The plastic envelope method, a simplified technique for culture diagnosis of trichomoniasis.

Although culture of Trichomonas vaginalis is more sensitive than wet mounts in the diagnosis of trichomoniasis, the lack of convenience of culture prevents it from being widely used. To improve the acceptability of diagnosis by culture, a plastic envelope method (PEM) was devised. PEM permits both immediate examination and culture in one self-contained system.

Postcoital recovery of sperm in Douglas pouch aspirates of infertile patients.

Tubal dysfunction is certainly involved in some cases of infertility. Clinical diagnostic procedures for tubal patency are occasionally misleading and contradictory. Moreover, they provide no information on tubal function.

Effects of non-medicated and copper IUDs on sperm migration.

35 women of proven fertility who were scheduled for surgical sterilization by salpingectomy were selected for this study; 15 control patients, 10 patients using the Multiload (ML) Cu 250 IUD, and 10 fitted with nonmedicated IUDs. Increased copper concentration did not affect sperm receptivity by the cervical mucus, but did significantly affect sperm motility and survival. Nonmedicated IUDs did not interfere with sperm transport in the oviduct.
