Impact of government health coverage for ART: The results of a 5-year experience in Quebec.

An analysis of national registry data for 5 years of in-vitro fertilization (IVF) funding in Quebec, Canada was compared with the previous complete year of non-funded IVF cycles, as well as the first complete year following the end of funding. The number of cycles, livebirth rates, age group of patients treated, use of donor gametes, multiple pregnancy rates and cycle cancellation rates were assessed. The total number of IVF cycles performed increased dramatically during the funded period, averaging over 10,000 cycles per year. There was no change in the age group distribution of patients treated, but less egg donation was performed. Interestingly, funding was also associated with an increase in the IVF cycle cancellation rate (17.0% versus 34.4%, P < 0.001), a dramatic decline in the multiple pregnancy rate (25.6% versus 4.9%, P < 0.001), and a decline in the livebirth rate per fresh embryo transfer in stimulated IVF cycles (32.3% versus 25.5%, P < 0.001). Although the livebirth rate for stimulated IVF declined, over 9000 babies were born as a result of the coverage. Lessons learned from this experience could help develop a more fiscally responsible programme that still facilitates access to IVF care.

ICSI outcomes using testicular spermatozoa in non-azoospermic couples with recurrent ICSI failure and no previous live births.

BACKGROUND: The use of testicular over ejaculated spermatozoa for ICSI has been presented as an alternative to overcome infertility in men with poor semen parameters or high levels of sperm DNA fragmentation. OBJECTIVE: To evaluate the efficacy of testicular ICSI outcomes in couples with no previous live birth and recurrent ICSI failure using ejaculated spermatozoa by comparison to the outcomes of couples with similar history of recurrent ICSI using ejaculated spermatozoa only. MATERIALS AND METHODS: A total of 145 couples undergoing ejaculated or testicular ICSI cycles with no previous live births and with at least two previous failed ICSI cycles with ejaculated spermatozoa were evaluated retrospectively. ICSI was performed either with ejaculated (E-ICSI) or with testicular (T-ICSI) spermatozoa. Semen parameters and sperm DNA quality were assessed prior to the oocyte collection day. Primary outcomes included cumulative live birth and pregnancy rates. Secondary analysis included percentage of DNA fragmentation in ejaculated spermatozoa (SCSA® and TUNEL). RESULTS: Patients undergoing T-ICSI (n = 77) had a significantly higher clinical pregnancy rate/fresh embryo transfer (ET) (27.9%; 17/61) and cumulative live birth rate (23.4%; 15/64) compared to patients using E-ICSI (n = 68) (clinical pregnancy rate/fresh ET: 10%; 6/60 and cumulative live birth rate: 11.4%; 7/61). Further, T-ICSI yield significantly better cumulative live birth rates than E-ICSI for men with high TUNEL (≥36%) (T-ICSI: 20%; 3/15 vs. E-ICSI: 0%; 0/7, p < 0.025), high SCSA® (≥25%) scores (T-ICSI: 21.7%; 5/23 vs. E-ICSI: 9.1%; 1/11, p < 0.01), or abnormal semen parameters (T-ICSI: 28%; 7/25 vs. E-ICSI: 6.7%; 1/15, p < 0.01). CONCLUSIONS: The use of testicular spermatozoa for ICSI in non-azoospermic couples with no previous live births, recurrent ICSI failure, and high sperm DNA fragmentation yields significantly better live birth outcomes than a separate cohort of couples with similar history of ICSI failure entering a new ICSI cycle with ejaculated spermatozoa.

Does using testicular sperm retrieval rather than ejaculated spermatozoa improve reproductive outcomes in couples with previous ART failure and poor ovarian response? A case-controlled study.

