ABSTRACT
OBJECTIVE@#To observe the effects of acupoint catgut embedding on miscarriage prevention and pregnancy outcome in patients with threatened abortion after in vitro fertilization-embryo transfer (IVF-ET).@*METHODS@#Sixty cases of patients with threatened abortion after IVF-ET were randomly divided into an observation group and a control group, 30 cases in each group. The patients in the control group were treated with intramuscular injection of progesterone (40 mg) once every day, while the patients in the observation group, on the basis of the treatment of control group, were treated with catgut embedding at Geshu (BL 17), Ganshu (BL 18), Shenshu (BL 23), Pishu (BL 20), Weishu (BL 21), Xuehai (SP 10), Diji (SP 8) and Fuliu (KI 7), once every two weeks, six times as a course of treatment. The treatment was given until 12 weeks into pregnancy. The level of serum human chorionic gonadotropin (HCG), estradiol (E) and progesterone (P) before and after treatment was recorded; the TCM syndrome score before and after treatment was compared; the successful pregnancy rate and spontaneous abortion rate after treatment were observed in the two groups.@*RESULTS@#Compared before treatment, the scores of TCM syndrome in both groups were reduced after treatment (both <0.01), and score in the observation group was superior to that in the control group (<0.05). After treatment, the clinical efficacy in the observation group was superior to that in the control group (<0.05). After treatment, the hormone levels (β-HCG, E, P) in both groups were increased steadily; the hormone levels in 6-week pregnancy, 8-week pregnancy and 10-week pregnancy were significantly higher than those in 4-week pregnancy (all <0.05); except the levels of P and β-HCG in 10-week pregnancy, the hormone levels in the observation group were superior to those in the control group (all <0.05). After treatment, the early abortion rate was 16.7% (5/30) in the observation group, which was lower than 33.3% (10/30) in the control group (<0.01); the pregnancy rate was 96.0% (24/25) in the observation group, which was higher than 80.0% (16/20) in the control group (<0.01).@*CONCLUSION@#Acupoint catgut embedding is effective for preventing threatened abortion, which could significantly reduce the spontaneous abortion rate, improve the pregnancy success rate, regulate hormone levels in patients after IVF-ET.

<p><b>Objective</b>To investigate the pregnancy outcomes of assisted reproductive technology (ART) with cryopreserved donor sperm and the safety of the offspring thus conceived.</p><p><b>METHODS</b>The Human Sperm Bank of CITIC Xiangya Hospital provided cryopreserved donor semen to 31 reproductive centers in China between January 2006 and December 2012, with which 50247 ART cycles were accomplished. We compared the rates of birth defects and spontaneous abortion of intracervical insemination (ICI), intrauterine insemination (IUI), in vitro fertilization (IVF), and intracytoplasmic sperm injection (ICSI).</p><p><b>RESULTS</b>A total of 39 047 ART cycles were performed by artificial insemination with cryopreserved donor sperm, including 36 674 cycles of ICI and 2 372 cycles of IUI. Among the 8 612 clinical pregnancies achieved by ICI, there were 917 cases of spontaneous abortion (at <28 gestational wk) (10.6%) and 6133 live births, with 43 cases of birth defect (0.70%). Of the 547 clinical pregnancies achieved by IUI, there were 41 cases of spontaneous abortion (7.5%) and 426 live births, with 2 cases of birth defect (0.47%). Totally, 11 200 cycles of IVF and ICSI were accomplished with cryopreserved donor sperm. Of the 5 860 clinical pregnancies achieved by IVF, there were 456 cases of spontaneous abortion (7.8%) and 5089 live births, with 55 cases of birth defect (1.08%). Among the 350 clinical pregnancies achieved by ICSI, there were 30 cases of spontaneous abortion (8.6%) and 229 live births, with 3 cases of birth defect (1.31%). The birth defect rate of ART with cryopreserved donor sperm was significantly lower than that published by the Chinese Ministry of Health (0.86% vs 1.53%,P<0.01).</p><p><b>CONCLUSIONS</b>The safety of the offspring conceived by ART with cryopreserved donor sperm is controllable.</p>
