Alexey Lobkarev’s Sperm Viscosimetric Nomogram

In order to objectify the evaluation of ejaculate viscosity and make it accessible directly to married couples in home, intimate conditions, the author launched the production of a ceramic funnel with a volume of one milliliter, having an outlet channel diameter of 1.5 millimeters - "Alexey Lobkarev's Funnel". Objective: to develop Alexey Lobkarev's spermoviscosimetric nomogram based on statistical analysis of data obtained using Alexey Lobkarev's funnel, and to introduce the term "sperm viscosiflowmetry" and the methodology for its implementation into clinical practice. Materials and methods. The funnel is used by men according to the instructions: during the first minute after ejaculation, it is necessary to fill it with ejaculate, place it horizontally and note the time (in seconds) required for the funnel to empty. A statistical analysis of the time values was conducted. Results. The author suggests that the range from 657 seconds to 4041 seconds be considered the normal range of the Lobkarev’s parameter. Conclusions. The author developed Alexey Lobkarev's spermoviscosimetric nomogram. The term "sperm viscosiflowmetry" and the method for its implementation were also proposed.
