Dr Riwa kuna njia nyingine nayo ni "sperm washing"...hebu ielezee kitaalamu kwa njia nyepesi ili wengi wafaidike na ujuzi.
Ahsante da Tausi Mzalendo for bringing this up....'Sperm Washing' inatumia the same phenomenal kama IVF, that VVU wapo kwenye maji maji ya shahawa (seminal fluid) na sio kwenye mbegu (sperm cell). Kinachofanyika ni kuwa...mwanaume anajichua anatoa shahawa, halafu inatumika technique kama ya kwenye IVF kuseparate sperm cells from seminal fluid...ila badala ya kuharvest yai kama inavyofanyika kwenye IVF...hapa zile mbegu zilizooshwa humwagwa kwenye uke wa mwanamke ambaye yuko kwenye siku za kupata uja-uzito (danger days...sipendi kuziita hivi), na mwanamke anabeba mimba kama kawaida.
NB: Bado hii haijathibitishwa kisayansi kabisa kuwa haina risk kabisa, japo tafiti nyingi zimeshafanyika...bado tafiti zaidi zinahitajika (rejea article niliambatanisha hapo chini). Wasiwasi ni kuwa....japo vijidudu vya VVU haviko kwenye sperm cells, lakini vinaweza infect cells nyingine kwenye shahawa ukiacha sperm cells, na wakati wa 'sperm washing', hizi cell nyingine ambazo zinaweza beba VVU zinaweza zikabaki. Hivyo zinapomwagwa kwa mwanamke, kuna risk ya kumuambukiza. Hili halipo kwenye IVF, kwani yenyewe inachagua sperm cell yenye afya, na kuiunganisha na yai la kike lenye afya..then linapandikizwa.

Sperm washing to prevent HIV transmission from HIV-infected men but allowing conception in sero-discordant couples.

[h=3]Abstract[/h][h=4]BACKGROUND:[/h]Sperm washing is a term used to describe the process in which individual spermatozoa are separated from the seminal fluid. Sperm washing is used to prevent HIV transmission but allow conception in sero-discordant couples, where the male is HIV positive, but the female is HIV negative. This procedure is based on the observation that HIV cannot attach itself to spermatozoa, but it can be found in the fluid and cells surrounding spermatozoa.
[h=4]OBJECTIVES:[/h]To determine the benefits and harms of sperm washing of HIV-infected males when used to prevent the transmission of HIV but allowing conception in the HIV-negative female.
[h=4]SEARCH STRATEGY:[/h]We searched the Cochrane HIV/AIDS Group Controlled Trials Register, the Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, SCORPUS, AIDsearch, AJOL, LILACS and INDEX MEDICUS. We also searched the following conference proceedings for relevant abstracts:The International AIDS Conference; The Conference on Retroviruses and Opportunistic Infections (CROI); The British HIV Association (BHIVA) Conference; The International Conference of Obstetricians and Gynecologists (FIGO); The American Academy of HIV Medicine Conference; The Australasian HIV/AIDS Conference; The American Society for Reproductive Medicine (ASRM) conferences and website; The European Society for Human Reproduction and Embryology (ESHRE) conferences and websites, and the British Fertility Society (BFS) conferences and website. We also conducted a search of the website:
Home - ClinicalTrials.gov. The date of the most recent Cochrane HIV/AIDS Group Controlled Trials Register search was on the 10th of November, 2010.
[h=4]SELECTION CRITERIA:[/h]We preferentially looked for randomised or quasi-randomised controlled trials on sperm washing, aimed at preventing HIV transmission from HIV infected men but allowing conception in sero-discordant couples, irrespective of publication status, year of publication, or language in the review.
[h=4]DATA COLLECTION AND ANALYSIS:[/h]No relevant trials were identified for inclusion in this review.
[h=4]MAIN RESULTS:[/h]Forty four studies were identified, but none of them were suitable for inclusion in this review.
[h=4]AUTHORS' CONCLUSIONS:[/h]Reports on the use of sperm washing to prevent HIV transmission from HIV infected men but allowing conception in sero-discordant couples is currently limited to observational studies. No randomised controlled trial has assessed the benefit or risk of sperm washing to prevent HIV transmission from HIV infected men but allow conception in sero-discordant couples. Thus,
this systematic review identifies the need for a multicentre randomised controlled trial assessing the benefits and possible risks of sperm washing in preventing HIV transmission from HIV infected men but allow conception in sero-discordant couples.
