Placement of a Malecot catheter to enable embryo transfer after radical trachelectomy.

OBJECTIVE: To describe the use of a Malecot catheter as a stent after radical trachelectomy (RT). DESIGN: Case report. SETTING: Assisted conception unit at a teaching hospital in the United Kingdom. PATIENT(S): A 36-year-old woman undergoing IVF after her cervix had been excised for cervical carcinoma. Previous attempts at embryo transfer (ET) had been very traumatic and required a transmyometrial transfer on one occasion. INTERVENTION(S): A Malecot catheter was inserted into the uterine cavity after a dilatation procedure had been performed and removed before ovarian stimulation. MAIN OUTCOME MEASURE(S): Ease of ET. RESULT(S): The subsequent ET was much more straightforward. CONCLUSION(S): This technique can facilitate ET after RT if the passage is found to be stenosed.

Retrograde ejaculation and male infertility.

Incompetence of the internal urethral sphincter causes semen to pass into the bladder. Infertility can be successfully treated by restoring normal ejaculation or by sperm retrieval techniques.

A potential new use for gonadotropin-releasing hormone antagonists.

OBJECTIVE: To describe a potential new use of gonadotropin-releasing hormone (GnRH) antagonists. DESIGN: Case report. SETTING: Assisted conception unit at a teaching hospital in the United Kingdom. PATIENT(S): A 37-year-old woman undergoing in vitro fertilization (IVF) who accidentally stopped using GnRH agonists after starting ovarian stimulation. INTERVENTION(S): A GnRH antagonist was used to avoid a luteinizing hormone (LH) surge and hence "rescue" the cycle. RESULT(S): Successful oocyte retrieval was carried out, two embryos transferred, and a viable twin pregnancy ensued. CONCLUSION(S): This may be a new indication for the use of GnRH antagonists.

Perforation with the GyneFix intrauterine implant: is there a common factor?

This report describes an asymptomatic perforation with the GyneFix intrauterine contraceptive implant. A review of all other reports of this complication has been performed. Analysis of these reports suggests prolonged amenorrhoea secondary to continuous progestogen use as a possible common predisposing factor.