The objective of this study was to assess whether testicular-retrieved spermatozoa improve reproductive outcomes compared to fresh ejaculate in women with poor ovarian response and a history of previous ART failure. The study was performed as a retrospective case-control study at a university-based reproductive center in Montreal, Quebec, Canada. Eighteen poor-responder patients were matched 3 : 1 with 54 controls. Poor responders were defined as those with ≤3 oocytes retrieved at oocyte pickup. Cases were identified as poor responders, and only those with previous IVF failure(s) as an indication for testicular-retrieved spermatozoa were included. Controls were age and cycle attempt number matched. All patients were included only once. From January 1, 2009 to December 31, 2015, all patients and controls underwent an IVF cycle using ICSI with either testicular spermatozoa or ejaculated spermatozoa, respectively. Outcomes included live birth rate, pregnancy rate, miscarriage rate, oocyte number, and embryo transfer (ET) day. The results showed live birth rates, pregnancy rates, and miscarriage rates were similar. There were fewer day 2 ETs (8.5% vs. 48.6%, p = 0.01) and more day 5 blastocyst transfers (25.0% vs. 5.4%, p = 0.05) in the testicular sperm retrieval group compared to controls and thus an overall suggestion of better embryo quality in the testicular sperm group. Overall, however, the use of testicular sperm retrieval appears to add little. Women with poor ovarian response typically have a poor prognosis with respect to live birth rates, and this is further supported in this study. The suggestion of better embryo quality in the testicular-retrieved sperm group would need to be further assessed in a larger multicentered study.

The relationship between fat and progesterone, estradiol, and chorionic gonadotropin levels in Quebec cow's milk.

PURPOSE: The majority of milk in industrialized countries is obtained from pregnant cows, which contains increased levels of estrogen and progesterone compared to non-pregnant cows. The aim of this study was to quantify the amount of hormones present in milk with different fat content because previous studies on humans have shown potential effects of increased milk consumption on serum and urine hormone levels as well as on sperm parameters. However, it is unclear whether consumption of milk at the currently recommended levels would lead to systemic effects. METHODS: Samples of cow's milk of varying fat concentrations (0, 1, 2, 3.25, 10, and 35%) were analyzed via competitive ELISA assays. RESULTS: Progesterone concentrations were significantly correlated to increasing fat content of milk (r = 0.8251, p = 0.04). CONCLUSIONS: Research on conditions in which additional progesterone may have an effect on human health should consider inclusion of limitation of milk intake and its effects. Further studies are needed to determine the concentration of progesterone in milk of different fat content in other regions and countries and to quantify the potential pathophysiologic role.

Quebec public funding facilitates fertility preservation for male cancer patients.

BACKGROUND: Sperm cryopreservation remains the only clinically feasible option to preserve male fertility. The quality of counselling provided by the treating physicians and the cost of sperm cryopreservation can both influence a patient's decision about whether to preserve sperm. On 5 August 2010, the Quebec government introduced provincial coverage of assisted reproductive technologies, with sperm cryopreservation included as a covered service. The aim of the present study was to evaluate whether and how such a program affects the behaviour of cancer patients with respect to sperm cryopreservation. METHODS: We analyzed the database derived from male patients undergoing sperm cryopreservation from August 2008 to August 2012 at our centre. The retrieved data included patient age, male infertility or oncologic diagnosis, sperm quality parameters, and details about the number of visits for sperm cryopreservation. RESULTS: The number of cancer patients who cryopreserved sperm before and after the policy change did not differ significantly, but a marked increase in the number of non-cancer patients was observed. Further analysis revealed that, after implementation of the public funding program, the total number of sperm cryopreservation sessions per patient increased significantly in cancer patients but not in non-cancer patients. CONCLUSIONS: It appears that cancer patients who are willing to freeze sperm are keen to return for more sessions of sperm banking when no fees are associated with the service. Those findings suggest that cost reduction is an important factor for improving delivery of fertility preservation services to male cancer patients.

A national study of the provision of oncology sperm banking services among Canadian fertility clinics.

