Hope has emerged for infertile men as scientists at Newcastle University have understood the importance of a gene in regulating the production of fully-functioning sperm.
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.
Studies have repeatedly linked maternal smoking during pregnancy with reduced sperm counts in male offspring.
Air quality has been associated with numerous adverse health outcomes from asthma to pre-term birth.
A recent study examined the relationship between endometriosis and infertility to determine effective fertility treatments.
Contrary to common suggestion, women are opting to freeze their eggs not to pursue education or careers but for reasons 'mostly revolving around women's lack of stable partnerships with men committed to marriage and parenting.
Doctors call it a chemical pregnancy because levels of the hormone human chorionic gonadotropin (hCG) are initially elevated enough to produce a positive result on a pregnancy test but dip again before a doctor can see the gestational sac on an ultrasound.
Scientists have discovered that some treatments for cancer and sickle cell disease can destroy the germ cells that go on to develop into sperm in the testes of young boys. In some pre-pubescent boys, the treatment for sickle cell disease results in complete destruction of all their germ cells, which are called spermatogonia.
It is known that in vitro fertilization (IVF) can affect the size of the newborns. Children derived from fresh embryo transfer have smaller birth weight, and surprisingly, children derived from frozen embryo transfer have subtly higher birth weight in average.
