Pregnancy outcome after ICSI with thawed testicular sperm from men with non-obstructive azoospermia compared to ICSI with ejaculated sperm from men with severe oligoasthenoteratozoospermia and IVF with normal ejaculated sperm.

The aim of the study was to evaluate the clinical pregnancy outcomes, fetal complications and malformation rate of intracytoplasmic injection of thawed cryopreseverd sperm extracted by testicular aspiration from men with non-obstructive azoospermia (NOA) compared with intracytoplasmic injection of fresh ejaculated sperm from men with severe oligoteratoasthenozoospermia (OTA) and standard in vitro fertilization using ejaculated sperm from normospermic men. The mean oocyte fertilization rate was significantly lowest for ICSI with testicular aspirated sperm (NOA group). However, there was no significant difference among the three groups in pregnancy outcomes, namely rates of spontaneous abortion, biochemical pregnancy, extrauterine pregnancy, singleton multifetal pregnancy, preterm delivery before 36 weeks' gestation, maternal complications, transfer to the neonatal intensive care unit, intrauterine growth restriction or fetal malformations. These results suggest that despite some earlier findings that intracytoplasmic injection of aspirated sperm from men with NOA is associated with lower fertilization rates and embryo quality, the pregnancy and immediate neonatal outcomes may be unaffected.

FIGO statement: Fertility preservation.

Fertility preservation is a growing field in reproductive medicine that may raise ethical questions. Preservation of fertility must be discussed with the patient if gonadotoxic treatment is required, whether in the case of benign or malignant pathology, or in the management of transgender identity. As a result, surgery or chemotherapy that has fewer adverse impacts on fertility should be proposed if this does not alter the prognosis of the disease. If the risk of infertility persists, then fertility cryopreservation should be proposed for children and adults of reproductive age. Sperm, oocytes, and gonadal tissue can be cryopreserved for many years. FIGO wishes to emphasize the importance of fertility preservation in the medical and surgical management of patients, and the importance of a specialized, multidisciplinary approach.

Severe ovarian dysgenesis and enlarged dysplastic kidneys in two siblings with normal karyotypes.

OBJECTIVE: To report a rare case of two normally karyotyped 46,XX siblings with severe ovarian dysgenesis and enlarged dysplastic kidneys. DESIGN: Case report. Rabin Medical Center, a major tertiary university-affiliated care and referral facility. PATIENT(S): A healthy 30-31-year-old woman underwent termination of two pregnancies at 22 and 23 gestational weeks because of ultrasonographic observations of enlarged kidneys in both fetuses. INTERVENTION(S): Prostaglandin-induced pregnancy terminations with feticide. MAIN OUTCOME MEASURE(S): Light microscopy observations. RESULT(S): Both siblings had a 46,XX karyotype, and the maternal alpha-fetoprotein level was within normal limits. In the first, no ovaries were identified, and in the second, bilateral streak ovaries devoid of ova were noted. In both cases, pathological examinations identified large dysplastic kidneys, with dysplastic changes in certain medullary areas. Apart from the kidneys and ovaries, all other organs were normal. CONCLUSION(S): To the best of our knowledge, this is the first report of two normally karyotyped 46,XX siblings with severe ovarian dysgenesis and renal abnormalities but without any other malformations.

Survival of frozen-thawed human ovarian fetal follicles in long-term organ culture.

Ovarian follicles obtained from second and third-trimester human fetuses survived 4 weeks in organ culture and secreted 17-beta estradiol (E(2)).

Parameters affecting successful transplantation of frozen-thawed human fetal ovaries into immunodeficient mice.

