1/126. Rare delivery complication caused by an undiagnosed uterine septum.The role of a uterine septum, and thus, metroplasty in an infertile woman is a debatable issue. A rare complication of fetal malpresentation and impaction in the uterine cavity due to undiagnosed uterine septum in a 24-year-old primigravida who conceived after 3 years of primary infertility is reported. This case highlights that uterine anomalies should be looked for in patients with infertility and reproductive failures, and should be corrected before conception by metroplasty in order to improve reproductive outcome.- - - - - - - - - - ranking = 1keywords = conception (Clic here for more details about this article) |
2/126. Hysteroscopic cervical canal shaving: a new therapy for cervical stenosis before embryo transfer in patients undergoing in vitro fertilization.OBJECTIVE: To report a case of cervical stenosis repaired by hysteroscopic cervical shaving that created a smooth passage for ET in a patient undergoing IVF. DESIGN: Case report. SETTING: University-based IVF program. PATIENT(S): A woman with a history of multiple failed IVF attempts in whom ET was extremely difficult. INTERVENTION(S): Operative hysteroscopy with creation of a cervical tract. MAIN OUTCOME MEASURE(S): Ease of postoperative ET and outcome of IVF treatment after the hysteroscopic procedure. RESULT(S): Easy performance of ET and a resulting triplet pregnancy. CONCLUSION(S): This novel hysteroscopic repair of cervical stenosis resulted in a markedly easier ET and a viable pregnancy.- - - - - - - - - - ranking = 367.53039897666keywords = fertilization (Clic here for more details about this article) |
3/126. A new case of NSAID-induced infertility.A 38-year-old woman on piroxicam for hip osteoarthritis secondary to hip dysplasia developed secondary sterility. Ova collected for in vitro fertilization were immature and failed to fertilize. A further attempt done after piroxicam discontinuation produced seven mature ova that fertilized, allowing embryo implantation. Nonsteroidal antiinflammatory drugs may induce infertility by reducing the production of prostaglandins, most notably via inhibition of the enzyme cyclooxygenase 2. The impact of nonsteroidal antiinflammatory drug therapy on reproductive function needs to be evaluated.- - - - - - - - - - ranking = 91.882599744164keywords = fertilization (Clic here for more details about this article) |
4/126. Successful pregnancy in an infertile patient with conservatively treated endometrial adenocarcinoma after transfer of embryos obtained by intracytoplasmic sperm injection.A rare case of successful pregnancy in a woman with early-stage endometrial adenocarcinoma conservatively treated is presented. The patient, having polycystic ovaries, was initially diagnosed with hyperplasia of the endometrium and treated with several cycles of ovulation induction following intrauterine insemination. Then dilatation and curettage were carried out when hysteroscopy was performed. The histology report identified a well-differentiated adenocarcinoma of the endometrium. After repeated endometrial curettage, in-vitro fertilization and embryo transfer were introduced for immediate treatment of the patient's infertility in order to avoid the risk of recurrence of neoplastic endometrial lesions by oestrogens. A single pregnancy was achieved after transfer of the embryos obtained after intracytoplasmic sperm injection. This was performed due to the poor semen characteristics (asthenozoospermia). The patient delivered a healthy normal male infant at term. A transvaginal ultrasound examination 2 months after delivery showed a smooth, linear endometrium. Moreover, the histology report after endometrial biopsy was free of any malignancies. The patient now desires another pregnancy. We conclude that conservative treatment of early-stage endometrial adenocarcinoma in young women wishing to preserve fertility should be considered in carefully selected cases. Assisted reproductive technologies may be helpful for immediate achievement of pregnancy in such patients.- - - - - - - - - - ranking = 91.882599744164keywords = fertilization (Clic here for more details about this article) |
5/126. Twin delivery after myomectomy, in vitro fertilization, and embryo reduction in an infertile woman.A 28-year-old patient had metroplasty performed because of necrosis of a uterine fibroid. During follow-up, the left adnexa were removed because of a recurrent left ovarian cyst. The triplet gestation achieved by in vitro fertilization was reduced to twins. The living premature newborns were delivered abdominally.- - - - - - - - - - ranking = 459.41299872082keywords = fertilization (Clic here for more details about this article) |
6/126. salpingectomy for unilateral hydrosalpinx may improve in vivo fecundity.The objective of this study was to determine whether unilateral salpingectomy for hydrosalpinx could improve fecundity in women with an apparently normal contralateral tube. Two women with unilateral hydrosalpinx and with an apparently normal contralateral tube, and a long history of infertility, including failure to conceive despite several cycles of in vitro fertilization (IVF), had unilateral salpingectomies prior to considering subsequent IVF cycles. Case 1 conceived after 1 month following surgery and case 2 after 8 months without the use of assisted reproductive technology. Though the ensuing pregnancies may have been fortuitous, the possibility exists that in cases of unilateral hydrosalpinx, the performance of salpingectomy may improve fecundity without the need for IVF. Hopefully the outcome of these 2 case reports may generate interest in a larger cooperative prospective study. copyright copyright 1999 S.