The purpose of this study was to survey the current state of oncology sperm banking services provided by fertility clinics across Canada. A total of 78 Canadian fertility facilities were invited to complete a questionnaire related to the availability, accessibility, affordability and utilisation of sperm banking services for cancer patients. The total response rate was 59%, with 20 (69%) in vitro fertilisation clinics and 26 (53%) other fertility centres returning the survey. A total of 24 responding facilities accepted oncology sperm banking referrals. The time frame to book the first banking appointment for 19 (79%) facilities was within 2 days. Inconsistent practice was found regarding the consent process for cancer patients who are of minority age. Eight (33%) facilities did not provide any subsidy and charged a standard banking fee regardless of patients' financial situations. Overall, the utilisation of oncology sperm banking services was low despite its availability and established efficacy, suggesting that Canadian cancer patients are notably underserved. The study has highlighted some important issues for further consideration in improving access to sperm banking services for cancer patients, especially for adolescents. Better collaboration between oncology and reproductive medicine to target healthcare providers would help to improve sperm banking rates.

Excisional surgery versus ablative surgery for ovarian endometriomata.

BACKGROUND: Endometriomata are endometriotic deposits within the ovary. The surgical management of these blood filled cysts is controversial. The laparoscopic approach to the management of endometriomata is favoured over a laparotomy approach as it offers the advantage of a shorter hospital stay, faster patient recovery and decreased hospital costs. Currently the commonest procedures for the treatment of ovarian endometriomata are either excision of the cyst capsule or drainage and electrocoagulation of the cyst wall. OBJECTIVES: The objective of this review was to determine the most effective technique of treating an ovarian endometrioma; either excision of the cyst capsule or drainage and electrocoagulation of the cyst wall. The end-points assessed were the relief of pain, recurrence of the endometrioma, recurrence of symptoms and in women desiring to conceive the subsequent pregnancy rate, either spontaneous or as part of fertility treatment. SEARCH STRATEGY: The reviewers searched the Cochrane Menstrual Disorders and Subfertility Group specialised register of trials (searched 3rd March 2007), the Cochrane Register of Controlled Trials (The Cochrane Library, Issue 3, 2007), MEDLINE (1966-August 2007), EMBASE (1980- March 2007) and reference lists of articles, the handsearching of relevant journals and conference proceedings and by contacting leaders in the field of endoscopic surgery throughout the world. The Cochrane Menstrual Disorders and Subfertility Group Trials Register is based on regular searches of MEDLINE, EMBASE, CINHAL and CENTRAL. SELECTION CRITERIA: Randomised controlled trials of excision of the cyst capsule versus drainage and electrocoagulation of the cyst in the management of ovarian endometriomata. DATA COLLECTION AND ANALYSIS: Reviewers assessed eligibility and trial quality. MAIN RESULTS: No randomised studies of the management of endometriomata by laparotomy were found. Two randomised studies of the laparoscopic management of ovarian endometriomata of greater than 3cm in size, for the primary symptom of pain were included. Laparoscopic excision of the cyst wall of the endometrioma was associated with a reduced recurrence rate of the symptoms of dysmenorrhea (OR 0.15 CI 0.06-0.38), dyspareunia (OR 0.08 CI 0.01-0.51) and non-menstrual pelvic pain (OR 0.10 CI 0.02-0.56), a reduced rate of recurrence of the endometrioma (OR 0.41 CI 0.18-0.93) and with a reduced requirement for further surgery (OR 0.21 CI 0.05-0.79) than surgery to ablate the endometrioma. For those women subsequently attempting to conceive it was also associated with a subsequent increased spontaneous pregnancy rate in women who had documented prior sub-fertility (OR 5.21 CI 2.04-13.29). A further randomised study was identified that demonstrated an increased ovarian follicular response to gonadotrophin stimulation for women who had undergone excsional surgery when compared to ablative surgery (WMD 0.6 CI 0.04-1.16). There is insufficient evidence to favour excisional surgery over ablative surgery with respect to the chance of pregnancy after controlled ovarian stimulation and intra-uterine insemination (OR 1.40 CI 0.47-4.15) . AUTHORS' CONCLUSIONS: There is good evidence that excisional surgery for endometriomata provides for a more favourable outcome than drainage and ablation with regard to the recurrence of the endometrioma, recurrence of pain symptoms, and in women who were previously subfertile, subsequent spontaneous pregnancy . Consequently this approach should be the favoured surgical approach. However in women who may subsequently may undergo fertility treatment insufficient evidence exists to determine the favoured surgical approach.