OBJECTIVE: To compare the development and survival of human fetal follicles frozen-thawed with dimethylsulfoxide (DMSO) and propandiol (PROH) in immunodeficient mice, to study the effects of host treatment with FSH, and to compare kidney and subcutaneous transplantation. DESIGN: Controlled histologic study. SETTING: Major tertiary care and referral academic center.Twenty-one women undergoing second-trimester pregnancy termination. Microscopic morphometric analysis and immunocytochemistry for proliferating-cell nuclear antigen in human fetal ovaries grafted into immunodeficient mice. RESULTS: Renal grafts that were frozen-thawed with DMSO rather than PROH survived better in the hosts (79.6% compared with 58.8%), but significantly more follicles were identified in grafts frozen-thawed with PROH (P<.001). Follicular development was observed only in FSH-treated hosts, and follicular survival and development was better in the kidney than the subcutaneous site. CONCLUSION(S): This is the first report showing development of human fetal follicles in immunodeficient mice. Freezing-thawing with PROH seems to support development and survival better than with DMSO. The kidney is a better transplantation site than the subcutaneous site, probably because of its superior vascularization. Administration of FSH to the host is essential for follicular development. Follicular development and growth was better in ovarian grafts from older fetuses, as they contained more formed follicles.

Induction of labor in pregnancies with suspected large-for-gestational-age fetuses and unfavorable cervix.

OBJECTIVES: To evaluate our single-center, single-team experience with induction of labor in pregnancies with suspected large for gestational age (LGA) fetuses. STUDY DESIGN: A retrospective case-controlled design was used. Non-diabetic patients with a suspected LGA fetus (estimated fetal weight > or =90th percentile) (group 1, n = 135) were compared with healthy patients admitted for elective induction of labor for either post-date pregnancy or a subjective perception of decreased fetal movements in the presence of normal fetal heart monitoring and biophysical profile (group 2, n = 326), and with healthy women with normal pregnancies and spontaneous onset of labor (group 3, n = 574). RESULTS: There were no between-group differences in maternal age, parity, number of prostaglandin E2 (PGE2) tablets used, instrumental delivery rate or Apgar scores. The rate of cesarean section (CS) was significantly higher in the study group (33.3%) than in group 2 (17.8%, P = 0.001) and group 3 (10.6%, P = 0.004), although this difference disappeared when the multiparous women were analyzed separately (study group: n = 58, 10.3% versus group 2: n = 169, 7.7% and group 3: n = 308, 7.8%, P = 0.6). A logistic regression model (R2 = 0.385, P < 0.001) was used to control for maternal and gestational age, nulliparity rate, number of PGE2 tablets used, birth weight, and diagnosis (group 1 versus group 2) as predictors of mode of delivery. On stepwise (forward-likelihood) analysis, only nulliparity (odds ratio (OR) 10.0, 95% confidence interval (CI) 2.8-35.6, P < 0.001) and maternal age (OR 1.2, 95% CI 1.06-1.36, P = 0.002) were independently and significantly associated with increased risk of CS. CONCLUSIONS: Induction of labor for suspected LGA fetuses, if performed at all, should be reserved for multiparous women.

[Complications of surgery for stress incontinence in women].

For some women with stress incontinence, surgery is the only effective treatment. More than 100 different operations are reported to cure stress incontinence. The reason for this variety is the fact that none of the operations is entirely satisfactory. This review aims to highlight the complications of surgery for stress incontinence in women.

Does the presence of nuclear vacuoles in human sperm selected for ICSI affect pregnancy outcome?

BACKGROUND: To verify whether or not microinjection of sperm with a normal nuclear shape but large vacuoles affects IVF-ICSI pregnancy outcome. METHODS: A comparative study testing IVF outcome parameters of IVF-ICSI, based on morphological selection of spermatozoa with normal nuclei against those based on microinjection of sperm with a normal nuclear shape but large vacuoles. An experimental group, including 28 IVF-ICSI cycles, where only embryos obtained from microinjection of spermatozoa with a normal nuclear shape but large vacuoles were transferred, was matched with a control group, including 28 IVF-ICSI cycles, where only embryos obtained from microinjection of spermatozoa with a strictly defined morphologically normal nuclear shape and content were transferred. The main outcome was IVF-ICSI pregnancy rate. RESULTS: The experimental group exhibited a significantly lower pregnancy rate per cycle and significantly higher abortion rate per pregnancy compared to the control group (18 versus 50%, and 80 versus 7%, respectively, P=0.01). CONCLUSION: Microinjection of vacuolated sperm appears to reduce the pregnancy rate and appears to be associated with early abortion.

