Résumé

Fertility preservation technology provides an effective method of protecting fertility resources for young patients with malignant tumors, allowing them to offspring after their fertility is impaired. However, the development of this technology has caused many social and ethical controversies. From the perspective of ethics, this paper discussed the ethical issues faced by young female patients in the implementation of fertility preservation, including whether it is necessary to preserve fertility, the ownership of the preserved fertility resources and the fair and equitable distribution of health resources involved in its implementation process, and identifies these issues and controversies from ethical view. In order to eliminate public doubts and misunderstandings about the technology of fertility preservation, ethical principles of benefit and non-harm, informed consent, prudent application, and ethical supervision have to be followed in the process of providing fertility preservation services, so as to promote the further development and application of fertility preservation technology.

Résumé

Objective To investigate the application value of two kinds of endometrial preparation in patients with thin endometrium of frozen thawed embryo transfer cycle.Methods A retrospective analysis of the clinical data of 82 cycle of 76 patients was carried out.According to the difference of the endometrial preparation,the two groups were divided into two groups.One group was progynova group (42 cycles),and the other group was femonston group (40 cycles).Baseline information,endometrial status and pregnancy outcome were compared between the two groups.Results There was no significant difference in baseline data (age,years of infertility,body mass index,basal hormone level) between the two groups.There was no significant difference in endometrial thickness[progynova group (5.52 ± 0.74) mm,femonston group (5.33 ± 0.66) mm,t =1.290,P =0.203],endometrial volume (progynova grouP < 2mL and ≥ 2mL 38 patients and 4 patients,that of femonston group 36 cases and 4 cases,x2 =0.005,P =0.942),endometrial type (progynova group A,B,C type 35 cases,7 cases,0 case,those of emonston group 34 cases,6 cases,0 case,x2 =0.043,P =0.836) and blood flow (progynova group Ⅰ + Ⅱ and Ⅲ 34 cases and 8 cases,those of femonston group 35 cases and 5 cases,x2 =0.658,.P =0.417) between the two groups before treatment.After administration,endometrial thickness [progynova group (6.90 ± 0.62) mm,femonston group (7.60 ± 0.63) mm,t =5.04,P =0.000],neointimal growth [progynova group (1.67 ± 0.48) mm,femonston group (3.20 ± 0.61) mm,t =12.74,P =0.000],ratio of endometrial volume more than or equal to 2 mL [progynova group 52.38 % (22/42),femonston group 80.00% (32/40),x2 =6.95,P =0.008],and ratio of endometrial blood flow type Ⅲ [progynova group 38.10% (16/42),femonston group 70.00% (28/40),x2 =8.387,P =0.004] of femonston group were higher than those of progynova group.The dosage[progynova group (112.43 ± 16.39)mg,femonston group (78.85 ± 10.17)mg,t =11.08,P =0.000] was lower than that of progynova group,and the difference was statistically significant.There was no significant difference in the two groups in endometrial type (progynova group A,B,C 30 cases,12 cases and 0 case,those of femonston group 28,12 and 0,x2 =0.020,P =0.887) after the treatment.There was no significant difference in the number of transplanted embryos (progynova group 1.78 ± 0.47,femonston group 1.77 ± 0.42,t =0.108,P =0.914),high quality embryo rate [progynova group 74.67 % (56/75),femonston group 73.24 % (52/71),x2 =0.039,P =0.844],implantation rate [progynova group 14.67 % (11/75),femonston group 16.90% (12/71),x2 =0.137,P =0.711],biochemical pregnancy rate[progynova group 38.10% (16/42),femonston group 40.00% (16/40),x2 =0.031,P =0.860] and clinical pregnancy rate [progynova group 28.57 % (12/42),femonston group 32.50% (13/40),x2 =0.149,P =0.699] between the two groups.Conclusion Femonston with less dosage,better improvement of the endometrial thickness,endometrial volume,endometrial blood flow of patients with thin endometrium of patients can obtain similar pregnancy outcomes compared with progynova.

Résumé

Objective To study sperm mRNA transcript expression of CRISP2 gene in the semen of patients with different types of spermatogenetic failure. Methods A total of 150 male infertility patients were divided into normal group, asthenozoospermia group and oligozoospermia group(n=50 for each group). Total RNA was extracted from sperm cells. Re-al-time quantitative reverse transcription polymerase chain reaction (qRT-PCR) method was used to detect CRISP 2 gene mRNA levels in three groups. Results There was a significantly higher expression of CRISP2 in normal group (10.281 ± 2.173) than that of asthenozoospermia group (2.092±0.969, P<0.05). There was no significant difference in the expression of CRISP2 between normal group and oligozoospermia group (9.420±2.794, P>0.05). The relative expression of CRISP2 was sig-nificantly lower in asthenozoospermia group than that of oligozoospermia group (P<0.05). Conclusion The CRISP2 expres-sion was significantly different in patients with different types of spermatogenic failure. The reduced expression of CRISP 2 may lead to the decreased sperm motility.
