Can IVF be used to select embryos with specific traits, such as skin colour?

It is not unusual to have some episodes of vaginal spotting when using the progestogen(Crinone) inserts. They can dry the vaginal skin and cause superficial abrasions which bleed when the pessary is inserted. In addition, some centres also use low-dose aspirin as a supplementary drug to enhance blood flow to the endometrium. These have the effect of thinning the blood and cause minor bleeds which seem to be worse then they actually are. The vaginal bleeds are not necessarily a sign of failed implantation.

I personally believe that the success of IVF is directly dependent on the health of the Woman and her husband. Eating well, as in eating nutrient rich foods helps to ensure proper cell function at every level. Minimising toxic chemicals, quitting smoking and not consuming contaminated foods and drinks helps reduce cell damage. I also believe that complementary Medicine such as those offered by TCM and acupuncture contribute positively to a successful outcome. I am loathe to quote results because it really depends on the medical reasons for doing IVF.
