Zika Virus and Cytomegalovirus in the first trimester

Zika Virus and Cytomegalovirus in the first trimester

Human Cytomegalovirus (CMV) is the leading viral cause of congenital infection and debilitating birth defects including abnormally small heads and brains, neuromotor deficits and hearing and vision loss.

Although CMV infections in adults and children are mostly asymptomatic and harmless, the virus can be lethal to the developing foetus. Similarly, the Zika virus can cause severe birth defects including microcephaly and a spectrum of congenital malformations and is spread by mosquitoes.

A study presented at ESHRE this week has focused primarily on viral proteins in chorionic villi from first trimester placentas and found that both viruses target the cytotrophoblasts, and cells that prevent the spread of pathogens from mother to foetus. By crossing the uterine-placental barrier and targeting these cells, the viruses are able to infect the growing foetus, which ultimately results in severe birth defects.

These recent studies have provided a novel strategy to help strengthen the natural protection and reduce virus transmission at the uterine-placental interface.

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.