Ultrasound versus 'clinical touch' for catheter guidance during embryo transfer in women.

BACKGROUND: Many women undergoing an Assisted Reproductive Technology (ART) cycle will not achieve a live birth. Failure at the embryo transfer stage may be due to poor embryo quality, lack of uterine receptivity, or the transfer technique itself. Numerous methods, including the use of ultrasound guidance for proper catheter placement in the endometrial cavity, have been suggested as a means of improving the technique of embryo transfer. This review evaluates the effectiveness of ultrasound (UGET) in comparison with 'clinical touch' embryo transfer (CTET) the traditional method of embryo transfer. OBJECTIVES: :To determine whether ultrasound guidance influences treatment outcomes in women undergoing embryo transfer (ET) during assisted reproductive technology (ART) cycles. SEARCH STRATEGY: All electronic databases were searched on 20 th August 2006. We searched the Cochrane Menstrual Disorders and Subfertility Group trials register (searched August 2006), the Cochrane Central Register of Controlled Trials (The Cochrane Library, Issue 1, 2006), MEDLINE (1970-2006), EMBASE (1985-2006), BIO Extracts (1980-2006). Relevant conference proceedings were also hand searched (ASRM, ESHRE and FIGO). SELECTION CRITERIA: Only randomised controlled trials were included. DATA COLLECTION AND ANALYSIS: Two reviewers independently assessed eligibility and quality of trials and extracted data from those selected. MAIN RESULTS: Thirteen out of fifteen identified studies were eligible for analysis. No study reported live births, however, personal communication resulted in data relating to this outcome being obtained in two of the studies. Six studies reported on ongoing pregnancies. The live birth/ ongoing pregnancies per woman randomised associated with UGET (452/1376) was significantly higher than for clinical touch (353/1338) OR 1.40, 95%CI 1.18 to 1.66, P<0.0001). This means, for example, that for a population of women with a 25% chance of pregnancy using clinical touch this would be increased to 32% (28% to 46%) by using UGET. There were no statistically significant differences in the incidence of adverse events between the two comparison groups with the exception of blood on the catheter. AUTHORS' CONCLUSIONS: The studies are limited by their quality with only one of the thirteen studies reporting details of both computerised randomisation techniques and adequate allocation concealment. Ultrasound guidance does appear to improve the chances of live/ongoing and clinical pregnancies compared with clinical touch methods. The quality of future studies should be improved with adequate reporting of randomisation, allocation concealment, and power calculations. The primary outcome measure of future studies should be the reporting of live births per woman randomised.

Consequently this approach should be the favoured surgical approach. However we found no data as to the effect of either approach in women who subsequently undergo assisted reproductive techniques.

The cryobiology of assisted reproduction.

Cryopreservation of human gametes and embryos has become an integral part of assisted reproduction. The major developments in cryopreservation technology have mirrored the rapid expansion of reproductive technology over the past 2 decades. It is now possible to cryopreserve sperm, oocytes and embryos at their various stages of development. The introduction of vitrification and rapid freezing techniques is gaining widespread recognition and may become the method of choice over traditional slow freezing methods. Ovarian tissue cryopreservation offers the hope of fertility preservation for women who are faced with potentially sterilizing medical or surgical treatments. Paralleling the introduction of cryobiology to assisted reproduction has been the realization of a number of moral and ethical issues related to gamete and/or embryo storage.

Fructose concentrations in seminal plasma from men with nonobstructive azoospermia.

