Immunisation Awareness for Pregnancy !

Under the National Immunisation Program, vaccines against influenza and pertussis (the virus which causes whooping cough) are offered to pregnant women at no cost. These vaccines are highly effective in reducing the impact of these infectious diseases on pregnant women and newborns.

Pregnant women are at high risk of becoming seriously ill with influenza which can result in premature delivery, low birthweight and death in young babies. Influenza vaccination can be given at any time during pregnancy, preferably before the flu season.

Meanwhile, pertussis remains common in Australia and babies less than six months of age are at greatest risk of severe disease and death from pertussis. Pertussis vaccination is ideally given between 28 and 32 weeks of pregnancy.

Given their significant benefits and safety profile, these vaccines are strongly recommended for pregnant women and can be given at your local immunisation centre or general practice.

Don’t lose track of your fertility time .

It is very easy to lose track of time when you are busy with career development, finding your soulmate and building your dream home. The female reproductive system does not provide unlimited egg supply and hence, delaying childbearing past 35 years of age has become the most common cause of fertility problem in modern times.

There is no effective treatment to create new eggs and it is therefore important that you have a plan for your future family.

We can provide a full assessment of your fertility potential and discuss suitable options to meet your needs including counselling, egg storage and fertility treatment.

So, when you see your doctor for your next medical check-up, don’t forget to mention about your fertility needs.

Acupuncture does not help improve IVF outcome - new study shows .

Acupuncture has been used as an alternative therapy for infertility and there have been claims that it could improve IVF outcome, i.e. pregnancy and livebirth rates. For a long time, there has been no high-quality trials substanting such claim and many women were merely embracing an alternative therapy with the hope it would improve their IVF success rates.

A four-year randomised trial of 824 women attending 16 IVF centres in Australia and New Zealand was conducted and found no difference in birth rates between women who received acupuncture and those given sham treatment (i.e. 18.3% versus 17.8%).

This is a landmark study confirming our long-standing belief that acupuncture effect on fertility and IVF outcome is only confined within the placebo effect and at best some stress relief.

We do not recommend the routine use of acupuncture for our patients seeking fertility treatment. And as far as our practice goes, the majority of our patients do not even need IVF treatment, and are still able to conceive and have a baby within 2 years.

New National Cervical Screening at a glance .

From 1 December 2017, the Australian government has launched the new cervical screening test which can improve detection for early cervical pre-cancerous changes, and make the test more convenient and acceptable to women. We fully support this new program and have confidence that our future in preventing cervical cancer is looking brighter than ever.

How does this change affect you?

Well, if you are already in the 2-yearly PAP smear screening program, you just need to see your doctor for this new test when your next PAP smear is due. If the result comes back as low risk for oncogenic HPV genotype, then your next screening test would be done every five years until you reach the age of 70-74. If the result comes back abnormal, your doctor will advise you on the next step which can be a repeat test in 6-12 months' time or a colposcopy assessment which we can do for you.

If you have never had a PAP smear done, then you should have this new test done as soon as convenient if you are aged 25-70, or if you have unusual vaginal discharge / bleeding. 

If you have had previous abnormal PAP smear, consult your doctor because you may need annual test done if your previous abnormal test put you at high risk of getting cervical cancer.
