Which is better: fresh or frozen embryo transfers?

When it comes to embryo transfers, which is better: fresh or frozen?

Many other fertility clinics have adopted the practice of routine freeze-all cycles, rather than transferring a fresh embryo, with the belief that it will improve the pregnancy outcomes.

This is, in fact, not the case. Recent research has shown that the use of frozen embryos over the use of fresh does not increase the chances of a successful pregnancy, in fact published data has shown there is no significant difference.

The study that was published in the British Medical Journal this month analysed the cycles of almost 500 patients who underwent IVF treatment, and found that there was no significant difference between the percentage of women who fell pregnant in the frozen embryo group compared to the women who underwent a fresh embryo transfer.

Opting for a freeze-all cycle still remains a perfectly safe alternative for women undergoing ART when there is a risk of ovarian hyperstimulation syndrome (OHSS), and this study should provide some peace of mind to patients who are faced with this situation.

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.
