- the example of the present invention comprises the separation of mobile cells of the spermatic type, however, the device and method are also applicable to other types of mobile cells, such as microorganisms or parasites.
- the present invention describes a device and a method of separating mobile cells, preferably sperm, which is not based on the budgets of a swim-up or those that use most other systems, but is based on two aspects 1 ) the search made by the gamete, or cell, of a space to enter, search that is random, aided by the shape of the channel and 2) the microcurrents that generate the same sperm and that end up guiding the following by reotaxis ( first induced by pressure difference and then self-induced by the passage through the narrow channel).
- the device of the present invention does not require any other laboratory element to achieve its purpose, that is, no additional tubes, or centrifuge or stove. Nor does it require electricity, which makes it a basic and innovative tool when it comes to extending assisted fertility practices to everyone, enabling both Health professionals such as veterinarians to have a tool for themselves to be arranged even in the least provided places.
- the incubation required by the method of the present invention can be performed by keeping the device locked in an adult's fist or in contact with the human body.
- the device of the present invention comprises a first reservoir (201), where the semen sample is placed from which it is desired to separate the sperm, a second reservoir (202) to which the sperm or mobile cells linked to both reservoirs are migrated and collected. using a screened plate (203).
- Said screened plate comprises one or more perforations that form channels through which the mobile cells migrate.
- Said perforations, called channels may have the same or different diameters according to the section of said channel that is measured, that is, taking into account the section that links to the first reservoir, the section that links to the second reservoir and the section which is between the aforementioned (both called external sections), now called in more intermediate section.
- the channels presented by the screened plate have equal diameters in all sections of said channels.
- the diameter of the channels is different in the sections that are linked to the reservoirs with respect to the intermediate section.
- said external sections of said channels have a diameter greater than the diameter of the intermediate section of said channel.
- said external sections of said channels have conical, hyperbolic or parabolic geometric shapes.
- the device of the present invention operates in the absence of filtering or the application of electromagnetism, or static currents or immunological labeling methods.
- the device of the present invention makes the sperm swim in the same way as it would in vivo, migrating together from a reservoir through a screened plate to another reservoir leaving behind detritus, sperm with mostly damaged DNA and cells not mobile
- the property of reotaxis, the design and natural behavior of the gamete is essentially used to penetrate interfaces (this behavior is observed to a greater extent in sperm with undamaged DNA).
- the device uses the sperm reotaxis property generated by a pressure difference between the two reservoirs, this being achieved as a result of a higher initial level of the second reservoir (where mobile sperm are recovered) that will be maintained until such time as balance the two pressures, although they also get involved as forces drivers of such current the capillarity and possibly the difference in concentrations in both reservoirs. Beyond the phenomenon that causes the current is a fact that there is a fluid flow from the second reservoir to the first, which generates the impulse for healthy sperm to swim against the current.
- This condition of the sperm most apt to pass or pass through the screened plate of the present invention is consistent, in the results, with the significant increase in the percentage of normal morphology and the highly significant decrease in the percentage of sperm with damaged DNA.
- the characteristics of the present invention allow a self-selection in gametes with rapid linear translational characteristics, which, as expected, coincide with a percentage in an increased normal morphology and with a higher percentage of conserved DNA (without alterations).
- the sperm are following a microcurrent produced by the flow between the recovery medium compartment and the semen compartment and then self-sustained by those who follow.
- the others are favored by the microcurrents produced by the first scourge to which the microcurrents of the successive scourges are added, thereby enhancing the current and therefore the effect of reotaxis.
- the sperm leave the seminal plasma on their own to access the insemination culture medium, leaving behind all seminal non-sperm elements in the seminal plasma (cells, detritus, immobile sperm and also sperm without reotaxis) since they do not have this ability of sperm to penetrate this type of holes.
- the device of the present invention comprises at least one plate screened with one or more channels of selected shapes among conical, hyperbolic, paraboloid of revolution, among many others that allow a widening in at least one of the ends of the channel as can be seen in figure 5.

- said first external diameter comprises between 50 and 200 ⁇
- said internal diameter comprises between 8 and 15 ⁇
- said second external diameter comprises between 10 and 50 ⁇ .
- the perforations of the screened plate comprise different geometric shapes such as cylindrical, conical, parabolic, hyperbolic, hyperbolic of revolution.

