Abstract
BACKGROUND: This study was designed to assess whether the use of ganirelix in women undergoing stimulated IUI could prevent the occurrence of premature LH rises and luteinization (LH+progesterone rises). METHODS: Women of infertile couples, diagnosed with unexplained or male factor infertility, were randomized to receive either ganirelix (n=103) or placebo (n=100) in a double-blind design. All women were treated with an individualized, low-dose rFSH regimen started on day 2-3 of cycle. Ganirelix (0.25 mg/day) was started if one or more follicles>or=14 mm were visualized. Ovulation was triggered by HCG injection when at least one follicle>or=18 mm was observed and a single IUI was performed 34-42 h later. The primary efficacy outcome was the incidence of premature LH rises (+/-progesterone rise). RESULTS: In the ganirelix group, four subjects had a premature LH rise (value>or=10 IU/l), one LH rise prior to the start of ganirelix and three LH rises during ganirelix treatment, whereas in the placebo group 28 subjects had a premature LH rise, six subjects prior to the start of placebo and 22 subjects during placebo treatment. The incidence of LH rises was significantly lower in ganirelix cycles compared to placebo cycles (3.9 versus 28.0%; P=0.003 for ITT analysis). When excluding subjects with an LH value>or=10 IU/l before the start of ganirelix/placebo the incidence of LH rises was also significantly lower in ganirelix cycles compared to placebo cycles (2.9 versus 23.4%; P=0.003 for ITT analysis). Premature luteinization (LH rise with concomitant progesterone rise>or=1 ng/ml) was observed in one subject in the ganirelix group and in 17 subjects in the placebo group of which three subjects had a premature spontaneous ovulation. Ongoing pregnancy rates per attempt were 12.6 and 12.0% for the ganirelix and placebo groups respectively. CONCLUSIONS: Treatment with ganirelix effectively prevents premature LH rises, luteinization in subjects undergoing stimulated IUI. Low-dose rFSH regimen combined with a GnRH antagonist may be an alternative treatment option for subjects with previous proven luteinization or in subjects who would otherwise require insemination when staff are not working.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
