Baby boys who are born small for their gestational age are at increased risk of having fertility problems in adulthood, according to research published in Human Reproduction [1], one of the world’s leading reproductive medicine journals. Researchers in Denmark looked at 5594 men and 5342 women born between 1984 and 1987 and followed them through […]

Women with polycystic ovary syndrome face higher risk of breathing difficulties
Madrid, Spain: Women with polycystic ovary syndrome (PCOS) are more likely to develop poor respiratory health based on lung function tests, according to research presented at the European Respiratory Society International Congress. [1] PCOS affects how a woman’s ovaries work because of a hormone imbalance. It can cause irregular periods, infertility and variety of other […]
New study aims to show how to identify risk of recurrence of developmental disorder in future pregnancies
Gothenburg, Sweden: Having a child with a developmental disorder can cause parents to worry about the outcome of further pregnancies. In cases where the genetic mutation causing the disorder is not present in either parent it is assumed to be a one-off event with a very small chance of recurrence. But in some families, the […]
Non-invasive prenatal diagnosis for foetal sickle cell disease moves a step closer
Gothenburg, Sweden: Sickle cell disease (SCD) is a form of anaemia that is inherited when both parents are carriers of a mutation in the haemoglobin gene. Currently, it can only be diagnosed in pregnancy by carrying out an invasive test that has a small risk of miscarriage and is therefore sometimes declined by parents. Now, […]
Discovery of new genetic causes of male infertility will lead to better diagnosis and treatment
Gothenburg, Sweden: Infertility – the failure to conceive after a year of unprotected intercourse – affects one in every six couples worldwide, and the man is implicated in about half of these cases. Despite the known importance of genetic factors in the event of the man producing no sperm, only about 25% of these cases […]
Stress during early pregnancy is linked to reduced reproductive function in male offspring
Men whose mothers were exposed to stressful life events while they were in the first 18 weeks of pregnancy may have reduced sperm counts when they become adults, according to a study published in Human Reproduction [1], one of the world’s leading reproductive medicine journals. Research has shown that the first few months of pregnancy […]
Infertility is linked to small increased risk of cancer
A study of over 64,000 women of childbearing age in the USA has found that infertility is associated with a higher risk of developing cancer compared to a group of over three million women without fertility problems, although the absolute risk is very low at just 2%. As cancer is unusual in pre-menopausal women, the […]
Sperm quality unaffected by one course of chemotherapy for early testicular cancer
Men with early stage testicular cancer can safely receive one course of chemotherapy or radiotherapy after surgery without it having a long-term effect on their sperm count, according to a study published in the leading cancer journal Annals of Oncology [1]. Although it is known already that several rounds of chemotherapy or high doses of […]
Unexpected results suggest a few joints may not harm men’s sperm. Researchers urge caution and call for more research on effects of cannabis on reproductive health
Researchers investigating the effect of cannabis smoking on men’s testicular function have made the unexpected discovery that it is linked to higher sperm counts and higher testosterone levels among moderate users compared to men who never smoked it. The study is published in Human Reproduction [1], one of the world’s leading reproductive medicine journals. Previous […]
No overall increased risk of cancer in children born after fertility treatment
Children born after assisted reproductive technology (ART) do not appear to be at greater risk of developing cancer than other children, according to the first study to look at the long-term cancer risk in ART children compared to those in the general population or who were naturally conceived by subfertile women. The study of 47,690 […]