Fructose is secreted from the seminal vesicles and the accessory sex glands. It is the major carbohydrate source in seminal plasma and essential for normal sperm motility. The objective of this prospective descriptive study was to measure fructose concentrations in seminal plasma from men with obstructive and non-obstructive azoospermia, as determined by serum FSH, and to compare these with fructose concentrations in seminal plasma from men with normal semen parameters. A higher median fructose concentration was observed in seminal plasma from men with azoospermia and a raised serum FSH (3.22 mg/ml) compared to that from men with azoospermia and normal serum FSH (2.30 mg/ml) (p < 0.0001) and to that from normal controls (2.50 mg/ml) (p < 0.0002). This is the first report of increased seminal plasma concentrations of fructose in samples from men with non-obstructive azoospermia. This is either due to a decreased fructose metabolism associated with the azoospermia or, more likely, an increased fructose production from the seminal vesicles.

Pregnancy and delivery after cryopreservation of zygotes produced by in-vitro matured oocytes retrieved from a woman with polycystic ovarian syndrome.

This case report describes the birth of a healthy infant after cryopreservation of zygotes produced by in-vitro matured oocytes retrieved from an anovulatory woman with polycystic ovarian syndrome (PCOS). To initiate the treatment cycle, the patient received intravaginal progesterone at night for 10 days to induce a withdrawal bleed. Oocyte retrieval was performed on day 11 following a withdrawal bleed. The patient was administered 10,000 IU of HCG subcutaneously 36 h prior to oocyte collection. A total of 63 immature oocytes were obtained; 10 were morphologically abnormal. Following incubation for 24--48 h in the maturation medium, TC-199 supplemented with 20% patient's own serum, 75 mIU/ml FSH and LH, 77.4% (41/53) of the oocytes were at the metaphase-II stage. Thirty-one (31/41, 75.6%) were fertilized using ICSI with her husband's spermatozoa, 15 fertilized oocytes were cultured for embryo transfer and 16 were frozen at the pronuclear stage. Pregnancy ensued following fresh embryo transfer. Unfortunately, the pregnancy was miscarried eight weeks later. However, the second frozen-thawed embryo transfer attempt resulted in a full-term pregnancy with delivery of a healthy male infant.

Impact of reducing the number of embryos transferred from three to two in women under the age of 35 who produced three or more high-quality embryos.

OBJECTIVE: To investigate the effect of a reduction in the number of good-quality embryos transferred in patients <35 years of age on pregnancy and multiple pregnancy rate. DESIGN: Prospective observational study with historical controls. SETTING: Academic tertiary referral unit. PATIENT(S): Three hundred eight patients <35 years of age undergoing IVF-ET. INTERVENTION(S): For patients who had three or more good quality embryos available for transfer, those in group 1 were given the option to have either two or three embryos replaced, whereas those in group 2 were allowed a maximum of two embryos transferred. In both groups, patients who had less than three good-quality embryos had the option to have three embryos transferred. MAIN OUTCOME MEASURE(S): Pregnancy and multiple pregnancy rates. RESULT(S): Patients in group 1, compared with those in group 2, had significantly more embryos (3 vs. 2) of significantly higher cumulative embryo score (31 vs. 24) transferred. This resulted in significantly higher multiple (57.8% vs. 30.8%) and triplet (15.6% vs. 1.4%) pregnancy rates in group 1. However, no difference in overall clinical pregnancy rate (37.2% vs. 41.2%) or live birth rate (28.1% vs. 29.4%) was observed between group 1 and 2. CONCLUSION(S): In women <35 years of age, who have three or more good-quality embryos available for transfer, a maximum of two embryos should generally be transferred.

The outcome of IVF-embryo transfer treatment in patients who develop three follicles or less.

