Re: Diagnosis and management of recurrent urinary tract infections in non-pregnant women

Recurrent urinary infections and progesterone contraception

Gupta and Traunter write that recurrent urinary tract infection is common in otherwise healthy women.

They mention an increased risk due to sexual intercourse and use of spermicides but omit the increased risk of infection due progesterone based hormonal contraception which is immunosuppressive.1,2

It has long been known that urinary infections are more common in pregnancy. The Royal College of General Practitioners’ large oral contraceptive study cohort found increases in pyelitis and cystitis, and also in a range of various viral, bacterial and fungal infections, in women using combined progestogen/oestrogen oral contraceptives.3

Recent studies confirm that progesterone based hormonal contraceptives are immunosuppressive with increases autoimmune diseases and a wide range of infections including HPV and HIV.4-6 Invasive breast cancers and cervical cancers are still increasing. 7-8
