Why do embryos fail to implant?

When it comes to the embryo, the health of the sperm and egg even before fertilisation play an important role in embryo growth and development as well as the genetic factor.

Lifestyle factors such as smoking and drug use can influence the quality of sperm and egg, so that even if they create a genetically normal embryo, it may not be healthy enough to implant.

Uterine factors can also play a role in implantation failure. Intrauterine fibroids, lesions or polyps can affect the implantation of a healthy embryo and result in recurrent implantation failure.

There are many possible reasons why an embryo may fail to implant, however for some patients, the cause may never be known, which is why research and development into reproductive technology is incredibly important, to help increase implantation potential and to help provide answers for patients who are having trouble conceiving.

FAQs about improving natural fertility

Will stress affect my ability to get pregnant?

Yes, chronic stress can impact fertility by disrupting hormonal balance and ovulation patterns. Managing stress through relaxation techniques, regular exercise, adequate sleep, and mindfulness practices may help optimise your chances of conception. Consider speaking with a counsellor if stress feels overwhelming.

How does my partner's health affect our fertility?

Sperm health accounts for about 40% of conception challenges. Your partner can improve sperm health by maintaining a healthy weight, avoiding excessive heat exposure (hot tubs, saunas, tight clothing), limiting alcohol, quitting smoking, managing stress, and taking a multivitamin with antioxidants. Sperm takes about 3 months to develop, so lifestyle changes need time to show results.

When during my cycle am I most fertile?

Your fertile window typically spans 5-6 days, ending on ovulation day. For a regular 28-day cycle, this usually falls between days 10-15, with peak fertility 1-2 days before ovulation. Track your cycle using ovulation predictor kits, basal body temperature, or cervical mucus changes to identify your unique pattern. Having intercourse every 1-2 days during this window optimises your chances.
