取卵后通常会使用孕酮来帮助提高着床成功率。每个生殖医学中心会根据自己的观念和经验来制定治疗方案。例如，有些诊所会要求移植后卧床休息1-2天，而有些诊所却认为这没什么用。有些诊所推荐针灸治疗，而有些诊所则会开类固醇药物（如强的松）。在所有的这些方法中，孕酮是临床验证最有效的方法。当然，影响胚胎着床的另一个重要因素就是胚胎自身的质量。超过38岁的女性，她们卵子的染色体异常概率很高，这也是为什么这个年龄段的女性不容易着床或容易流产。
Progesterone is frequently prescribed after the egg collection to help increase the implantation rate. Each clinic has its own protocols that they ask patients to follow as based upon the treatment philosophy of the fertility center. Some clinics recommend bed rest for 1-2 days after the embryo transfer, whereas other clinics have not found this to be helpful. Some clinics recommend acupuncture and some will prescribe antibiotics and/or steroids like prednisone. Of all of these methods, progesterone use is likely the most proven scientifically to be useful. Of course, the most important factor that influences the implantation rate of the embryo is the quality of the embryo and whether it has normal chromosomes. Many embryos of women over 38 are genetically abnormal, which may explain why they do not implant or they lead to a miscarriage.
