1/99. 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 = 1keywords = embryo (Clic here for more details about this article) |
2/99. 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 = 0.25keywords = embryo (Clic here for more details about this article) |
3/99. 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 = 1.5keywords = embryo (Clic here for more details about this article) |
4/99. 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 = 1keywords = embryo (Clic here for more details about this article) |
5/99. Ectopic pregnancy after transmyometrial embryo transfer: case report.OBJECTIVE: To report a case of ectopic pregnancy after transvaginal transmyometrial ET. DESIGN: Case report. SETTING: University-based IVF program. PATIENT(S): A woman with tubal subfertility and a history of difficult ETs. INTERVENTION(S): Transvaginal transmyometrial ET performed to avoid a difficult transcervical ET. MAIN OUTCOME MEASURE(S): Expected improvement in the pregnancy rate in a selected group of patients. RESULT(S): Tubal pregnancy. CONCLUSION(S): Transmyometrial ET is an attractive alternative to difficult transcervical ET but is not free of complications.- - - - - - - - - - ranking = 1keywords = embryo (Clic here for more details about this article) |
6/99. Successful pregnancy after 24 consecutive fetal losses: lessons learned from surrogacy.OBJECTIVE: To offer surrogacy as a treatment option to patients in whom maternal rather than fetal factors are responsible for high-order unexplained habitual abortions. DESIGN: Case report. SETTING: University hospital. PATIENT(S): A 36-year-old woman with 24 consecutive abortions over 11 years. INTERVENTION(S): A regular IVF procedure in the aborting woman and transfer of two good-quality embryos to the surrogate mother, who had previously received hormones. MAIN OUTCOME MEASURE(S): Ovarian response, oocytes, fertilization, and embryo quality in the aborting patient. Endometrial thickness, implantation, pregnancy, and delivery in the surrogate mother. RESULT(S): Transfer of two embryos to the surrogate mother led to a clinical pregnancy, which was uneventful until term. cesarean section was performed for breech presentation, with delivery of a healthy male. CONCLUSION(S): Surrogacy can be offered as a treatment option to patients in whom maternal rather than fetal factors are responsible for high-order unexplained habitual abortions.- - - - - - - - - - ranking = 0.75keywords = embryo (Clic here for more details about this article) |
7/99. polycystic ovary syndrome, infertility, familial thrombophilia, familial hypofibrinolysis, recurrent loss of in vitro fertilized embryos, and miscarriage.OBJECTIVE: To study reversible determinants of infertility and recurrent loss of transferred embryos after failure of 7 of 10 embryo transfers, 1 live birth, and 2 miscarriages. DESIGN: Measures of thrombophilia, hypofibrinolysis, reproductive hormones, and androgenic steroids before and after metformin therapy. SETTING: Outpatient clinical research center. PATIENT(S): A 32-year-old amenorrheic, infertile woman with polycystic ovary syndrome (PCOS) who had 7 of 10 embryo transfers fail, 1 premature live birth, and 2 miscarriages at 8 and 17 weeks. INTERVENTION(S): metformin (2.55 g/d) was given to ameliorate the endocrinopathy of PCOS. MAIN OUTCOME MEASURE(S): Coagulation, insulin, reproductive hormones, and androgenic steroids. RESULT(S): The propositus had thrombophilia (familial protein s deficiency [free protein S 32%; normal >/=65%]). She also had familial hypofibrinolysis with 4G4G polymorphism of the plasminogen activator inhibitor (PAI-1) gene and high PAI-1 activity (PAI-Fx), 42.5 U/mL, normal <21.1. polycystic ovary syndrome was characterized by amenorrhea, polycystic ovaries, high fasting serum insulin (39 microU/mL, normal <20), androstenedione (763 ng/dL, normal <250), and testosterone (229 ng/dL, normal <83). After she received metformin for 4 months, PAI-Fx normalized (12.4 U/mL), as did insulin (12 microU/mL), androstenedione (185 ng/dL), and testosterone (39 ng/dL); weight fell from 109 to 91.3 kg (16%). CONCLUSION(S): metformin reversed the endocrinopathy of PCOS. Familial thrombophilia and hypofibrinolysis may lead to thrombosis-mediated uteroplacental vascular insufficiency, failure to achieve pregnancy after embryo transfer, and miscarriage.- - - - - - - - - - ranking = 2keywords = embryo (Clic here for more details about this article) |
8/99. Successful pregnancy following in vitro fertilization-embryo transfer despite imminent ovarian failure.There have been previously published several anecdotal cases of women in apparent or imminent ovarian failure who subsequently ovulated and became pregnant. Many of these women had been treated with estrogen. A series of cases were reported where women with hypergonadotropic hypogonadism who failed to stimulate despite gonadotropin therapy were able to ovulate when treated with pharmacologic doses of estrogen alone or in combination with human menopausal gonadotropins. Presented herein is a case of a woman with imminent ovarian failure with tubal disease who failed to stimulate with gonadotropins alone but was successful with estrogen and gonadotropins. We believe this is the first successful case of hypergonadotropic hypogonadism to conceive by in vitro fertilization.- - - - - - - - - - ranking = 1keywords = embryo (Clic here for more details about this article) |
9/99. methotrexate for cesarean scar pregnancy after in vitro fertilization and embryo transfer. A case report.BACKGROUND: Cesarean scar pregnancy is an exceedingly rare occurrence. We present the first case of cesarean scar pregnancy following in vitro fertilization-embryo transfer (IVF-ET). CASE: A 40-year-old woman with a history of a previous cesarean section presented with five years of unexplained infertility. The patient complained of abdominal pain 16 days after embryo transfer. ultrasonography revealed a gestational sac with cardiac activity located outside the lower segment of the uterus. dilatation and curettage was performed due to misdiagnosis of inevitable abortion. Two weeks later, repeated sonography demonstrated a sacculus, 4.07 x 4.07 cm, within the uterine isthmus with only 7.1 mm of thickness separating the sac from the urinary bladder. Normal cervical length without ballooning was noted. Cesarean scar pregnancy was diagnosed. Local injection of methotrexate (MTX) under ultrasound guidance was performed. plasma beta-hCG levels declined from 23,328 to 8 mlU/mL within two months. CONCLUSION: For women with cesarean scar pregnancy who desire fertility, conservative treatment using MTX is an excellent choice.- - - - - - - - - - ranking = 1.5keywords = embryo (Clic here for more details about this article) |
10/99. Bilateral undescended ovaries: association with infertility and treatment with IVF.OBJECTIVE: To describe the clinical findings in a patient with bilateral undescended ovaries and infertility who was successfully treated by IVF. DESIGN: Case report. SETTING: University hospital. PATIENT(S): A 35-year-old woman with bilateral undescended ovaries. INTERVENTION(S): hysterosalpingography, laparoscopy, and an IVF cycle. MAIN OUTCOME MEASURE(S): Anatomic description and pregnancy test. RESULT(S): This patient conceived and delivered a twin gestation after laparoscopic retrieval of oocytes and transfer of two blastocysts. CONCLUSION(S): Bilateral undescended ovaries is a rare condition that can be associated with infertility but can be successfully treated by IVF.- - - - - - - - - - ranking = 2.6238033317975keywords = blastocyst (Clic here for more details about this article) |