Expression of basic fibroblast growth factor and its receptors in human ovarian follicles from adults and fetuses.

OBJECTIVE: To investigate the immunocytochemical expression and presence of mRNA transcripts for basic fibroblast growth factor (bFGF) and its four receptors (FGFR-1, -2, -3, and -4) in ovaries from human adults and fetuses. DESIGN: Immunocytochemical and reverse transcription polymerase chain reaction (RT-PCR) study. SETTING: Major tertiary care and referral academic centers. PATIENT(S): Nine women and girls undergoing laparoscopic ovarian biopsy and 26 women undergoing second- and third-trimester pregnancy terminations. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Microscopic morphometric analysis, immunocytochemistry for bFGF and its receptors, and RT-PCR analyses. RESULT(S): The proteins for bFGF, FGFR-2, FGFR-3, and FGFR-4 were identified in oocytes of all follicular classes. Immunocytochemical expression of bFGF and its receptors was detected in granulosa cells of follicles from adolescents/women but not from fetuses. There was no immunocytochemical expression of FGFR-1. Transcripts of bFGF and its four receptors were identified by RT-PCR in all samples. CONCLUSION(S): The expression of bFGF and its receptors in human ovaries suggests that bFGF might have a role in early folliculogenesis.

Possible direct cytoxicity effects of cyclophosphamide on cultured human follicles: an electron microscopy study.

PURPOSE: To evaluate the direct effect of cyclophosphamide on cultured human ovarian follicles. METHODS: Human ovarian cortical slices from premenopausal women were incubated with medium containing cyclophosphamide (0.0005-0.5 mg/mL) for 2-48 h and assessed by transmission electron microscopy. Noncultured specimens and samples cultured without cyclophosphamide were used as controls. RESULTS: There were significantly more damaged granulosa cell nuclei after incubation with 0.5 mg/mL cyclophosphamide for at least 4 h. There were also more changes in the basement membrane after incubation with cyclophosphamide at concentrations of 0.05 and 0.5 mg/mL. CONCLUSIONS: Although the cyclophosphamide dose that caused damage to the granulosa cell nuclei was above the pharmacological level, our results suggest that cyclophosphamide, and not only its active metabolite phospharamide mustard, might have a destructive effect on human follicles, as it remains in the circulation longer. This effect could be mediated by damage to the granulosa cells and perhaps the basement membrane.

Interleukin-2 production in whole blood cell cultures of women undergoing controlled ovarian hyperstimulation for assisted reproduction technology cycles.

PROBLEM: To determine whether human chorionic gonadotropin (hCG) modulates the in vitro release of interleukin (IL-2) from human peripheral lymphocytes and monocytes derived from patients undergoing controlled ovarian hyperstimulation (COH). METHOD OF STUDY: A large university-based IVF unit was used for the study. Blood was drawn thrice from 12 women undergoing our routine IVF long gonadotropin-releasing-hormone-analog protocol during the COH cycle: (1) day on which adequate suppression was obtained (Day-S); (2) day of or prior to hCG administration (Day-hCG); and (3) day of ovum pick-up (Day-OPU). At each point of time, blood was tested for sex-steroid levels and then cultured for 72 hr either without (control-culture) or with hCG (hCG-culture) or with mitogenic stimulation by phytohemagglutinin (PHA-culture). The culture-medium supernatants were tested for IL-2 levels with a commercial sandwich enzyme-linked immunoassay. RESULTS: Whole blood culture IL-2 levels increased significantly during COH until peak E2, and then decreased significantly after hCG administration. IL-2 levels were decreased in the control- and PHA-culture media on Day-OPU compared with Day-hCG. There were no significant correlations between IL-2 levels in the culture media and serum estradiol, progesterone or human chorionic gonadotropin levels. CONCLUSION: Apparently, hCG attenuates IL-2 production by mononuclear cells with and without mitogenic stimulation, irrespective of the estradiol level. This suggests that hCG may indirectly modulate the inflammatory response, resulting in the ovarian hyperstimulation syndrome.
