Low-dose lignocaine pertubation significantly increased pregnancy rates in women with endometriosis, potentially by reducing sperm phagocytosis or affecting endometriotic implants.

The paper investigates whether low-dose lignocaine “pertubation” during tubal testing can improve fertility in women with early-stage endometriosis without pelvic adhesions, in light of laboratory evidence that peritoneal fluid from such patients has more leukocytes and increased capacity to phagocytose sperm, which lignocaine can reduce. In a clinical study, an overall pregnancy rate of 30% was observed, contrasted with a cited natural pregnancy rate for women with endometriosis of less than 5%. The authors state that confirmation requires a larger study and further dose-ranging, and they discuss possible mechanisms including reduced sperm phagocytosis and/or regression of endometriotic implants (supported by reduced pain after treatments). This paper is centrally about endometriosis—evaluating lignocaine pertubation as a potential fertility-improving treatment in women with endometriosis and impaired fertility.

Abstract

The causal relationship between reduced fertility and early stage endometriosis without pelvic adhesions is unclear. Peritoneal fluid from patients with endometrial peritoneal implants contains more leukocytes with an increased capacity to phagocytose spermatozoa. Peritoneal fluid supplemented with lignocaine has a reduced sperm phagocytosis capacity. The present clinical study with low-dose lignocaine pertubation sought to evaluate any clinical effect on fertility. An overall pregnancy rate of 30% was noted in contrast to the natural pregnancy rate for women with endometriosis which is <5%. To confirm these findings a larger study and further dose-ranging are in progress. Up to now the most effective way of increasing fertility for women with endometriosis or unexplained infertility is in vitro fertilisation (IVF). The pertubation treatment with lignocaine is inexpensive and less invasive. Its mechanism is thought to be reduced phagocytosis of the spermatozoa. Another explanation could be a regressive effect directly on the endometriotic implants, taking into account the reduced menstrual pain and increased pregnancy rate after all treatments have been completed. The finding may provide a minimal invasive and more cost-effective alternative to current treatments.
