Fallopian Tube Sperm Perfusion

Another Simple Non-Invasive Method




Studies on the dynamics of sperm transport have shown that there is a progressive decline in the number of sperm along the length of the female reproductive tract. In the ampulla of a patent tube, a maximum of only 200 sperm is present after intercourse. Ripps et al. (1994) showed that the number of sperm in the pouch of Douglas after IUI was very low. However, it has been shown that the number of motile sperm can be significantly increased with fallopian tube sperm flushes (Kahn et al., 1992).

Taking these observations into consideration, another simple non-invasive method was introduced called Fallopian tube sperm perfusion (FSP). This technique was developed to ensure the presence of higher sperm densities in the Fallopian tubes at the time of ovulation compared with standard IUI.

Fallopian tube sperm perfusion is based on pressure injection of 4 ml of sperm suspension with an attempt to seal the cervix to prevent semen reflux. This results in a sperm flushing of the Fallopian tubes and an overflowing of the inseminate into the pouch of Douglas (Kahn et al., 1992; Fanchin et al., 1995). With IUI, on the other hand, 0.3–0.5 ml of sperm suspension is inseminated.

Adopt Embryos

Why Choose Embryo Adoption

A more private way to adopt

The process of receiving donated embryos is less obvious to the public which allows for more privacy than traditional adoption.

  • Greater degree of privacy
  • Anonymous
  • More control of timing

More convenient than IVF

Some intended parents may choose embryo adoption for its speed and convenience

  • Fewer procedures than IVF
  • No surgical retrieval
  • Fewer medications

More cost-effective

Embryo adoption is a fraction of the cost of traditional adoption and less than the average cost of IVF

  • Lower cost than traditional adoption
  • Lower cost than most IVF options
  • Lower cost medications

Less waiting

The waiting period for embryo adoption can be shorter than that traditional adoption and often quicker than IVF

  • Shorter waiting times
  • Quicker than IVF
  • Fewer clinic visits

Genetic diversity

In some cases, intended parents may wish to have a child who doesn't share their genetic material for medical reasons or personal ones.

  • Avoid passing on a hereditary disease
  • Choice of genetic makeup
  • Increased potential for a healthy baby

High success rates

Compared to IVF with you own eggs and sperm, using donated embryos often has a similar or higher success rate

  • Typically better outcomes