7/126. Recovery of spermatogenesis and successful conception after bone marrow transplant for acute leukaemia: case report.A case is presented of a young adult male diagnosed with acute myeloid leukaemia who was treated with busulphan and cyclophosphamide, but not total body irradiation, with subsequent bone marrow transplantation. After surviving for 5 years, he and his wife experienced a period of infertility. Interestingly, the problem was found to be with the female partner and the man's sperm evaluation seemed normal. A successful pregnancy ensued following the surgical removal of a large endometrioma and treating a luteal phase deficiency. Though this may be the fifth case of proven parentage in cases of bone marrow conditioning and bone marrow transplantation in a male for control of leukaemia, we believe it is the first documented case showing a normal semen analysis despite treatment. Further studies are needed to see if chemical conditioning with busulphan and cyclophosphamide preserve the chances of sperm production better than total body irradiation.- - - - - - - - - - ranking = 4keywords = conception (Clic here for more details about this article) |
8/126. The use of gonadotrophin-releasing hormone antagonists in polycystic ovarian disease.Polycystic ovarian disease (PCOD) is characterized by anovulation, eventually high luteinizing hormone (LH) levels, with increased LH pulse frequency, and hyperandrogenism. As the aetiology of the disease is still unknown, gonadotrophin-releasing hormone (GnRH) antagonists, competitive inhibitors of GnRH for its receptor, are interesting tools in order to study and treat the role of increased LH levels and pulse frequency in this disease. Their administration provokes a rapid decrease in bioactive and immunoactive LH followed by a slower decrease in follicle-stimulating hormone (FSH). In patients with PCOD, the suppression of gonadotrophin secretion eradicates the symptoms of the disease as long as the treatment lasts. Several authors have suggested that increased plasma LH levels have deleterious effects on the fertility of women with PCOD. Indeed, fewer spontaneous pregnancies with more miscarriages are observed when plasma LH levels are high. Assisted reproduction techniques such as in vitro fertilization (IVF) have provided other clues to the role of the LH secretory pattern in women with PCOD. The number of oocytes retrieved, the fertilization rate and the cleavage rate are lower in PCOD patients undergoing IVF and this is inversely correlated with FSH:LH ratio. These abnormalities are corrected when endogenous secretion of LH is suppressed. On the other hand, implantation and pregnancy rates after IVF are similar to those observed in control women. New GnRH antagonists are devoid of side effects and suppress LH secretion within a few hours without a flare-up effect. This action lasts for 10-100 hours. When GnRH antagonists are associated with i.v. pulsatile GnRH, this combination both suppresses the effect of endogenous GnRH and because of the competition for GnRH receptors restores a normal frequency of LH secretion. We have studied two women with PCOD, administering first 10 mg s.c. every 72 hours for 7 days of the GnRH antagonist Nal-Glu, then adding on top i.v. pulsatile GnRH: 10 micrograms/pulse every 90 minutes for 15 days. We thus succeeded in normalizing LH secretion pattern and observed a significant decline in testosterone levels. We failed to induce appropriate ovarian response and ovulation. In conclusion, the combination of GnRH antagonist and GnRH pulsatile treatment can re-establish normal LH secretory pattern in patients with PCOD. The failure to induce ovulation with this regimen suggests the existence of an inherent ovarian defect in women with PCOD.- - - - - - - - - - ranking = 183.76519948833keywords = fertilization (Clic here for more details about this article) |
9/126. Midcycle administration of single-dose GnRHa for luteal phase failure in women with ovarian hyperstimulation. A report of five cases.BACKGROUND: Exogenous administration of gonadotropin-releasing hormone agonist (GnRHa) induces an endogenous midcycle gonadotropin surge. However, its use to induce ovulation and maintain luteal function in non-in vitro fertilization patients who receive ovarian stimulation is unknown. CASES: Five infertile women who underwent controlled ovarian hyperstimulation with human menotropin developed multiple ovarian follicles. In an attempt to circumvent the potential ovarian hyperstimulation syndrome, 1 mg of leuprolide acetate was administered subcutaneously to three patients in an attempt to induce the endogenous luteinizing hormone surge. All three patients began menstruation six to seven days after GnRHa administration with serum progesterone levels between 0.2 and 0.5 ng/mL. Similar ovarian stimulation cycles with ovulation induced by human chorionic gonadotropin in these individuals revealed a normal luteal phase length and midluteal progesterone levels. When double doses of leuprolide acetate were used on two patients, normal luteal length and midluteal serum progesterone levels occurred. CONCLUSION: A single bolus of GnRHa during the late follicular phase may be inadequate to initiate normal luteal function in cycles with ovarian hyperstimulation.- - - - - - - - - - ranking = 91.882599744164keywords = fertilization (Clic here for more details about this article) |
10/126. Sigmoid endometriosis and ovarian stimulation.In-vitro fertilization (IVF) and ovarian stimulation are frequently performed in patients with endometriosis. Although endometriosis is a hormone-dependent disease, the rate of IVF complications related to endometriosis is low. We report four cases of severe digestive complications due to the rapid growth of sigmoid endometriosis under ovarian stimulation. In three patients, sigmoid endometriosis was diagnosed at laparoscopy for sterility. Because of the absence of digestive symptoms or repercussion on the bowel, no bowel resection was performed before ovarian stimulation. All patients experienced severe digestive symptoms during ovarian stimulation, and a segmental sigmoid resection had to be performed. Analysis of endoscopic and radiological data demonstrated that bowel lesions of small size may rapidly enlarge and become highly symptomatic under ovarian stimulation. At immunohistochemistry, these infiltrating lesions displayed high populations of steroid receptors and a high proliferative index (Ki-67 activity), suggesting a strong dependence on circulating ovarian hormones and a potential for rapid growth under supraphysiological oestrogen concentrations. Clinicians should be aware of this rare but severe digestive complication of ovarian stimulation. The early diagnosis of such lesions may help the patients to avoid months of morbidity falsely attributed to ovarian stimulation side effects. Further experience is necessary to determine the optimal attitude when diagnosing a small and asymptomatic endometriotic bowel lesion before ovarian stimulation.- - - - - - - - - - ranking = 91.882599744164keywords = fertilization (Clic here for more details about this article) |
