The Influence of the Pelvic Floor Muscle Massage on Pregnancy Outcome in Patients Treated with Frozen-Thawed Embryo Transfer

Abstract

Objective: To research the influence of the pelvic floor muscle massage on pregnancy outcome of patients treated with frozen-thawed embryo transfer (FET).

Methods: We choose 120 patients who will have the frozen-thawed embryo transfer after it is unfreezed, and they are departed into two groups averagely, 60 of observation group and 60 of control group. Both groups start taking estradiol valerate twice a day on the third day of the menstrual cycle, 3mg one time. 14 days later, all patients need to inject progesterone except taking estradiol valerate. The observation group: Starting the pelvic floor muscle massage from the end of menstruation till the day of injecting progesterone, 15-20 minutes, 50 HZ, the acupoints are huiyin and baliao. The contrast group doesn’t have any other therapeutic measures. We will transfer the high-quality embryo on the suitable day. We contrast the basic conditions, the embryo, the endometrial thickness and types of uterine endometrium. To analyze the endometrial blood type, PI, RI, S/D, biochemical pregnancy rate, clinical pregnancy rate and early abortion rate. 

Results: There are no statistical result in transferring conditions, the endometrial thickness and types of uterine endometrium. After the treatment, we find that：1. in the observation group ，after the treatment of pelvic floor muscle massage ,the endometrial blood of the menstrual 17th day compared with the menstrual 9th day, type Ⅰ decreases clearly, type Ⅱ and Ⅲ increase evidently(p<0.05);2. in the observation group ，after the treatment of pelvic floor muscle massage , we get that the indexes RI, PI and S/D of the menstrual 17th day compared with the menstrual 9th day , reduced remarkably(p<0.05);3 the observation group of patients after treatment, the menstrual 17th day endometrial blood flow decreased significantly than control group in blood flow Ⅰ type, type Ⅱ + Ⅲ increased significantly,(p < 0.05) ;4. The observation group of patients after treatment, PI, RI and S/D of the menstrual 17th days was lower than control group significantly (P < 0.05);5. in the observation group of patients after treatment ,the endometrial thickness compared with the control group was no statistically different (p>0.05), but the endometrial thickness of the observation group was higher than the control group;6.the implantation rate and clinical pregnancy rate are higher in the observation group than those in the control group.

Conclusion: The pelvic floor muscle massage improves the endometrial thickness and endometrial blood conditions, so as to increase the clinical pregnancy rate of patients with frozen-thawed embryo transfer (FET).
