1/7. Triploid pregnancy after ICSI of frozen testicular spermatozoa into cryopreserved human oocytes: case report.Although freezing oocytes is ethically more acceptable than cryopreservation of embryos, variable oocyte survival, fertilization rate and possible risk of increased ploidy after cryopreservation have precluded the widespread clinical application of oocyte cryopreservation in assisted reproduction techniques. We report a triploid pregnancy from intracytoplasmic sperm injection of recombinant FSH-stimulated frozen/thawed testicular spermatozoa into cryopreserved oocytes in a hormone replacement cycle. To our knowledge, this is the first report of a pregnancy where both gametes have been frozen. It illustrates the need for further research when applying new techniques in assisted reproduction.- - - - - - - - - - ranking = 1keywords = fertilization (Clic here for more details about this article) |
2/7. Spontaneous conception in the presence of stage IIIC endometrioid ovarian cancer.OBJECTIVE: To describe a rare case of spontaneous conception in a patient with a preexisting metastatic ovarian cancer. DESIGN: Case report. SETTING: University hospital. PATIENT(S): A 39-year-old Asian woman who conceived while undergoing an evaluation for primary infertility and newly detected bilateral adnexal masses. INTERVENTION(S): Staging laparotomy and total abdominal hysterectomy and bilateral salpingo-oophorectomy. MAIN OUTCOME MEASURE(S): Anatomic pathology diagnosis. RESULT(S): Blighted ovum and stage IIIC endometrioid adenocarcinoma of ovary. CONCLUSION(S): Metastatic ovarian cancer does not prevent either spontaneous ovulation or spontaneous conception.- - - - - - - - - - ranking = 0.48184818593769keywords = conception (Clic here for more details about this article) |
3/7. subclavian vein thrombosis: a late complication of ovarian hyperstimulation syndrome.Two cases of subclavian vein thrombosis following ovarian stimulation for in-vitro fertilization and subsequent ovarian hyperstimulation syndrome (OHSS) are described. Both occurred several weeks after complete resolution of the OHSS. The site of the lesions and their timing suggest that there is a generalized disturbance of coagulation associated with OHSS, which persists beyond the duration of the clinical syndrome.- - - - - - - - - - ranking = 1keywords = fertilization (Clic here for more details about this article) |
4/7. Maternal phenylketonuria: the outcome of pregnancy.This report documents the outcome of two pregnancies is a woman with phenylketonuria (PKU) who was treated with a low phenylalanine diet before conception and during pregnancy. Her first pregnancy resulted in an abortion at 17 wk. During the second pregnancy the patient was unable to maintain the right diet consistently, and her blood phenylalanine levels in the first and second trimester were elevated. This pregnancy ended in the birth of a growth retarded microcephalic infant after an amenorrhea of 42 wk. The infant has maintained a normal growth velocity below the tenth percentile, and has not shown signs of mental retardation.- - - - - - - - - - ranking = 0.080308030989616keywords = conception (Clic here for more details about this article) |
5/7. Placental changes in a first trimester missed abortion in maternal systemic lupus erythematosus with antiphospholipid syndrome; a case report and review of the literature.The placental lesions generally attributed to the effects of systemic lupus erythematosus (SLE) on the decidual and placental villi include decidual vasculopathy, placental infarcts and possibly intrauterine growth retardation. The maternal decidual vessels in SLE show a lesion termed "acute atherosis" which is histologically similar to acute vascular rejection in a transplanted kidney. These changes can be so extensive as to result in complete vascular occlusion, decreased placental perfusion and resultant placental villous infarction. In currettings from products of conception in the first trimester, acute atherosis is a rare finding. We describe striking decidual vasculopathy and extensive villous infarction in a case of a first trimester missed abortion in a patient with SLE who had anticardiolipin antibodies (ACL), both immunoglobulin (IgG) and IgM, and lupus anticoagulant (LA) in her serum. To the best of our knowledge, this is the first report of acute atherosis and villous infarction in a first trimester placenta in association with SLE and/or ACL and LA. Pathologists should be aware of these changes and alert clinicians to the possibility of SLE or antiphospholipid and/or anticardiolipin antibodies.- - - - - - - - - - ranking = 0.080308030989616keywords = conception (Clic here for more details about this article) |
6/7. Quadruplet in vitro fertilization pregnancy complicated by fetal reduction and leiomyoma.A woman had a quadruplet IVF pregnancy with a leiomyomatous uterus. pregnancy resulted in the birth of one baby after missed abortion of one fetus and selective reduction of two others. The woman had a left deep calf vein thrombosis in the first half of pregnancy.- - - - - - - - - - ranking = 4keywords = fertilization (Clic here for more details about this article) |
7/7. Simultaneous bilateral tubal pregnancy following in-vitro fertilization and embryo transfer.A case of simultaneous bilateral tubal pregnancy resulting from in-vitro fertilization and embryo transfer is presented. Repeated transvaginal ultrasound examinations confirmed an intrauterine sac but no fetus. A diagnosis of early missed abortion was incorrectly made and a curettage was performed. The pathological examination showed the presence of decidua and Arias-Stella phenomenon but no chorionic villi. Diagnostic laparoscopy and laparotomy performed 40 days after embryo transfer (eighth week of gestation), revealed bilateral tubal pregnancy. Bilateral salpingectomy was performed.- - - - - - - - - - ranking = 5keywords = fertilization (Clic here for more details about this article) |
