RESUMO

The medical and psychological treatment for a 37-year-old Caucasian G6 P1051 woman who presented for evaluation of secondary infertility and recurrent pregnancy loss is described. Although one living child had been conceived without medical assistance, that delivery preceded the present evaluation by ten years and involved a different partner. With the current husband, the patient had two miscarriages and a left ectopic pregnancy. The couple had attempted controlled ovarian hyperstimulation and in vitro fertilization (IVF) elsewhere, but the cycle was cancelled due to poor follicular response. About one year before consultation at our institution, the couple established a pregnancy although the infant was born at 24 weeks with a cardiac anomaly, living only 40 days. Additionally, a persistent cervical lesion required cone biopsy before any fertility treatment could resume. Andrology evaluation found the husband's sperm DNA fragmentation index to be 48.6%. This constellation of stressors represented substantial emotional issues and psychological therapy/counseling was recommended. After obtaining psychological clearance, the couple underwent IVF and 16 oocytes were retrieved. Four embryos were transferred, and a healthy male infant was delivered at term. Although multifactorial infertility can be associated with very poor reproductive outcomes, the advanced reproductive technologies merit consideration during management of complex clinical challenges. Standard IVF strategies can be optimized by inclusion of thorough psychological assessment and counseling.

RESUMO

In order to describe potential hypofibrinolytic tendencies in young (< 35 years) polycystic ovary syndrome (PCOS) patients, we studied plasminogen activator inhibitor (PAI-1) system components in women without laboratory evidence of hyperinsulinism or hyperandrogenism. The study was a prospective, observational comparison and took place in a major urban infertility referral center. Age, body mass index, ovulatory status, selected androgen levels, fasting insulin and plasma lipids were measured in subjects with PCOS (n = 39) and normal control subjects (n = 20). Women with PCOS had higher mean serum total testosterone and androstenedione levels compared with controls (56.4 versus 40.3 ng/dl, p = 0.03, and 179 versus 133 microg/ml, p = 0.03, respectively). Mean fasting insulin levels were higher among PCOS women (p < 0.01) and were strongly correlated with PAI-1 antigen (Ag) (r = 0.46), PAI-1 activity (r = 0.43), and tissue plasminogen activator (t-PA) (r = 0.5). Correlations were evident in both PCOS and control subjects. Mean PAI-1 Ag, PAI-1 activity, and t-PA levels were significantly elevated (p = 0.003, 0.001, and 0.001, respectively) in PCOS. ANOVA was performed to control for insulin effect; a trend toward elevated PAI-1 in PCOS persisted but was no longer statistically significant (p = 0.24). PAI-1 activity elevation remained in PCOS women with mean fasting insulin levels < 10 mIU/ml (p = 0.02), yet the difference became less significant when insulin was controlled (p = 0.38). Although these data confirm known associations between insulin and PAI-1 derangements, this is the first study to quantify discrete PAI-1 elevations that persist in the setting of PCOS even with normal or low ambient insulin levels. Additional prospective studies are needed to determine whether this altered PAI-1 state is associated with a clinically important hypofibrinolytic condition and subsequent poor reproductive outcome.

RESUMO

A 39 year-old woman with previous salpingectomy developed a symptomatic heterotopic right cornual pregnancy identified by transvaginal ultrasonography at six weeks' gestation. The patient had previously undergone an ipsilateral partial salpingectomy, and the conception was established four months later after one cycle of controlled ovarian hyperstimulation, in vitro fertilization (IVF) and embryo transfer. We performed immediate surgical excision of the ectopic implantation with conservation of the intrauterine pregnancy. Progesterone was administered as 200 mg/d lozenge (troche) plus 200 mg/d rectal suppository, maintained from day of embryo transfer through the perioperative period and until 11th gestational week. Following an uneventful obstetrical course, a healthy male infant was delivered by cesarean at term. In this report, we review the incidence and significance of heterotopic gestation in the context of IVF/embryo transfer. Risk factors for complex intra- and extra-uterine pregnancies are also outlined. Additionally, the clinical management of heterotopic pregnancy, including a novel approach to progesterone supplementation, is discussed.

