Assisted reproduction: new research

Dexeus Mujer promotes research to improve infertility options Female infertility can have a number of causes: the woman may have reached the age of 40 (or be much older), they may have a low ovarian reserve, be in early menopause or have a poor response to hormonal stimulation treatments. As women, are we going about planning motherhood the wrong way? It isn’t so much a planning issue as it is a lack of information. Egg quality starts to plummet after age 36. What does ‘ovarian reserve’ mean? This term refers to the number and quality of antral follicles in...

When is the best time to become a mother?

Becoming a father at 50: what’s the biological limit for men?

Due to their ability to continue producing new sperm, men remain fertile for longer than women. However, studies show that the sperm produced by men around the age of 60 does not have the same fertility potential as that of a 25-year-old, because from the age of 45 onward, the potential for fertilisation and conception through intercourse is reduced. So how does ageing affect male fertility? For starters, it has been shown to affect the production of hormones and sperm, and while there is still much to investigate, available data and results show that as with any other cell in the body, the...
