Many others have not yet been assessed in regards to their effect on sperm function. This issue may concern couples trying to conceive both naturally and via artificial reproductive technologies ART. The aim of this research was to analyse the effects that lubricants, commonly used in the setting of natural conception and ART, have on sperm function in an in vitro setting. This was done by assessing sperm motility, vitality and DNA fragmentation following treatment with commercial lubricants or control preparations. Ten samples were obtained for the study from patients attending a fertility clinic. Sperm motility, vitality and DNA fragmentation were assessed to determine the effects of the lubricants on sperm function and DNA integrity.
Effect of an isotonic lubricant on sperm collection and sperm quality.
Over-the-counter vaginal lubricants have been shown to negatively affect in vitro sperm motility. The objective of this study was to estimate the effect of vaginal lubricant use during procreative intercourse on natural fertility. Women aged 30—44 years with no history of infertility who had been trying to conceive for less than 3 months completed a baseline questionnaire on vaginal lubricant use. Subsequently, women kept a diary to record menstrual bleeding, intercourse, and vaginal lubricant use and conducted standardized pregnancy testing for up to 6 months. Diary data were used to determine the fertile window and delineate lubricant use during the fertile window. A proportional hazards model was used to estimate fecundability ratios with any lubricant use in the fertile window considered as a time-varying exposure.
The effects of vaginal lubricants on sperm function: an in vitro analysis
Refrain from any sexual activity including masturbation for at least 2 days and no more than 10 days. Longer or shorter periods of abstinence may result in a lower sperm count or decreased sperm motility. A private room is available for semen collection within close proximity of our laboratory and is recommended for collection. The semen specimen should be obtained by masturbation. Alternate methods may be discussed but are not recommended.
Some might call the collection process the best part. Your testicles are constantly producing sperm. During an ejaculation, the sperm stored in your epididymis are shot out and fresh sperm come in.
