1/67. Spontaneous pregnancy following therapeutic approach of an infertile man with aspermia/obstructive azoospermia.The combination of aspermia and obstructive azoospermia in the same infertile man is a rather rare entity. In the case reported here, all diagnostic criteria as well as subsequent recovery following two operations are compatible with an inflammatory origin. In such cases assisted reproduction should be recommended. However, in this case, an early spontaneous pregnancy rendered this unnecessary.- - - - - - - - - - ranking = 1keywords = pregnancy (Clic here for more details about this article) |
2/67. Birth of twin males with normal karyotype after intracytoplasmic sperm injection with use of testicular spermatozoa from a nonmosaic patient with Klinefelter's syndrome.OBJECTIVE: To report the birth of healthy twin males after the use of testicular spermatozoa from a nonmosaic patient with Klinefelter's syndrome. DESIGN: Case report. SETTING: Private reproduction center with university affiliation. PATIENT(S): A couple undergoing intracytoplasmic sperm injection (ICSI) combined with testicular sperm extraction because of the husband's secretory azoospermia and a nonmosaic 47,XXY peripheral blood karyotype. The wife, a healthy female, presented with a history of oligomenorrhea. INTERVENTION(S): ICSI was performed using testicular spermatozoa; 3 mM pentoxifylline solution was used to induce sperm motility because the spermatozoa recovered were all immotile. MAIN OUTCOME MEASURE(S): Normal fertilization, embryo cleavage, pregnancy outcome, and peripheral blood karyotype of the newborns. RESULT(S): Thirteen metaphase II oocytes were injected. Seven of them fertilized normally and six did not fertilize. Three good-quality embryos (4-cell stage class II) were transferred, and four were cryopreserved at the two-cell and four-cell stages using a slow freezing protocol. Twelve days after ET, a beta-hCG determination was positive. Ultrasonographic examination revealed three intrauterine fetal sacs, but one of them showed a fetal pole without cardiac activity and vanished in subsequent ultrasonographic examinations. The patient delivered twins with normal male peripheral blood karyotypes. CONCLUSION(S): Normal outcome after the use of testicular sperm extraction and ICSI in a nonmosaic patient with Klinefelter's syndrome reaffirms the notion of low transmission risk of this gonosomal aneuploidy.- - - - - - - - - - ranking = 0.2keywords = pregnancy (Clic here for more details about this article) |
3/67. Recovery of ejaculated spermatozoa for intracytoplasmic sperm injection after anti-inflammatory treatment of an azoospermic patient with genital tract infection: a case report.In this paper our experiences with anti-inflammatory treatment of an infertile patient with azoospermia and concomitant silent genital infection are reported. The patient was referred to our fertility centre with prediagnosed non-obstructive azoospermia and no spermatozoa were found in the ejaculate on two occasions. The patient showed leukocytospermia and was suspected to be affected by genital infection. Therefore, anti-inflammatory treatment was initiated and 8 weeks later examination of the ejaculate revealed a decreased number of leukocytes and the presence of few but motile spermatozoa. Subsequently, two ICSI cycles were performed with anti-inflammatory therapy in parallel and a sufficient number of spermatozoa could be retrieved for injection. However, in a third cycle without previous treatment, examination of the ejaculate again revealed azoospermia and leukocytospermia. It is concluded that, in cases of azoospermia and chronic genital infection, some patients will benefit from anti-inflammatory treatment prior to and during ICSI treatment. This may allow retrieval of spermatozoa from the ejaculate and thus may avoid the need for a therapeutic testicular biopsy. Using this approach, sufficient spermatozoa in three out of four ICSI cycles could be retrieved and a pregnancy was finally achieved.- - - - - - - - - - ranking = 0.2keywords = pregnancy (Clic here for more details about this article) |
4/67. 45,X/46,X,r(Y) karyotype transmitted by father to son after intracytoplasmic sperm injection for oligospermia. A case report.BACKGROUND: The advent of assisted reproductive techniques, such as intracytoplasmic sperm injection (ICSI), has permitted conception and successful pregnancy for an increasing population of infertile men. Approximately 13.7% of infertile men with aspermia and 4.6% with oligospermia have a coexistent chromosome abnormality. Although the ICSI procedure appears safe thus far, early studies are in progress to evaluate outcomes of such pregnancies. For men whose infertility is linked to genetic conditions, it is an unprecedented challenge to predict the potential effects on their offspring. CASE: At 18 weeks' gestation, a 45,X/46,X,r(Y) karyotype was found on genetic amniocentesis performed for advanced maternal age. The pregnancy was achieved by ICSI using sperm from the husband, who was infertile due to severe oligospermia. Subsequently the same karyotype was found in the father. To our knowledge, this is the first reported case of familial transmission of ring y chromosome. CONCLUSION: It is strongly recommended that ICSI and other new assisted reproductive techniques be preceded by genetic screening for male infertility as well as other indications warranted by the family history since traditional risk assessment may require revision and outcomes may be uncertain in some cases.- - - - - - - - - - ranking = 0.4256188736246keywords = pregnancy, gestation (Clic here for more details about this article) |
