Fertility, IVF and Egg Donation
We know that chromosomal abnormalities in eggs are responsible for fertility problems – particularly when the woman is in her late 30s or 40s.
- An abnormal number of chromosomes is referred to as aneuploidy
- Aneuploidy causes the increased rate of miscarriage with aging
- Aneuploidy is responsible for most of the decline in fertility with advancing age (both with and without IVF)
In recent years research has shown the importance of a structure in the egg called the meiotic spindle. This spindle is involved with aligning chromosome pairs so proper division of pairs can occur during egg maturation.
- As women age they are more likely to have an abnormal spindle apparatus that does not efficiently line up chromosomes prior to division
- This causes a higher likelihood for an unbalanced chromosomal situation in the mature egg – and then in the embryo
A recently published study (referenced below) might help us to understand why some women have more chromosomally abnormal eggs at a given age. This study was performed in mice, but may well have relevance for human reproduction as well (in many ways we aren’t as different from mice as we might like). (continue reading…)
Age and female fertility and waiting to have babies
- A recent report on the average age at first childbirth from the CDC’s National Center for Health Statistics showed that as of 2006, women in the US waited an average of 3.6 years longer to have their first baby, as compared to 1970.
- There is not enough discussion in our society about the effect of age on fertility.
- Women’s liberation is a good thing and women have made very significant advances over the past 40 years. Many women are pursuing advanced education and careers.
- However, there is a potential “disconnect” involved. Women are waiting longer to have children – but many are not educated about what that delay can do to their fertility.
These days, many couples try to have their first child when the woman is in her mid-to-late 30s. Some will get pregnant easily, and others end up needing fertility treatments. (continue reading…)
