Route to Parenthood
Boosting your chances of pregnancy
Did you know that humans are among the least fertile species on earth? For some couples,
conceiving a child is relatively simple. However, that does not apply to everyone.
Conception difficulties are more common than you would imagine.
Age does play a role in the reproductive
game. The ideal age for conception for
women is between 22 and 26 years of
age. For every year after 30 years old,
the chances of conception decline by
2.5% and this drastically declines after 40
years of age.
Statisticians have estimated that the
chances of conceiving are about 10% per
month for a couple in their forties even
if tests do not detect any abnormalities.
The American Society of Reproductive
Medicine guidelines have shown that the
chances of conception at age 46 are less
than 1% even with In Vitro Fertilisation
(IVF).
If you haven’t conceived after 12 months
of trying, (or six months if you’re 35 years
or more), it may be time to consider
seeking medical advice. You should seek
advice earlier if you are on long term
medication for a medical condition such
as thyroid disorder, diabetes, depression
or autoimmune disorders.
About one in ten couples experience
difficulties conceiving. Fertility treatment
can bring you a step closer to your
dreams of having a child. There are many
different treatment options available.
They include:
1. Lifestyle modification
“The most important correctable
factors for fertility are weight control,
abstinence from smoking and alcohol
for both husband and wife, and
optimisation of the female pelvic organs
through the removal of cysts, fibroids,
scars (adhesions) and damaged
fallopian tubes,” said Dr Sheila Loh,
Specialist in Obstetrics & Gynaecology
at Raffles Women Centre.
Body mass index below 18 and above
25 may be associated with ovulatory
disorders in women. Obese men
may also have poorer sperm mobility.
If you’re a smoker, it’s time to stop.
Smoking causes accelerated ageing of
a woman’s eggs and if the husband also
smokes, chances of conception in an
IVF cycle would be significantly lower
as compared to non-smokers.
2. Reproductive surgery
There are a variety of structural
causes of female factor infertility that
have surgical solutions. For example,
reproductive surgery and diagnostic
procedures can correct tubal
obstruction, endometriosis, uterine
fibroids, and scarring from pelvic
inflammatory disease.
3. Medications to induce ovulation
Examples include Clomiphene,
Metformin and Gonadotrophins.
According to Dr Koh Gim Hwee,
Specialist in Obstetrics & Gynaecology
at Raffles Women Centre, Clomid
(Clomiphene Citrate) is the most
common and most useful drug for
treatment of ovulation problems in
women. However, it is not useful for
women who are already ovulating
and when the infertility is related
to other problems. Clomid is safe
provided its use is monitored because
some women do develop cysts after
taking Clomid. “The cysts are usually
benign and the result of an underlying
problem of the ovary. It is not directly
due to the medication itself,” Dr Koh
added.
4. Artificial insemination or IUI
The purpose of the Intra Uterine
Insemination (IUI) programme is to
place some of the good quality sperms
into the uterus at the time the wife
releases her eggs. Hence, to ensure
optimum chances at IUI, the woman
must have a normal uterus and patent
fallopian tubes. Her husband’s sperms
must also be of sufficient quality and
quantity.
“Chances are also higher if she
is below 37 years of age and the
treatment is performed together with
super-ovulation, i.e. medications to
induce more than one egg,” said
Dr Loh. Average success rate is about
12-15% per attempt.
5. IVF
IVF is the general term covering all
the various programmes that involve
the help of a scientist to fertilise the
eggs in the laboratory.
A couple needs this treatment if they
have blocked or damaged fallopian
tubes, severe endometriosis or if the
doctor suspects a fertilisation problem
e.g. older women, women with
fewer eggs or failed IUI treatment. This treatment is also suitable if the
husband has poor sperm quality.
IVF outcome is most dependant on
the egg quality. Dr Loh stressed that
although IVF has a much higher success
rate, at an average of 30-40% per
attempt, this must be weighed against
its risks - more injections, more stress,
higher complication rate of multiple
pregnancy and ovarian hyperstimulation
syndrome (where the woman gets verybloated with water retention and in rare
situations, breathlessness). IVF is also a
more lengthy and expensive treatment
when compared to IUI.
IVF is used for severe infertility factors
or as a last resort if simpler treatments
fail. HN
Male Infertility
Studies have shown that male
infertility is on the increase because of
declining sperm quality and counts. According to Dr Fong Yan Kit, Specialist
in Urology at Raffles Surgery Centre,
factors that can affect sperm health
include:
a. Varicocele (an abnormal enlargement
of the veins in the scrotum draining
the testicles) as it elevates the intrascrotal
temperature
b. Drugs, smoking and alcohol
c. Previous infection of the testis and
prostate
d. Exposure to strong radiation
e. Stress
Even if you are facing male fertility
issues, all hope is not lost.
Dr Thong Pao Wen, Specialist in
Obstetrics & Gynaecology at Raffles
Women Centre, shares with us the
following ways to improve their sperm
quality:
a. Stop smoking
b. Take a regular supplement containing
essential vitamins, minerals and
anti-oxidants
c. Prevent overheating of the scrotum by
avoiding tight underwear or long
stays in the sauna
d. Avoid excessive pressure on the
scrotum (e.g. long distance cycling).
e. Learn to relax and prevent excessive
stress. Eat well and sleep well
f. Maintain a healthy weight as being
over or under-weight can influence
estrogen and testosterone levels
g. Stop using recreational drugs and
alcohol
h. Stop using body building anabolic
steroids as it can cause testicular
shrinkage
i. Avoid over intensive exercise which
can cause a testosterone
deficiency
j. Avoid environmental hazards like
radiation, pesticides, heavy metals,
lead or paint
