While in women younger than 45, the implantation rate is 45% on average, it drops to 35% in women from the 45-50 age group. Subsequently, the miscarriage rates increase with age in spite of using donor eggs: while they are less than 10% when the woman is 45 or less, they stand at 16% on average for women over 45. As explained above, a decline in endometrial receptivity is usually the reason behind this.