RESUMO

To compare standard density gradient centrifugation sperm preparation with a novel non-centrifugation-based dual-chamber capillary dish in efficiency for motile human sperm separation, approximately 3 mL fresh ejaculate specimens was obtained from 21 men (median age = 32 years. range 26-42 years) undergoing infertility evaluation. For each specimen, half of the sample was processed with a standard 45%/90% density gradient preparation (PureSperm. Nidacon International, Gothenburg, Sweden) followed by semen analysis. The other half was incubated in the Zech glass capillary dish (Astromedtec, Salzburg, Austria) consisting of 2 concentric wells overlaid by a U-ring and coverglass. After approximately 3 h, a 1-mL sample was taken from the central chamber and analyzed. Percentage motile sperm recovery, absolute (motile) cell number, and path velocities were compared for spermatozoa obtained from both methods. Both techniques reduced overall sperm concentration while enriching specimens with more motile spermatozoa. A trend towards higher % recovery of motile spermatozoa (p = .264) was observed with the Zech device, but at a cost of fewer absolute numbers of higher velocity cells (p = .004). The Zech device, therefore, localized a very small population of motile sperm without exposure to centrifugation stress, which has been considered potentially harmful to spermatozoa. This technique could theoretically improve efficiency by reducing time required to identify motile cells in in vitro fertilization where intracytoplasmic sperm injection is planned. However, refinements in incubation interval and suspension volumes are needed before this technique can be considered comparable to the density gradient method in recovering sperm for use in intrauterine insemination.

RESUMO

Etanercept (Enbrel; Wyeth-Ayerst/Immunex Inc, Seattle, WA, USA) is a subcutaneously administered novel fusion protein consisting of the extracellular ligand-binding domain of the 75 kD receptor for tumor necrosis factor-alpha (anti-TNFalpha) and the Fc portion of human IgG1. The agent is synthesized by plasmid transfection of a Chinese hamster ovary cell line, utilizing recombinant DNA technology. Etanercept was approved by the US FDA for treatment of multi-drug resistant rheumatoid arthritis in 1998, but no human data exist regarding the impact of anti-TNFalpha therapy on human reproductive function or its use before ovulation induction. As TNFalpha potentiates collagenolysis via matrix metalloproteinase gene expression (thereby facilitating ovulation), there exists a theoretical risk that TNFalpha-inhibition could exert an undesirable effect on ovulation and pregnancy. In this report, we describe the first case of ovulation induction, intrauterine insemination, normal pregnancy and singleton delivery of a healthy infant following chronic ( > 1 year) pre-ovulatory TNFalpha-inhibitor therapy for rheumatoid arthritis. Reproductive endocrinologists and obstetrician-gynecologists should be familiar with etanercept therapy in the context of severe rheumatic disease, and offer appropriate reassurance regarding its safe use for infertility patients planning ovulation induction.

RESUMO

OBJECTIVE: To describe serum levels of human chorionic gonadotropin (hCG) as a function of hCG injection method (subcutaneous vs. intramuscular) among infertile women undergoing ovulation induction. DESIGN: Prospective, randomized clinical trial. SETTING: Major urban infertility referral center. PATIENT(S): Women presenting for infertility evaluation and ovulation induction. INTERVENTION(S): Controlled ovarian hyperstimulation was followed by 5,000 IU urinary (nonrecombinant) hCG injection, given intramuscularly (i.m.) or subcutaneously (s.c.). MAIN OUTCOME MEASURE(S): Serum hCG levels measured 24 hours after administration of hCG, and patient tolerability of injected hCG. RESULT(S): There were no statistically significant differences in age or body mass index (BMI) among patients receiving hCG s.c. (n = 13) or i.m. (n = 15). Mean [IQR (25; 75)] serum hCG levels in the s.c. and i.m. groups were 171.7 [27.0; 207.0] and 142.2 [102.5; 157.5] mIU/mL, respectively. No adverse events were registered by any patient receiving hCG by either injection method. In this non-IVF population, two pregnancies were established in each subgroup (4 of 28, or approximately 14% pregnancy rate). CONCLUSION(S): The s.c. administration of 5,000 IU hCG (reconstituted in vol. = 0.5 mL) was well tolerated by all women in this study and was associated with postinjection serum hCG levels similar to those observed after administration of an equivalent i.m. hCG dose. This investigation suggests that clinical use of s.c. hCG is suitable for lean women (e.g., BMI <30) undergoing ovulation induction, but additional data are needed to study the appropriateness of s.c. hCG administration in heavier patients.

RESUMO

The present study presents an atlas of the effects of 10 kHz tone exposures of different levels and durations on cochlear hair cells and their stereocilia in the Syrian golden hamster. Animals were sound exposed while under anesthesia. The exposure conditions were varied over an intensity range of 90-129 dB SPL; at the highest levels (126-129 dB SPL) the exposure periods were varied over a range of 30 min to 4 h. In animals with mild damage the lesions were commonly restricted to either the inner hair cells and/or the first row of outer hair cells; the order of damage susceptibility was IHC, OHC1, OHC2, OHC3. Damage to the second and third rows of outer hair cells were found only in animals with the severest lesions. Possible mechanisms underlying the row-specific distributions of these lesions and relative susceptibilities of the 4 rows of hair cells are discussed.

