and Breast Cancer Risk

For many years, studies have linked oestrogen and progestogen hormones to the risk of breast cancer.

This association is complex and includes both endogenous and exogenous hormones.

Recently researchers have raised the question about risks of breast cancer with IVF treatment as there are significant hormone manipulation during an IVF cycle.

Through this study researchers tracked over 25,000 women with a mean age of 33 years who underwent ovarian stimulation as part of their IVF management and followed them over 20 years.

The results have shown that the incidences of breast cancer were the same for the IVF group as for those not receiving IVF.

From this study it appears that IVF hormonal treatments do not affect a woman’s risk of developing breast cancer.
