ABSTRACT
<p><b>OBJECTIVE</b>To investigate the value of serum beta-human chorionic gonadotropin (β-HCG) on days 9 (d9) and 11 (d11) after fresh embryo transfer (ET) and frozen-thawed embryo transfer (FET) in predicting the pregnancy outcomes.</p><p><b>METHODS</b>A total of 227 fresh ET and FET cycles performed at the Center of Reproductive Medicine, Qingyuan People's Hospital between Dec, 2012 and Feb, 2014 were analyzed. The data of serum β-HCG levels on d9 and d11 after fresh ET and FET cycles and the pregnancy outcomes were reviewed, and the ROC curve was constructed to determine the optimal cut-off level of serum β-HCG level for predicting pregnancy outcomes.</p><p><b>RESULTS</b>According to pregnancy outcomes, the cycles were divided into non-pregnancy group (group A), biochemical pregnancy group (group B), and clinical pregnancy group (group C). Significant differences were found between the mean serum β-HCG levels measured on d9 and d11 in all the 3 groups (P<0.01). The cycles in group C were further divided into 5 subgroups with single pregnancy (C1), twin pregnancy (C2), early abortion (C3), ectopic pregnancy (C4), or intrauterine pregnancy complicated with ectopic pregnancy group (C5), and all the 5 subgroups showed significant differences in β-HCG measurements between d9 and d11 (P<0.01). On d9 after ET and FET, the optimal cut-off level of serum β-HCG was 49.05 IU/L for predicting for clinical pregnancy, and was 105.15 IU/L for predicting twin pregnancy; the two corresponding cut-off levels of serum β-HCG on d11 was 51.2 IU/L and 241.75 IU/L, respectively.</p><p><b>CONCLUSION</b>The absolute serum β-HCG level on d9 and d11 after fresh ET and FET allows an accurate diagnosis of pregnancy and helps in the prediction of the pregnancy outcomes.</p>

Objective To estimate the clinical value of 4 methods of endometrium preparation for frozen‐thawed embryo transfer(FET ) cycle .Methods Total 320 FET cycles completed in center of reproductive medicine of Qingyuan people′s hospital from March 2013 to March 2015 were retrospectively analyzed ,and divided into 4 groups :natural cycle group(group A ,n=70) ,o‐vulation‐inducing cycle group(group B ,n=152) ,hormone replacement treatment(HRT) cycle group (group C ,n=74) ,down‐regu‐lated HRT cycle (group D ,n=24) .The pregnancy outcomes were followed and compared among these different 4 groups .Results In FET cycles ,the clinical pregnancy rates and implantation rates of group B ,group C and group D were significantly higher than that of group A (P0 .05) .However ,the rank of the FET cycle of group D was significantly higher than those of the other three groups(P<0 .05) .Conclusion In FET cycles ,the methods of ovulation‐inducing ,HRT and down‐reg‐ulated HRT all have favorable clinical outcomes ,and the method of down‐regulated HRT is more suitable for patients with previous implantation failure .
ABSTRACT
Objective To study the relationship between the semen quality and age in infertile men in Qingyuan.Methods 727 cases of infertile men from Reproductive Medicine Center outpatient were enrolled and divided into 5 groups:≤ 25,> 25 - 30,>30-35,>35-40,>40 age groups.The semen characteristics were carried out by calculator assistance sperm analysis(CASA) technique and Diff-Quick staining method.Results The sperm density of >30 -35 age group was the highest,but there was no significantly difference from other groups(P >0.05).Semen analysis showed that the rates of PR,PR+NP and survival sperm were on downward trends with the increase of age,but not statistically significant(P >0.05).38.19% of >25 -30 age group reached WHO′s semen parameters standard,which was the highest proportion among 5 groups.And the proportion in >40 age group was the lowest,which counted for 27.42%.Conclusion The semen quality shows a down trend with the increase of age,however,the infertility could occur in the reproductive men at any stage.