Among 828 patients undergoing IVF-embryo transfer treatment, the implantation and pregnancy rates of patients who developed < or = 3 follicles were compared prospectively with those patients who had a normal response. Patients who developed 1 to 3 follicles during ovarian stimulation elected to proceed with oocyte collection, have intrauterine insemination if appropriate, or to have their cycle cancelled. In the group of patients who developed < or = 3 follicles and who were aged <40 years, despite a significantly lower number of oocytes collected [2 versus 7; median difference (MD) = 9; confidence interval (CI) = 7-11, and lower number of embryos developed and transferred (1 versus 3; MD = 2; CI = 1-2), no difference in either implantation rate [27.8 versus 20.4%; odds ratio (OR) = 1.58; CI = 0.46-4.54] or pregnancy rate (27.8 versus 36.7%; OR = 0.7; CI = 0.2-2.0) was noted when compared with similarly aged patients who developed >3 follicles. However, in patients aged >40 years who developed < or = 3 follicles, a moderate, albeit non-significant decrease in implantation rate (3.8 versus 7.8%; OR = 1.91; CI = 0.4-57.0) and pregnancy rate (4.2 versus 18.3%; OR = 1.92; CI = 0.38-57.0) was observed when compared with patients of a similar age who developed >3 follicles. Patients aged <40 years, unlike older patients, maintain good implantation and pregnancy rates despite a poor response to ovarian stimulation. This study indicates that for this group of women, continuation of IVF treatment is a better option than cancellation.

Prospective randomized study of human chorionic gonadotrophin priming before immature oocyte retrieval from unstimulated women with polycystic ovarian syndrome.

The present study examined whether the rates of oocyte maturation, fertilization and development, as well as pregnancy rate could be improved by human chorionic gonadotrophin (HCG) priming 36 h before immature oocyte retrieval in patients with polycystic ovarian syndrome (PCOS). Immature oocyte retrieval was performed on day 10-14 of the cycles and patients were randomly allocated either to be primed with 10 000 IU of HCG before the retrieval, or not primed. Immature oocytes were cultured for 24-48 h in TC-199 medium with 20% (v/v) inactivated fetal bovine serum (FBS) supplemented with 75 mIU/ml follicle stimulating hormone (FSH) and luteinizing hormone (LH). Intracytoplasmic sperm injection (ICSI) was performed in all mature oocytes and the resulting embryos were transferred on day 2 or 3 after ICSI. A total of 17 patients underwent 24 completed treatment cycles. Thirteen cycles were primed with HCG and 11 other cycles were not primed. The mean number of oocytes retrieved was comparable in the two groups (7.8 +/- 3.9 versus 7.4 +/- 5.2). The percentage of oocytes achieving maturation at 48 h was significantly higher (P < 0.05) in the HCG-primed group (84.3%, 86/102) than in the non-HCG-primed group (69.1%, 56/81). Oocyte maturation was hastened in the HCG-primed group. Following 24 h of culture, 78.2 +/- 7.1% of oocytes were matured in the HCG-primed group compared with 4.9 +/- 2.5% of oocytes in the non-HCG-primed group (P < 0.001). There were no significant differences in the rates of oocyte fertilization and cleavage in these two groups. There were five clinical pregnancies (38.5%) in the HCG-primed group, and three pregnancies (27.3%) in the non-HCG-primed group.

Pregnancies resulting from in vitro matured oocytes retrieved from patients with polycystic ovary syndrome after priming with human chorionic gonadotropin.

OBJECTIVE: To describe pregnancies that resulted from in vitro matured oocytes derived from two unstimulated, anovulatory patients with polycystic ovary syndrome after priming with hCG before oocyte retrieval. DESIGN: Case series. SETTING: McGill Reproductive Center, Royal Victoria Hospital, McGill University. PATIENT(S): Two women with polycystic ovary syndrome. INTERVENTION(S): Progesterone induction of a withdrawal bleeding episode. The administration of subcutaneous hCG 36 hours before oocyte retrieval in a natural menstrual cycle. In vitro maturation of immature oocytes, fertilization, and ET. Luteal support with oral estrogen and progesterone. MAIN OUTCOME MEASURE(S): Pregnancy outcome. RESULT(S): Two clinical pregnancies were confirmed after oocyte maturation in vitro, fertilization with intracytoplasmic sperm injection, and ET. CONCLUSION(S): The administration of hCG 36 hours before harvesting of immature oocytes may improve the maturational and developmental competence of the oocytes and the pregnancy rates of unstimulated patients with polycystic ovary syndrome.

