A recent study published in Human Reproduction found that women who consume more fast food and less fruit take longer to become pregnant. The research, which analyzed data from over 5,500 women, suggests that a diet rich in fruits and low in fast food can improve fertility and reduce the time it takes to get pregnant.
A study by researchers at the University of Adelaide found that women who eat less fruit and more fast food take longer to get pregnant. The study also showed that a diet rich in fruits can improve fertility and reduce the time it takes for women to conceive.

The study found nearly twice as many women with unexplained infertility had elevated TSH levels compared to those with known infertility causes.
A new study by Lancaster University reveals that marginalized groups are often excluded from fertility data due to biases in survey design and sampling. This exclusion can lead to unequal access to reproductive healthcare and misguided policies.
A new study led by researchers at the University of Pennsylvania School of Medicine found that vitamin D deficiency may be a key factor for pregnant women with polycystic ovary syndrome (PCOS) getting pregnant. The research revealed that women with PCOS who were vitamin D deficient had a 40% lower chance of achieving a pregnancy compar...
Women with a history of infertility have a 10% increased risk of death compared to those without reported infertility struggles. Infertility is also linked to an increased risk of breast cancer and diabetes mortality, highlighting the need for further research into the long-term effects of infertility on women's health.
A new law in Rhode Island requires coverage for fertility preservation prior to gonadotoxic medical therapy. The authors of the perspective published in NEJM recommend revising existing non-infertility-related mandates or establishing a separate definition for fertility preservation, which could encourage other states to follow suit.

The study, which followed couples for 16 years, revealed that the majority of couples had children with their baseline partners and around one-fifth ended up separated or divorced.
A study has shown that an inexpensive fertility drug can be just as effective as more recent reproductive hormones in treating unexplained infertility. The 50-year-old drug, taken orally, was found to have a comparable pregnancy rate to newer hormones used in intrauterine insemination (IUI) with ovarian stimulation.
A new study found that long-term exposure to noise above 55 dB, equivalent to a suburban street, is significantly linked to male infertility. The researchers analyzed data from 206,492 men and found that those exposed to higher levels of noise had a greater chance of being diagnosed with infertility.

Fertility preservation for girls and young women with cancer is hindered by lack of awareness and funding. Despite guidelines, access to treatment is restricted due to variable oncologist awareness and conflicting funding policies.
A recent survey found that men generally lack awareness of risk factors contributing to male infertility, with only about 50% identifying potential dangers. This lack of knowledge can lead to devastating psychological impact and stress on relationships, emphasizing the need for public education to promote reproductive health among men.
Researchers are developing a system using phase-contrast imaging and mathematical analysis to identify the best-fitting sperm, leading to improved fertility treatment decisions. This new approach aims to reduce distress and expense associated with infertility treatments like IVF.

The results suggest resveratrol may be a promising treatment for PCOS and related metabolic problems.
The study found that ICSI men had almost half the sperm concentration and a two-fold lower total sperm count compared to naturally conceived men. They were also nearly three times more likely to have sperm concentrations below 15 million per millilitre of semen.
A $440,000 NIH grant is supporting a 3-year study examining the impact of cigarette smoke and genetic factors on female fertility. The researchers will assess ovarian reserve, in vitro fertilization success rates, and NAT2 genotype to better understand the relationship between smoking, genetics, and infertility.
A new study reveals that 43% of women with unexplained infertility are infected with the HHV-6A virus, which activates immune cells and produces cytokines making it harder for a fertilized egg to implant. The finding could lead to treatments improving outcomes for infertile women.
A survey of 15,000 women and men in Britain found that nearly half who experienced infertility did not seek medical help. The study also found that those who sought help were more likely to have higher educational qualifications and better job prospects.
