====Intrauterine insemination (IUI)====
*'''Technique'''
**'''<span style="color:#ff0000">Involves processing a semen specimen and placing the low volume washed semen into the uterine cavity at the time of ovulation'''
**May be done with or without ovarian stimulation of the female partner to enhance oocyte production
***Pregnancy rates with IUI are increased in couples with abnormal semen parameters if the woman undergoes ovulation induction.
****In men with male factor infertility due to abnormal semen parameters, natural cycle intracervical or intrauterine insemination (IUI) is no better than timed vaginal intercourse.
*****Natural cycle refers to allowing the woman to ovulate on her own without pharmaceutical induced stimulation of the development of multiple follicles through ovulation induction.
*****Natural cycle IUI is useful in infertility caused by mechanical problems such as hypospadias, retrograde ejaculation, impotence, or pure cervical factor infertility.
*'''Males with low total motile sperm count (<5 million motile sperm after processing) are expected to have lower pregnancy rates after IUI than using sperm from men with normal total motile sperm counts.[https://pubmed.ncbi.nlm.nih.gov/33295257/ ★]'''
**Since approximately 50% of sperm do not survive semen processing, a total motile count of at least 5 to 10 million sperm is usually required to allow for an adequate number of motile sperm for insemination.[https://pubmed.ncbi.nlm.nih.gov/33295257/ §]
