Cumulative pregnancy rate. (A) Diagnosis. Male, Cervical, and Unexplained = normal cycles without endometriosis or tubal factor. Ovulatory Dysfunction = anovulatory, polycystic ovaries, or luteal insufficiency. Endometriosis = without tubal involvement. Tubal Factor = endometriosis with tubal involvement and tubal adhesions or unilateral tubal obstruction. Patients aged ≥38 years and cycles with total initial motile sperm count of <5 million or motility of <30% were excluded. (B) Age. Patients with endometriosis, tubal factor, and cycles with total initial motile sperm count of <5 million or motility of <30% were excluded. (C) Sperm characteristics. Donor = cryopreserved sperm with ≥30 million motile count. WHO Standard = ≥40 million total count, ≥50% progressive motility, 30% normal forms. IUI Threshold = less than WHO Standard but ≥5 million total motile sperm and ≥30% initial motility. <IUI Threshold = initial motile sperm count of <5 million or motility <30%. Patients aged ≥38 years and patients with tubal factor were excluded. (D) Follicle count. Patients aged ≥38 years, with tubal factor, and cycles with total initial motile sperm count of <5 million or motility of <30%, were excluded.
