Lithium inhibits human sperm motility in vitro.
Lithium is a widely prescribed drug used for the treatment of bipolar affective illness. Previous reports on its effects on sperm motility and male fertility are conflicting. The effect of lithium on human sperm motility was examined in vitro using the modified transmembrane migration method. This technique takes account of the dilution of lithium that occurs during the incubation. Lithium inhi...
متن کاملThe effect of a copper-releasing intrauterine device on sperm penetration in human cervical mucus in vitro.
Improvements in the acceptability and effectiveness of the IUD involve developments in design of its shape such as the Dalkon Shield (Davis, 1971), or the addition ofa copper-releasing wire to the inert plastic material of the device, which was first reported by Zipper, Medel & Prager (1968). The copper could act at any stage in the reproductive process. It could interfere with sperm transport,...
متن کاملEvidence favoring sperm selection over sperm competition in the interaction between human seminal plasma and sperm motility in vitro.
The effect on sperm motility of sperm-sperm and sperm-seminal plasma interactions was studied among homologous and heterologous sperm. There were no significant interactions between sperm in vitro, but it was found that seminal plasmas of different donors have different effects on sperm motility, and different sperm react differently to the same seminal plasma. Sperm showed higher motility in a...
متن کاملMacaque sperm coating protein DEFB126 facilitates sperm penetration of cervical mucus.
BACKGROUND Sperm coating protein beta-defensin 126 (DEFB126) is adsorbed onto the entire surface of macaque sperm in the caudal epididymis and is retained on viable sperm collected from the cervix and the uterine lumen of mated female macaques. We investigated the role of sperm coating protein DEFB126 in cervical mucus penetration (CMP). METHODS Cervical mucus (CM) was collected from peri-ovu...
متن کاملThe In Vitro Impact of the Herbicide Roundup on Human Sperm Motility and Sperm Mitochondria
Toxicants, such as herbicides, have been hypothesized to affect sperm parameters. The most common method of exposure to herbicides is through spraying or diet. The aim of the present study was to investigate the effect of direct exposure of sperm to 1 mg/L of the herbicide Roundup on sperm motility and mitochondrial integrity. Sperm samples from 66 healthy men who were seeking semen analysis we...
