• procedure
  • In some of these cases, after suitable assessment a sperm retrieval procedure may be offered. (newcastle-hospitals.org.uk)

  • Posthumous sperm retrieval (PSR) is a procedure in which spermatozoa are extracted from a man after he has been pronounced legally brain dead. (wikipedia.org)
  • While religious arguments have been brought against the process even under these circumstances, far more censure has arisen from a number of quarters with regards to invasive retrieval from fresh cadavers or patients either on life support or in a persistent vegetative state, particularly when the procedure is carried out without explicit consent from the donor. (wikipedia.org)
  • While extraction of the sperm was guaranteed following a request by the partner, permission to use the sperm was to be determined case by case, a court of law deciding on the basis of the effect on the presumed wishes of the donor, and the effect of the procedure on the donor's dignity. (wikipedia.org)
  • Currently, as there are no national regulations or restrictions related to postmortem sperm retrieval, it is recommended that regulations are implemented at the local or institutional level prior to the need arising for discussions with patients or families around this medical procedure. (weillcornell.org)
  • Because multiple eggs are needed to have a good chance for success, the woman must go through ovarian stimulation and then an egg retrieval procedure. (santatifertility.com)
  • During the procedure, the male vas deferens are cut and tied or sealed so as to prevent sperm from entering into the urethra and thereby prevent fertilization. (wikipedia.org)
  • The procedure is regarded as permanent because vasectomy reversal is costly and often does not restore the male's sperm count or sperm motility to prevasectomy levels. (wikipedia.org)
  • Early failure rates, i.e. pregnancy within a few months after vasectomy, typically result from unprotected sexual intercourse too soon after the procedure while some sperm continue to pass through the vasa deferentia. (wikipedia.org)

  • donor
  • Some couples prefer to avoid this difficulty by choosing donor sperm to be available as a back-up. (newcastle-hospitals.org.uk)
  • The use of donor sperm as a back-up must be arranged well in advance of treatment. (newcastle-hospitals.org.uk)
  • Cases of post-mortem conception have occurred ever since human artificial insemination techniques were first developed, with sperm donated to a sperm bank being used following the death of the donor. (wikipedia.org)
  • His team were responsible for a number of innovations including the world's first IVF pregnancy 1973, world's first IVF baby developed using a frozen embryo 1983, world's first donor egg baby 1983, world's first IVF baby using sperm retrieval surgery 1986 and world's first Microinjection Intra Fallopian Transfer (MIFT) IVF baby 1992. (wikipedia.org)
  • When a woman is inseminated with her deceased husband's sperm, laws that establish that a sperm donor is not the legal father of the child born as a result of artificial insemination have had the effect of excluding the deceased husband from fatherhood and making the child legally fatherless. (wikipedia.org)
  • infertility
  • Infertility in some men may be due to an interruption in the sperm transport passages as a result of either a previous male sterilization operation (vasectomy), an anatomical birth abnormality (absence of the vas deferens), or a spinal/pelvic injury or operation. (conceivingconcepts.com)
  • To know whether sperm retrieval is the right male factor infertility treatment for you, you need to start by getting an accurate diagnosis to uncover the specific cause of infertility. (scrcivf.com)
  • Many couples with male factor infertility have successfully conceived with IVF using sperm extraction methods. (scrcivf.com)
  • CUA expands service in vasectomy reversal infertility sperm retrieva. (bio-medicine.org)
  • deferens
  • If sperm are found at the testicular end of the vas deferens, then it is assumed that a secondary epididymal obstruction has not occurred and a vas deferens-to-vas deferens reconnection (vasovasostomy) is planned. (wikipedia.org)
  • This is necessary when there is no sperm present in the vas deferens. (wikipedia.org)
  • enough sperm
  • Usually enough sperm is aspirated so that it can be split up into several vials and multiple attempts of IVF can be performed if that will be necessary. (conceivingconcepts.com)
  • If enough sperm is retrieved, it may be possible to freeze small amounts for use at a later stage. (newlifeclinic.org.uk)
  • Unfortunately, there is not enough sperm obtained to get any reasonable success rate from Intrauterine Insemination (IUI) of the female partner. (santatifertility.com)
  • man's
  • In these cases sperm may need to be surgically collected from inside a man's genitals instead of waiting for the sperm to be ejaculated out. (conceivingconcepts.com)
  • In the United Kingdom before 2000, birth records of children conceived using a dead man's sperm had to identify the infants as fatherless, but in 2000 the government announced that the law would be changed to allow the deceased father's name to be listed on the birth certificate. (wikipedia.org)
  • cryopreservation
  • At Weill Cornell Medicine, sperm retrieval is only considered when it can be done within 24 hours of death and cryopreservation resources are available to the family. (weillcornell.org)
  • To be able to retrieve and freeze/store the sperm within this 24-hour period requires cryopreservation resources that are both suitable and in close proximity, while also being available for immediate processing of the retrieved specimen. (weillcornell.org)
  • motile sperm
  • While medical literature recommends that extraction take place no later than 24 hours after death, motile sperm has been successfully obtained as late as 36 hours after death, generally regardless of the cause of death or method of extraction. (wikipedia.org)
  • Fewer men will eventually achieve motile sperm counts and the time to achieve motile sperm counts is longer. (wikipedia.org)
  • testis sperm
  • Assisted reproduction has undergone dramatic advances such that testis sperm are routinely used for biological pregnancies, thus fueling the development of novel FNA techniques to both locate and procure sperm. (wikipedia.org)
  • testes
  • By investigating the function of your testes we can give advice about the chances of retrieving sperm suitable for IVF treatment, upon which you can base your decisions. (newcastle-hospitals.org.uk)
  • testicles
  • At the base of the penis, sperm and testosterone (male hormone) are made in the scrotum's 2 testicles. (urologyhealth.org)
  • With this condition, the testicles make sperm but a block in the male's reproductive tract stops them from getting into semen. (urologyhealth.org)
  • Sperm are still produced by the testicles, but they are soon broken down and absorbed by the body. (wikipedia.org)
  • presence of sperm
  • Other, more subtle findings that can be observed in the fluid-including the presence of sperm fragments and clear, good quality fluid without any sperm-require surgical decision-making to successfully treat. (wikipedia.org)
  • conception
  • The first successful conception using sperm retrieved post-mortem was reported in 1998, leading to a successful birth the following year. (wikipedia.org)
  • Penile
  • The first-line method for sperm retrieval in men with spinal cord injury is penile vibratory stimulation (PVS). (wikipedia.org)
  • The penile vibratory stimulator is a plier-like device that is placed around the glans penis to stimulate it by vibration, and provides the first-line method for sperm retrieval in spinal cord injury patients with anejaculation. (wikipedia.org)
  • scrotum
  • The entry of the sperm into the scrotum can cause sperm granulomas to be formed by the body to contain and absorb the sperm which the body will treat as a foreign biological substance (much like a virus or bacterium). (wikipedia.org)
