In-vivo transperitoneal fertilization (IVTPF) is a less invasive infertility treatment option. This technique offers advantages over other methods for male subfertility or unexplained infertility cases.

Area of Science:

  • Reproductive Medicine
  • Infertility Treatment
  • Surgical Techniques

Background:

  • Male subfertility and unexplained infertility are common causes of conception difficulties.
  • Existing assisted reproductive technologies (ART) vary in invasiveness and success rates.

Purpose of the Study:

  • To evaluate the efficacy and safety of in-vivo transperitoneal fertilization (IVTPF) as a first-line infertility treatment.
  • To compare IVTPF with other ART methods like GIFT, IVFET, and IUI.

Main Methods:

  • IVTPF involves transperitoneal transfer of processed spermatozoa into the pouch of Douglas post-ovulation induction.
  • A retrospective analysis of 136 treatment cycles in 89 couples over 4 years was conducted.

Main Results:

  • Eight pregnancies (9% per patient, 7% per cycle) were achieved.
  • Most pregnancies occurred within the first treatment cycle.
  • Sperm quality was superior in conceived patients, though pregnancy occurred even with severe oligozoospermia. One ectopic pregnancy was noted.

Conclusions:

  • IVTPF is a viable and less invasive initial approach for infertility due to male factors or unexplained causes.
  • The technique demonstrates reasonable success rates, particularly in the initial treatment cycles.
  • IVTPF offers advantages over IUI and is less invasive than GIFT or IVFET.