- the reservoirs of the device of the present invention comprise a volumetric capacity that depends on several factors: the amount of sample to be processed, the dimensions of the screened plate, among others.
- the reservoirs used for a 1x3 cm screened plate vary between 0.5 and 4.0 ml. It is essential to emphasize that the device of the present invention generates a current in the culture fluid or medium in such a way that the mobile cells, preferably the sperm cells, use their ability to swim against the current for their separation; said current is generated by a pressure difference in the reservoirs.
- the second reservoir contains a higher level, that way a current is generated to the first reservoir through the screened plate.
- the sample to be separated is loaded, and said second reservoir is loaded with a culture medium or fluid to recover the mobile cells separated from the rest of the population by their passage through said screened plate
- the device of the present invention separates the mobile sperm in a time between 1 and 90 minutes. Preferably, between 10 and 90 minutes.
- the device is adapted for the technique of intracytoplasmic sperm injection (ICSI).
- ICSI intracytoplasmic sperm injection
- the insemination with micro injection of semen to an oocyte can be useful to perform the separation of high performance sperm in the same injection plate.

Both reservoirs are covered by a coverslip (401) thus enabling a 10 ⁇ channel.
- the screen contains only one channel.
- FIG. 6 shows a cylindrical shape as shown in Figure 6, which comprises a cover (601), a hole near the opening of said tube (602), a first reservoir ( 604) and a second reservoir (603) where it can be observed that the enrase of the second reservoir, exit reservoir and collection of the selected sperm, is greater than the enrase of the first reservoir where the semen sample goes with the sperm to be separated.
- Figure 6 shows an enlargement of the section where the screened plate (605) is shown with the channels (606) through which the sperm flow.
- the mobile cell separation device of the present invention (MXM) consists of two reservoirs separated by a screened glass plate 130 ⁇ 40 ⁇ thick, with conical shaped channels of the length of the width of the glass, i.e. 130 ⁇ 40 ⁇ , a first diameter (inlet) of 15 ⁇ and a second diameter (outlet) of 8 ⁇ .
- MXM mobile cell separation device of the present invention
- the plate is 1 cm x 2cm, with a density of 6600 perforations / cm 2 .
- the first reservoir where the sample to be processed is placed, has a maximum volumetric capacity of 3ml_, and the second reservoir comprises a maximum capacity of 1 ml_.
- the PET-screened plate was made with 2500 channels, each 200 ⁇ long.
- the conical shaped channels comprise a first diameter (inlet) of 15 ⁇ and a second diameter (outlet) of 10 ⁇ .
- the size of the PET plate is 1 cm x 2 cm.
- the reservoirs are the same ones used for the glass sieve plate of Example 1. First, Ham F10 1X recovery medium with HEPES, supplemented with SSS and Penicillin / streptomycin was placed in the recovery reservoir (second reservoir); Semen sample A, B, C and D previously processed according to WHO2010 protocol was placed in the remaining reservoir (first reservoir).
- Step 1- The Ham F10 1X medium with HEPES (0.6-0.7 milliters) is placed until the second reservoir is rooted.
- the HamF10 1X is loaded with HEPES with a Pasteur pipette with a capillary tip (to enter the cuvette); When it is filled, it allows filling the screens with the HTF medium that will bathe the entire interior and the immediate surface of the semen side.
- Step 2 - Immediately afterwards, the semen sample is placed in the first reservoir. Be sure to completely cover the screened plate with the sample to be processed and make the most of the screened surface
- Step 3 The incubation of one hour (which can be between 1 minutes and 90 minutes) is carried out in contact with the body, although it can be done in an oven.
- Step 4 The device is removed from the incubation state (either from a stove or in contact with the body), a stove was used for example 2, at 36 ° C and the fist for example 1.
- the processed sample is taken of the recovery medium (that is, of the second reservoir) with syringe and tuberculin needle. This processed sample is ready to be used in artificial insemination.
- the% of sperm was tripled with normal forms compared to the direct one, going from 10.3% to 36.0% (for samples A, B, C, D), average values of the results obtained in each essay While in the case of swim-up only the value of sperm with normal forms almost doubles, going from 1 1.3% of normal forms to 18.0% with the method of the present invention.
- the swim-up technique is the normal basic technique for sperm recovery with a view to artificial insemination, of high or low complexity, with the disadvantage that given the exposure and handling time together with centrifugation that can lead to DNA alterations
- A, B, C, D passes from 13.3% pass from
- A, B, C, D passes
