From Conceiving to Delivering


Having a baby is truly remarkable. From mutual love that creates new life, to the very first kick in your belly and ultimately to the climacteric birth of your baby, the journey is nothing short of a miracle. While your joy is immense, it is only natural to have concerns at any point during this life changing experience. For instance, you may be anxious to conceive, or could be apprehensive about childbirth.

Difficulty in conceiving: Are there simpler treatments before IVF?

As a woman ages, her chances of conceiving are slimmer, particularly above the age of 35. For women, the common causes of infertility include: ovulation problems, blocked or unhealthy fallopian tubes and endometriosis. For men, absent, insufficient or defective sperms due to hormonal and genetic disorders, heavy smoking, varicocoele and infections may also hamper fertility. Treatment would involve resolving the abnormalities and individualizing therapies to obtain the simplest, cheapest and safest modality with reasonable success. Options would include:

1. Better understanding of the fertile period

Knowledge and timing of the fertile period is essential, coupled with frequent sexual intercourse. Timed sex with ovulation – predicted from urine tests and a good menstrual calendar – may improve conception rates.

2. Treating underlying hormonal disorders

80—90% of women achieve ovulation once hormonal abnormalities are corrected, increasing the chance of conception. This can be achieved with fertility drugs ranging from oral medications to injections to boost ovulation.

3. Intrauterine insemination

Chances of conception can be further improved with intrauterine insemination in cases where there is mild sperm defect. This is a simple procedure where washed sperms are flushed into the womb at the time of ovulation.

4. Corrective surgery

Depending on the damage to the fallopian tubes, tubal surgery may be helpful. Success of pregnancy following tubal surgery is variable. Compared to IVF, surgery is a one time treatment with a higher potential for long term fertility. Surgery in endometriosis improves fertility rates but not back to normal levels.

5. IVF

Simpler options should be considered first before IVF but it may be needed for severely damaged fallopian tubes, significant endometriosis and considerable sperm abnormalities. Concerns surrounding IVF include cost, psychological, emotional and physical stress, higher risk of multiple pregnancies and premature birth. Successful conception hinges on a myriad of factors concerning both partners. Do seek medical consultation if you and your partner are unable to conceive after having regular, frequent, unprotected sex for a year.

Is my baby normal?

With increasing educational and socio—economic status, there is a trend towards deferred child bearing. The problems associated with late motherhood pregnancy include maternal and fetal problems.

Firstly there is an increased risk of miscarriage. There is also an increased risk of chromosomal abnormalities. The most common chromosomal abnormality is Down’s syndrome, which can be screened for in all pregnant women.

This screening test can be done between 11 —13+ weeks of pregnancy via a blood test and ultrasound scan to measure the neck fold thickness and looking for the nasal bone. It does not carry any risks to the fetus. This allow mothers the time to make an early choice about the pregnancy should an abnormality be detected. Confirmatory tests for Down’s syndrome include amniocentesis which can be performed between 16—20 weeks gestation or the chorionic villus sampling which can be performed from the 11th week. Both confirmatory tests however are associated with a small risk of miscarriage.

Medical conditions like gestational diabetes and hypertension are more common in older mothers. Older mothers may also tend to have more problems in labour. Although childbearing at an advanced maternal age is associated with higher risks to the pregnancy, these risks can be managed with close surveillance during the pregnancy and during the labour period to reduce potential complications.
