1 Retraction PRDM9 gene polymorphism may not be associated with defective spermatogenesis in the Chinese Han population. 2013

He, Xiao-Jin / Ruan, Jian / Du, Wei-Dong / Cao, Yun-Xia / Chen, Gang / Zuo, Xian-Bo / Peng, Yu-Wan / Wu, Huan / Song, Bing / Zhang, Xue-Jun. ·Reproductive Medicine Center, Department of Obstetrics and Gynecology, The First Affiliated Hospital of Anhui Medical University. ·Syst Biol Reprod Med · Pubmed #23190393.

ABSTRACT: PRDM9 is essential for the progression through early meiotic prophase, including double strand break repair, homologous chromosome pairing, and sex body formation during spermatogenesis. In order to evaluate the association of the PRDM9 gene variants with defective spermatogenesis in the Chinese Han population, we assessed two single nucleotide polymorphisms (SNPs) in the PRDM9 gene (rs1874165 and rs2973631) using Sequenom iplex technology in 309 cases of severely defective spermatogenesis (199 cases with non-obstructive azoospermia and 110 cases with severe oligozoospermia) and 377 controls. The allele frequencies of the SNPs were not statistically different between the study groups and the controls (P =ā€‰0.95 in rs1874165 and Pā€‰=ā€‰0.80 in rs2973631, respectively). The genetic model analysis of the two SNPs indicated that these SNPs variants may not be associated with defective spermatogenesis in the Chinese Han population.

2 Retraction Failed fertilization after clinical intracytoplasmic sperm injection. 2010

ABSTRACT: Intracytoplasmic sperm injection (ICSI) has resulted in pregnancy and birth for many couples, including those with severe male factor infertility. However, even after ICSI, complete failure of fertilization occurs in 1-3% of cycles. Most cases occur due to low number of mature oocytes, failure of oocyte activation or non-availability of appropriate spermatozoa for injection. Given the significant emotional and financial involvement in assisted reproductive cycles, failure of fertilization in all mature oocytes is a distressful event. It is not predictable. Since follow-up ICSI cycles result in fertilization in 85% of cases, repeated ICSI attempts are suggested. Physicians should counsel patients experiencing repeated failure of fertilization after ICSI cycles about available options including donated oocytes/embryos, donor sperm insemination, adoption or remaining childless if these choices are not acceptable due to religious or ethical reasons. This review discusses the causes and remedies for failed fertilization after clinical ICSI.

3 Retraction Reconstructive, organ-preserving microsurgery in tubal infertility: still an alternative to in vitro fertilization. 2010

Schippert, Cordula / Bassler, Christina / Soergel, Philipp / Hille, Ursula / Hollwitz, Bettina / Garcia-Rocha, Guillermo-Jose. ·Department of Obstetrics and Gynecology, Division of Reproductive Medicine, OE 6410, Hannover Medical School, Carl-Neuberg-Str. 1, 30625 Hannover, Germany. schippert.cordula@mh-hannover.de ·Fertil Steril · Pubmed #19782355.

ABSTRACT: In this retrospective study, we observed a total of 553 patients with tubal infertility who underwent microsurgical reconstructive surgery of the fallopian tubes (including adhesiolysis, anastomosis, fimbrioplasty, salpingostomy, and refertilization after former sterilization). The pregnancy (43.4%) and birth (29.2%) rates after microsurgery for acquired tubal damages (abortion: 6.4%; ectopic pregnancy: 7.9%) were higher than after single in vitro fertilization (28.4% and <20%, respectively; data from German IVF register). The pregnancy (73%) and birth (50.6%) rates after the reversal of sterilization also were higher (abortion: 15.7%; ectopic pregnancy: 6.7%). The advantages of reconstructive microsurgery over in vitro fertilization include the ideally permanent restoration of a woman's ability to conceive naturally in every cycle that she ovulates, a high postoperative birth rate overall, and avoidance of multiple births.

4 Retraction Submucous myomas and their implications in the pregnancy rates of patients with otherwise unexplained primary infertility undergoing hysteroscopic myomectomy: a randomized matched control study. 2010

Shokeir, Tarek / El-Shafei, Muhammed / Yousef, Hamed / Allam, Abdel-Fattah / Sadek, Ehab. ·Department of Obstetrics and Gynecology, Mansoura University Hospital, Mansoura Faculty of Medicine, Mansoura, Egypt. tarekshokeir@hotmail.com ·Fertil Steril · Pubmed #19406399.

ABSTRACT: OBJECTIVE: To determine whether hysteroscopic myomectomy for submucous fibroids in women with unexplained primary infertility achieved better pregnancy rates than no intervention. DESIGN: Prospective randomized matched control trial. SETTING: Tertiary university fertility care unit. PATIENT(S): From January 1999 to February 2006, a total of 215 women with unexplained primary infertility and with ultrasonographically diagnosed submucous myomas as the sole cause for fertility failure were recruited. INTERVENTION(S): Women were randomly allocated to one of two pretreatment groups matched by age. Hysteroscopic myomectomy was performed in the study group (n = 101). Diagnostic hysteroscopy and myoma biopsy was performed in the control group (n = 103). No fertility therapy was given for either group. MAIN OUTCOME MEASURE(S): Clinical pregnancy rates according to patient and myoma characteristics. RESULT(S): The baseline characteristics of both patients and submucous myomas were comparable. Among patients with complete follow-up, a total of 93 (45.6%) pregnancies occured-64 (63.4%) in the study group and 29 (28.2%) in the control group. Women in the study group had a better possibility of becoming pregnant after hysteroscopic myomectomy with a relative risk of 2.1 (95% confidence interval, 1.5-2.9). No difference in pregnancy rates was observed according to size, number, and location of myomas in both groups. However, fertility rates appeared to increase after hysteroscopic myomectomy of type 0 and type I myomas (P < 0.05). In contrast, for the subgroup of patients with type II myomas, no difference in fertility rates were noted. CONCLUSION(S): Hysteroscopic myomectomy for submucous fibroids in women with unexplained primary infertility is effective in achieving a better pregnancy rate. We think that a multicenter study should be conducted before evaluating the impact of submucous myoma characteristics on fertility outcome.