5/67. Birth of a healthy infant after conception with round spermatids isolated from cryopreserved testicular tissue.OBJECTIVE: To report a case of nonobstructive azoospermia in which round spermatids recovered from thawed testicular tissue were used for injection. DESIGN: Case report. SETTING: reproductive medicine Unit, S.I.S.ME.R. PATIENT(S): A 33-year-old azoospermic man. INTERVENTION(S): Intracytoplasmic sperm injection with frozen-thawed spermatids. MAIN OUTCOME MEASURE(S): fertilization, embryo cleavage, pregnancy, and delivery. RESULT(S): Birth of a healthy, chromosomally normal girl. CONCLUSION(S): Frozen-thawed testicular round spermatids from a patient with a history of incomplete spermatogenesis can maintain their viability and their capacity to fertilize and to lead to full-term pregnancy.- - - - - - - - - - ranking = 0.4keywords = pregnancy (Clic here for more details about this article) |
6/67. Successful pregnancy by intracytoplasmic sperm injection after radiotherapy-induced azoospermia.A 27-year-old male, who underwent excision and radiotherapy for a pineal gland germinoma four years previously, subsequently developed panhypopituitarism and, thus, complete azoospermia. Gonadotrophin replacement therapy resulted in the production of a small number of motile spermatozoa which were used for Intracytoplasmic Sperm Injection (ICSI) into oocytes obtained from his wife. After successful fertilization and embryo transfer, a singleton intrauterine pregnancy was achieved which resulted in the normal delivery of a morphologically normal male live infant at term.- - - - - - - - - - ranking = 1keywords = pregnancy (Clic here for more details about this article) |

8/67. Successful twin pregnancy in a dual-transplant couple resulting from in-vitro fertilization and intracytoplasmic sperm injection: case report.There are numerous reports of successful pregnancy following liver transplantation. Little information is available regarding the incidence and management of infertility in transplant recipients, particularly the use of artificial reproductive technologies. We present a case of a successful twin pregnancy resulting from in-vitro fertilization with intracytoplasmic sperm injection (IVF/ICSI) in a liver transplant recipient, whose partner was a renal transplant recipient with severe oligozoospermia. With careful evaluation and monitoring, and the involvement of appropriate consultants, artificial reproductive technologies can be safely used in transplant recipient couples experiencing infertility.- - - - - - - - - - ranking = 1.2keywords = pregnancy (Clic here for more details about this article) |
9/67. prenatal diagnosis of meconium peritonitis in a twin pregnancy after intracytoplasmic sperm injection. A case report.BACKGROUND: meconium peritonitis occurring in pregnancies following artificial reproductive techniques (art) is rare. We report the first case of meconium peritonitis following intracytoplasmic sperm injection (ICSI). CASE: A 37-year-old woman attended our in vitro fertilization (IVF) program because her husband suffered from hypospermatogenetic azoospermia due to cancer surgery and radiotherapy. The patient achieved a twin pregnancy through ICSI from testicular sperm extraction at our IVF center. meconium peritonitis, fetal ascites, polyhydramnios, bowel dilatation, hydrocele and intraabdominal calcification were noted in one of the twins on ultrasound at 30 weeks' gestation. cesarean section due to breech presentation in labor was performed at 36 weeks' gestation. A normal female and male infant with a distended abdomen were delivered. Emergency laparotomy was performed on the male twin because of dyspnea. A 0.2-cm perforation was found in the terminal ileum. Ileotomy was performed and closed after 27 days. CONCLUSION: prenatal diagnosis of meconium peritonitis is possible through careful ultrasonographic examination, and early surgical intervention and intensive postoperative support are required to improve the prognosis.- - - - - - - - - - ranking = 1.0512377472492keywords = pregnancy, gestation (Clic here for more details about this article) |
10/67. Achieving pregnancy against the odds: successful implantation of frozen-thawed embryos generated by ICSI using spermatozoa banked prior to chemo/radiotherapy for Hodgkin's disease and acute leukaemia.Two cases are reported of successful pregnancies following long-term semen banking prior to chemotherapy and radiotherapy for malignancy. With the first case, the patient banked semen at the age of 20 years prior to chemotherapy for Hodgkin's disease; 11 years later the thawed semen was used for IVF with intracytoplasmic sperm injection (ICSI), resulting in twins being born following the transfer of frozen-thawed embryos. In the second case, the patient banked semen at the age of 17 years prior to chemotherapy and radiotherapy for acute myeloid leukaemia; 8 years later it was used for ICSI, resulting in triplets being born following the transfer of frozen-thawed embryos. These cases support long-term semen banking for men whose future fertility may be compromised by suppression of spermatogenesis secondary to administration of chemo/radiotherapy treatment. The advent of successful ICSI combined with embryo cryopreservation has increased the chance of thawed cryopreserved semen achieving fertilization. Banking of a single ejaculate prior to commencement of chemotherapy/radiotherapy treatment may preserve potential fertility without compromising the oncology treatment.- - - - - - - - - - ranking = 0.8keywords = pregnancy (Clic here for more details about this article) |