RESUMO

Hamsters were exposed to intense tones (10 kHz) at levels and durations sufficient to cause stereocilia lesions. The purpose was to determine how the tonotopic map of the dorsal cochlear nucleus (DCN) readjusts to loss of receptor sensitivity. Neural population thresholds and tonotopic organization was mapped over the surface of the DCN in normal unexposed animals and those showing tone-induced lesions. The results indicate that cochlear lesions characterized mainly by loss of stereocilia in a restricted portion of the organ of Corti cause changes in a corresponding region of the tonotopic map which reflect primarily changes in the shape and thresholds of neural tuning curves. In many cases the center of the lesion was represented in the DCN as a distinct characteristic frequency (CF) gap in the tonotopic map in which responses were either extremely weak or absent. In almost all cases the map area representing the center of the lesion was bordered by an expanded region of near-constant CF, a feature superficially suggestive of map reorganization. These expanded map areas had abnormal tip thresholds and showed other features suggesting that their CFs had been shifted downward by distortion and deterioration of their original tips. Such changes in neural tuning are similar to those observed by others in the auditory nerve following acoustic trauma, and thus would seem to have a peripheral origin. Thus, it is not necessary to invoke plastic changes in the cochlear nucleus to explain the changes observed in the tonotopic map.

RESUMO

Hyperprolactinemia, a known modulator of reproductive function, occurs commonly in women undergoing ovarian stimulation with human menopausal gonadotropins (hMG). Clomiphene citrate (CC) and gonadotropin releasing hormone analogues (GnRHa), when administered during the luteal phase, attenuate the hyperprolactinemic response to hMG. We asked whether follicular-phase administration of CC and GnRHa, as employed clinically in women undergoing ovarian stimulation for in vitro fertilization or gamete intrafallopian transfer, would alter the incidence and severity of hMG-induced luteal-phase hyperprolactinemia. Seventy-five percent of all patients had at least one luteal prolactin level greater than 25 ng/ml, and 40% had mean luteal-phase prolactin levels greater than 25 ng/ml. The incidence of hyperprolactinemia was similar in pregnant and nonpregnant cycles. The incidence of hyperprolactinemia was similar for both the GnRH agonist-treated group and those given clomiphene citrate. The increase in mean luteal prolactin levels over the follicular-phase baseline level was significantly greater in the CC-treated group (P = 0.03). This was due to the significant suppression of follicular-phase baseline prolactin levels in patients receiving CC. We conclude that neither CC nor GnRHa administration in the follicular phase prevents luteal-phase hyperprolactinemia in women undergoing ovarian stimulation with hMG.

RESUMO

Superovulation with intrauterine insemination (SO-IUI) has been suggested as an alternative to gamete intrafallopian transfer (GIFT), despite the absence of controlled or comparative trials. We retrospectively analyzed all GIFT and SO-IUI cycles performed concurrently from January 1985 to August of 1987 at a single university center. Pregnancy rates were significantly better for GIFT than SO-IUI (P less than 0.001), with an odds ratio of 3.25 (P = 0.001). Stepwise multiple logistic regression identified factors that correlate with pregnancy: absence of endometriosis (P = 0.05), infertility less than 3 years' duration (P = 0.002), TMS greater than or equal to 30 X 10(6) (P = 0.005), and treatment with GIFT rather than SO-IUI (P = 0.001). These data give a first approximation of the increased efficacy of GIFT versus SO-IUI and provide valuable insight into significant confounding variables to be considered when planning a randomized, prospective trial to evaluate these techniques.

RESUMO

To study the relationship between endometriosis and ovulatory dysfunction, we induced ovarian endometriosis in the rabbit model Adipose tissue was placed in the contralateral ovary as a control. Ovulation was induced with human chorionic gonadotropin, and ovulation points were counted before and after induction of endometriosis. Periovarian adhesions were graded, and ovaries were histologically examined. A significant decrease in the number of ovulation points was observed in ovaries with endometrial tissue (p = 0.001) but not in ovaries that contained adipose tissue (p = 0.095). Periovarian adhesions decreased the number of ovulation points (p less than 0.01) in ovaries that contained adipose or endometrial tissues. Multivariate analysis demonstrated that an increase in adhesion severity was correlated with a decrease in the number of ovulation points (p less than 0.05), but endometrial tissue was not (p = 0.45). We conclude that, in the rabbit model, minimal ovarian endometriosis impairs ovulation primarily through a mechanism related to periovarian adhesions.
