​We debunk five myths about fertility health. Read to find out more!

Myth #1: I am unlikely to face fertility health issues as I am generally healthy  

Fact: There are underlying medical conditions which affect fertility health

For women, these include polycystic ovarian syndrome, endometriosis, blocked fallopian tubes or uterine fibroids. For men, these include abnormalities in their sperm's shape and movement, or low levels of sperm.

You may also have prior medical conditions (e.g. diabetes, kidney disease, thyroid disease, eating disorders, or cancer treatment) that may require you to be on medications that affect your fertility or are not be suitable to be taken during pregnancy.

In addition, being underweight, overweight or obese may cause ovulation- or sperm-related issues.

Myth #2: Only women's fertility declines with age

Fact: Fertility declines with age for both men and women.

For men, sperm quality deteriorates with age, which could reduce the chances of conception and increase potential risk of gene defects. For women, the best chance of conceiving is in their 20s, as fertility declines in their 30s, particularly after age 35, as the number and quality of eggs that remain in the ovaries decrease with age. 

Myth #3: My lifestyle choices will not affect chances of conceiving

Fact: Smoking and heavy alcohol consumption can affect fertility health

Lifestyle choices such as smoking and heavy alcohol consumption* can affect fertility health. Reduce alcohol consumption and avoid smoking before trying to conceive.

Myth #4: I can still get pregnant easily through Assisted Reproduction Technology (ART) treatments when I get older

Fact: Success rate decreases with age 

ART treatments are medical treatments and procedures that typically include intra-uterine insemination (IUI) as a first line treatment, followed by in-vitro fertilisation (IVF). The procedure consists of five to twelve sessions in total, with each treatment cycle spanning between two to five weeks. Women are typically given two weeks of hospitalisation leave after embryo implantation for recuperation. There may be consultation and counselling to review the couple's treatment progress, details on procedures, financing and expected costs.

According to the 2021 Marriage & Parenthood Survey, many are not aware that reproduction technology cannot compensate for age-related decline in fertility. Over 70% of married and single respondents have the misconception that ART treatments have very high success rates for women above age 40. While ART treatments increase the chances of conception, the success rate is still dependent on the age of the woman. As seen from the table below, the success rate of the ART treatment decreases quite significantly as the age of the woman increases.