Ovarian stromal echogenicity in women with normal and polycystic ovaries.

Since the widespread use of transvaginal ultrasound to diagnose polycystic ovary syndrome (PCOS), a cardinal feature has been shown to be the presence of a bright, highly echogenic stroma. This is usually assessed subjectively. The objective of this study was to determine whether ovarian stromal echogenicity when measured objectively actually differed between women with polycystic ovaries and those with normal ovaries. A total of 67 women underwent a detailed ultrasound assessment before considering assisted conception treatment. Ovarian morphology was assessed and total ovarian volume, stromal volume, peak stromal blood flow velocity and mean stromal echogenicity were measured. The stromal index (ratio of mean stromal echogenicity to mean echogenicity of the entire ovary) and total stromal echogenicity were also calculated. Ovarian volume, stromal volume, and stromal peak blood flow velocity were all significantly higher in ovaries from women with PCOS. There was no difference in the mean stromal echogenicity, although the stromal index was significantly greater in women with polycystic ovaries. The apparent subjective increase in stromal echogenicity in women with polycystic ovaries, as exemplified by the greater stromal index, is due to a combination of the increased volume of ovarian stroma and the significantly lower mean echogenicity of the entire ovary in these women.

In vitro fertilization and intracytoplasmic sperm injection pregnancies after successful transport of oocytes by airplane.

OBJECTIVE: To determine the feasibility of a transport IVF program involving air transportation of oocytes. DESIGN: Prospective cohort study. SETTING: Regional hospital (Hôpital de Chicoutimi) and University Infertility Center (McGill Reproductive Center, Montreal). PATIENT(S): The first series of patients referred for IVF or IVF and ICSI, for a variety of indications, who opted for inclusion in the transport IVF program. INTERVENTION(S): The IVF-ET with ovarian stimulation and oocyte collection at the peripheral unit and transport of the oocytes by airplane to the McGill Reproductive Center where IVF or ICSI was performed. MAIN OUTCOME MEASURE(S): Clinical pregnancy. RESULT(S): Seven couples, in the first series, underwent nine cycles of transport IVF treatment. Two also underwent ICSI. There were two clinical pregnancies. CONCLUSION(S): Transport IVF using air travel is possible and opens the possibility for this type of program to be implemented in large countries with scattered populations, such as the United States, Canada, and Australia.

The evaluation of the sperm migration test as a predictor for success with intrauterine insemination.

OBJECTIVE: The objective of this study was to prospectively evaluate the sperm migration test (SMT) as a discriminator in couples undergoing intrauterine insemination (IUI). PATIENTS AND METHODS: 261 couples underwent 797 IUI treatment cycles involving gonadotropin stimulation in the three year period. All had a diagnosis of unexplained infertility. All male partners underwent a repeat standard seminal analysis and SMT prior to the female partner undergoing controlled ovarian stimulation. RESULTS: Despite apparently normal seminal analyses before referral, in 22 samples the sperm concentration, motility or morphology were abnormal (WHO criteria). Of these, 20 couples underwent 109 cycles and achieved 2 pregnancies giving a pregnancy rate of 1.8% per cycle and a cumulative pregnancy rate of 10% per couple. From the remaining couples with normal seminal analyses, 71 had an SMT <5 million/mL and 168 had an SMT >5 million/mL. The suboptimal SMT group underwent 276 cycles (3.89 cycles per couple) and achieved 18 pregnancies giving a pregnancy rate of 6.5% per cycle and a cumulative pregnancy rate of 25.4%. The normal SMT group underwent 412 cycles (2.45 cycles per couple) and achieved 60 pregnancies giving a pregnancy rate of 14.6% per cycle and a cumulative pregnancy rate of 35.7%. CONCLUSIONS: We confirm that abnormal seminal analysis leads to poor pregnancy rates with IUI. However, an SMT <5 million/mL despite normal seminal analysis (WHO criteria) also leads to significantly worse pregnancy rates. We would recommend that prior to IUI, couples are screened using the SMT.
