Taurine deficiency in sperm linked to male infertility

Taurine deficiency in sperm linked to male infertility

A recent study published in the Federation of European Biochemical Societies has uncovered a key role in regulating the morphology and fertility of sperm cells.

Japanese scientists have discovered that sperm with taurine deficiency, an amino acid found in beef, lamb, eggs and most dairy products had reduced morphology and were more likely to become infertile. The taurine helps to prevent large changes in the shape of the sperm due to an influx or efflux of water into the cell and is pivotal for male fertility.

The research revealed that the shape and structure of the sperm relied on the presence of taurine had once the sperm were in the genital tract. Without sufficient taurine, sperm are more than twice as likely to develop tail defects, which stops them from being able to move towards the egg.

Interestingly, the scientists also discovered that when the sperm cells were supplied with extra taurine, the tail defect disappeared, and the sperm were able to swim normally.

Taurine rich foods consist of meat, fish, shellfish, eggs and dairy products, so vegans and vegetarians are scientifically believed to be at higher risk of taurine deficiency.

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.
