Tubal Ligation

Tubal ligation is the most common method of sterilization. It involves severing and tying a woman’s fallopian tubes to prevent eggs from being fertilized by sperm.1 A similar procedure for men is a vasectomy, where a male’s testes are severed and tied.Although there have been accounts of sterilization being performed as far back as the 19th century in Europe, it was only in the 1960s – with the invention of the laparoscope – that surgery methods progressed far enough to allow consistently safe outcomes.3

Dilation and currettage

Dilation and curettage is a method where the cervix is dilated and a curette – a metal rod with a handle on one end and a sharp loop on the other – is used to scrape out the tissue in the uterus.1 The danger in such a procedure was that it could perforate the uterine or cause infection.2 This method is now uncommon in abortion. The more common technique today is vacuum or suction aspiration. This method was pioneered in 1958 in China.3 It involves inserting a sterile cannula connected to a pump into the vagina. The pump creates a vacuum that is used to empty uterine contents.4 It is safer than using a current, but there is still a risk of excessive blood loss or perforation of the uterine.5

Artificial Insemination of Animals

Artificial insemination of animals had been carried out decades before the technology was applied to humans. In Singapore, early cases dated back at least to 1938 when artificially inseminated cows were born in the Singapore Dairy Farm.This was not particularly controversial and indeed considered advantageous to the livestock industry as pedigree cows often did not breed well in Singapore’s tropical climate. Artificial insemination also helped owners of pedigreed dogs in Malaya produce puppies when their movements were restricted by anti-rabies regulations in the end of 1940s.2 Singapore, in fact, developed artificial techniques for reproducing animals to the extent that by 1968, super guppies were bred here for export.3

Test Tube Baby

Within the Muslim community in Singapore, there was little interest in artificial insemination until the birth of the first “test tube baby.” The baby, Samuel Lee Jian Wei, was born in 1983 at the Kandang Kerbau Hospital.1 The local papers covered the event quite extensively, touting his high technology birth.2 The interest in this particular baby could be attributed to a paradigm shift in reproductive technology. Before in-vitro fertilization, artificial insemination births refer only to conceptions done through injecting sperm into the vagina in order to increase gamete density at the site of fertilization so as to improve chances of conception.3 Test-tube babies born through in-vitro fertilization, on the other hand, took the process a step further by extracting the egg from the mother and sperm from the father for fertilization outside the womb. Samuel was the first test-tube baby conceived in this fashion and this was done five years after the first test-tube baby in the world – Louise Joy Brown – was born on 25 July 1978. Both babies grew up to be healthy, high-functioning adults.
