Since mother to child transmissions of hepatitis C virus (HCV) have been reported to be low, teams involved in assisted reproductive technologies have accepted HCV positive patients into their programmes. We report in the present paper two cases of undoubted patient to patient HCV transmission while patients were attending for assisted conception. In both cases, HCV genotyping and sequencing of the first hypervariable region of the HCV genome provided molecular evidence for nosocomial transmission. Investigations made to elucidate the route of contamination have shown that the most likely route of contamination is through healthcare workers. Such nosocomial HCV infection has been reported in other healthcare situations, mainly in dialysis units, and physical proximity was also suspected to be at the origin of the infection. We conclude that assisted reproduction teams must be very prudent when including such patients in their programmes.

This study aimed to integrate clinical and biological parameters in a score able to predict ovarian response to stimulation for IVF in gonadotrophin-releasing hormone (GnRH) antagonist protocols. A progressive discriminant analysis to establish a score including the main clinical and biological parameters predicting ovarian response was performed by retrospectively analysing data from the first ovarian stimulation cycle of 494 patients. The score was validated in a prospectively enrolled, independent set of 257 patients undergoing their first ovarian stimulation cycle. All ovarian stimulations were performed using a combination of GnRH antagonist and recombinant FSH. Ovarian response was assessed through ovarian sensitivity index (OSI). Parameters from the patients' database were classified according to correlation with OSI: the progressive discriminant analysis resulted in the following calculation: score = 0.192 - (0.004 × FSH (IU/l)) + (0.012 × LH:FSH ratio) + (0.002 × AMH (ng/ml)) - (0.002 × BMI (kg/m)) + (0.001 × AFC) - (0.002 × age (years)). This score was significantly correlated with OSI in the retrospective (r = 0.599; P < 0.0001) and prospective (r = 0.584; P < 0.0001) studies. In conclusion, the score including clinical and biological parameters could explain 60% of the variance in ovarian response to stimulation.

Objective To evaluate the impact of age-specific anti-Mullerian (AMH) levels on the cumulative live birth rate after 4 intra uterine inseminations (IUI). Study Design The retrospective study study involved 509 couples who underwent their first IUI between January 2011 and July 2017 in the Toulouse University Hospital. All IUI were performed after an ovarian stimulation combining recombinant FSH and GnRH antagonist. The main measure outcome was the cumulative live birth rate (LBR) defined as the number of deliveries with at least one live birth resulting from a maximum of 4 IUI attempts. Results When compared to normal or high levels, low age-specific AMH (<25th of the AMH in each age group) was associated to a non-significant lower live birth rate (31%, 38% and 42% respectively for low, normal and high age-specific groups; P = 0.170) and non-significant higher miscarriage rate (26%; 19% and 14% respectively for low, normal and high age-specific groups; P = 0.209). However, it must be pointed out that in low age-specific AMH the initial FSH doses used for stimulation were higher than in the other groups. Conclusion This study shows that the age-specific levels of AMH have only a slight effect on IUI outcome when adapting the stimulation protocols to their level.

The aim of the present study was to compare conventional and computer-assisted morphology assessment of spermatozoa. Sixty-two semen samples from patients undergoing in vitro fertilization (IVF) and 40 samples from patients undergoing an intracytoplasmic sperm injection (ICSI) were studied using both techniques. The percentage of normal spermatozoa found was closely correlated between the techniques (r=0.788, p < 0.0001). The intra-operator variation was low for both techniques but the inter-operator variation was much higher with the conventional than with the computer-assisted method (coefficient of variation = 0.43 vs. 0.08, respectively, for conventional and computer-assisted assessments). The percentage of spermatozoa with normal morphology, as well as sperm motility, was significantly enhanced after PureSperm preparation, whatever the method used for assessment. In the IVF study, fertilization rate was poorly correlated with sperm morphology using both methods. However, combined with motility, morphology assessed with the computer allowed discrimination of two groups of patients with significantly different fertilization rates (30.5 +/- 5.4% vs. 63.1 +/- 5.4%, p < 0.0001). In contrast, the fertilization rate in ICSI was influenced neither by sperm morphology nor by motility. In conclusion, computer-assisted assessment of sperm morphology has a slightly better predictive value for ART than conventional assessment, but above all is much more reproducible, allowing standardization.

A total of 101 patients with one normal tube were compared with 117 patients with two normal tubes to assess the effect of unilateral tubal abnormalities on the results of intrauterine inseminations. The clinical pregnancy and live birth rates seemed to reduce by one-half in almost all types of abnormality, suggesting that these patients should be preferentially treated with IVF.

(Abstracted from Reprod Biomed Online 2017;35:314–317) While intrauterine insemination (IUI) is one of the first lines of infertility treatments and assisted reproductive techniques, the mean delivery per insemination rate is 10.7% and varies widely from one center to another, according to the French registry. This variation could be attributed to the heterogeneity of the treated population, especially with regard to fallopian tube status.
