Other assisted reproduction techniques include:
* [[Mitochondrial replacement therapy]] (MRT, sometimes called mitochondrial donation) is the replacement of [[mitochondria]] in one or more cells to prevent or ameliorate disease. MRT originated as a special form of IVF in which some or all of the future baby's [[mitochondrial DNA]] comes from a third party. This technique is used in cases when mothers carry genes for [[mitochondrial diseases]]. The therapy is approved for use in the United Kingdom.<ref>{{Cite journal |last=Scully |first=Jackie Leach |date=January 2017 |title=A Mitochondrial Story: Mitochondrial Replacement, Identity and Narrative |url=https://pubmed.ncbi.nlm.nih.gov/27973722/ |journal=Bioethics |volume=31 |issue=1 |pages=37–45 |doi=10.1111/bioe.12310 |issn=1467-8519 |pmid=27973722|hdl=1959.4/unsworks_66960 |hdl-access=free }}</ref><ref name=NAS2016ethics>{{cite book|editor1-last=Claiborne|editor1-first=Anne|editor2-last=English|editor2-first=Rebecca|editor3-last=Kahn|editor3-first=Jeffrey|title=Mitochondrial Replacement Techniques: Ethical, Social, and Policy Considerations|date=2016|publisher=National Academies Press|doi=10.17226/21871 |pmid=27054230 |isbn=978-0-309-38870-2|url=https://www.nap.edu/read/21871/chapter/1|last1=Claiborne |first1=A. |last2=English |first2=R. |last3=Kahn |first3=J. }} [http://nationalacademies.org/hmd/reports/2016/Mitochondrial-Replacement-Techniques Index page] {{Webarchive|url=https://web.archive.org/web/20181126135516/http://www.nationalacademies.org/hmd/reports/2016/Mitochondrial-Replacement-Techniques |date=2018-11-26 }} with links to summaries including [http://www.nationalacademies.org/hmd/~/media/Files/Report%20Files/2016/Mitochondrial%20Replacement%20Techniques/mito%20ethics%20infographic_FINAL.pdf one page summary flyer] {{Webarchive|url=https://web.archive.org/web/20171030233717/http://www.nationalacademies.org/hmd/~/media/Files/Report%20Files/2016/Mitochondrial%20Replacement%20Techniques/mito%20ethics%20infographic_FINAL.pdf |date=2017-10-30 }}.</ref><ref name=2015CreeRev>{{cite journal|last1=Cree|first1=L|last2=Loi|first2=P|title=Mitochondrial replacement: from basic research to assisted reproductive technology portfolio tool-technicalities and possible risks.|journal=Molecular Human Reproduction|date=January 2015|volume=21|issue=1|pages=3–10|pmid=25425606|doi=10.1093/molehr/gau082|doi-access=free}} {{open access}}</ref>
* In [[gamete intrafallopian transfer]] (GIFT), a mixture of sperm and eggs is placed directly into a woman's fallopian tubes using laparoscopy following a transvaginal ovum retrieval.
* [[Reproductive surgery]], treating e.g. [[fallopian tube obstruction]] and [[vas deferens obstruction]], or reversing a [[vasectomy]] by a [[reverse vasectomy]]. In [[surgical sperm retrieval]] (SSR), the reproductive urologist obtains sperm from the vas deferens, epididymis or directly from the testis in a short outpatient procedure.
* By [[cryopreservation]], eggs, sperm and reproductive tissue can be preserved for later IVF.
