影響人工受孕ㄉ成功率最重要ㄉ男性因素
影響人工受孕ㄉ成功率最重要ㄉ男性因素為總活動精蟲數total motile sperm (TMC)
較低的授精 TMC 與活產率降低有關，
較高的 TMC 與較高的活產率相關（TMC 1500-2000 萬（14.8%）相比≤500 萬（5.5%）
而從hCG注射到IUI的時間、精子製備方法和IUI超音波引導與成功率無關。
Intrauterine insemination performance characteristics and post-processing total motile sperm count in relation to live birth for couples with unexplained infertility in a randomised, multicentre clinical trial
Human Reproduction, Volume 35, Issue 6, June 2020, Pages 1296–1305,
lower inseminate TMC were associated with a reduced live birth rate,
while time from hCG injection to IUI, sperm preparation method and ultrasound guidance for IUI were not associated with live birth success.
Time from hCG trigger injection to IUI was not significantly associated with outcome.
Higher TMC was associated with greater live birth rate (TMC 15.1–20.0 million (14.8%) compared to ≤5 million (5.5%)) (aRR 2.09 (1.31–3.33)). However, live births did occur with TMC ≤ 1 million (5.1%).
Higher TMC inseminated leads to an increase in live birth rate up to TMC ~20 million
