Trusted Infertility Care in Singapore

Devoted to Helping Couples Build Their Families for Over 20 Years

A normal fertile couple in their mid-20s having regular sex has a one in four chance of conceiving each month. This means that around nine out of ten couples trying for a baby will conceive within a year. However, one in ten will not—and these couples are deemed either subfertile or infertile.

Infertility is usually defined by fertility specialists as the inability to conceive after at least one year of trying. Many infertile couples can be successfully helped by assisted-conception treatments.

Dr Ann Tan has dedicated her storied two-decade career to the subspecialty of infertility
and assisted reproduction treatments; and nothing gives her greater joy than to help couples complete their families.

Treating Infertility Requires Both Parties’ Involvement

Many people tend to have the misguided idea that infertility is mainly due to the woman. However, men actually account for around half of all infertility cases faced by couples. Having both partners get assessed, and be present to support each other through the often-emotional journey together, can go a long way.

Causes of Male Infertility
  • Low sperm count: Normally, men produce at least 15 million sperms per millilitre of semen (WHO 2010 criteria); fewer is judged to be subfertile.
  • Poor sperm motility: This results in sperms being unable to swim through the cervix to meet the egg in the fallopian tube.
  • Abnormal shape (known as morphology), causing individual sperms to be unable to penetrate the outer layer of an egg.
  • Non-production of sperm (because of testicular failure)
  • Complete absence of sperm (perhaps because of an obstruction that causing male infertility e.g. absent vas deferens)
  • Excessive heat around the scrotum due to varicoceles or other lifestyle factors, leading to defective sperm production.
Causes of Female Infertility
  • Hormonal disorders: This may cause egg follicles to not grow within the ovary, or an egg might not be released, impacting ovulation.
  • Damaged or blocked fallopian tubes, which will prevent an egg and sperm meeting.
  • Endometriosis, in which womb tissue invades and damages neighbouring reproductive tissue.
  • Excessively thick cervical mucus, which prevents sperm from passing through
Women Fertility & Fetal Centre provides detailed couples’ fertility screenings so that you and your partner can receive the best possible care moving forward.

Assisted Conception

Assisted conception is not usually a first resort in the treatment of infertility. Other options such as optimising the timing of intercourse (to coincide with ovulation) may be tried first; as well as lifestyle and dietary changes to help couples to get into better health, which helps improve fertility.

Should there be other underlying medical conditions hindering natural fertilisation (e.g. blocked fallopian tubes), then assisted reproduction methods like IVF (in-vitro fertilisation) may be recommended.
