Editing Retrograde ejaculation (section)

=== Infertility treatments ===
If a couple is experiencing [[infertility]] as a result of retrograde ejaculation and medications are not helping, the collection of the semen collection may undergo a special procedure. First, the patient alkalinizes his urine by intake of sodium bicarbonate (3g dissolved in water in the evening before bed, and then another dose after complete bladder emptying  right before going to the laboratory). Before semen collection the patient must empty his bladder. The patient then has to masturbate in one container and immediately after has to urinate in another container.<ref>{{Cite journal|last=Mehta|first=Akanksha|last2=Sigman|first2=Mark|date=November 2015|title=Management of the dry ejaculate: a systematic review of aspermia and retrograde ejaculation|journal=Fertility and Sterility|volume=104|issue=5|pages=1074–1081|doi=10.1016/j.fertnstert.2015.09.024|pmid=26432530|issn=0015-0282|doi-access=free}}</ref> The male's ejaculate may be [[centrifuge]]d from urine voided, and the isolated sperm injected directly into the woman through the use of [[intrauterine insemination]].<ref name="merck" /> In more severe cases, [[in-vitro fertilization]] with [[intracytoplasmic sperm injection]] may be used.<ref name="fertilityfactor">[http://www.fertilityfactor.com/infertility_male_infertility_retrograde_ejaculation.html Retrograde ejaculation treatments] Infertility factors portal.
