PROISER. anonymity of donors

The Bioethics Committee asks the Government to end the anonymity of sperm and ova donors

The Assisted Reproduction Law only provides for reporting the identity of biological parents for medical reasons

 

The Spanish Bioethics Committee has asked the Government to change the law that regulates assisted reproduction treatments in Spain and to end the anonymity of ova and sperm donors. The proposal, embodied in a report that has been debated for months, aims to prioritize the “interests of children born by assisted reproductive techniques.” Although the petition is not retroactive, it would not affect children already born.

Spanish reproductive medicine not only meets the needs of the indigenous population but has also become the best international destination for fertility treatment. The quality of the treatments is one of the reasons why Spanish medical centres are chosen, but also the anonymity of donors. In several countries this has already disappeared and with it has brought a gigantic drop in the donation of gametes.

Until now, only the age and blood group of the donors were communicated to the recipients, but the bioethical organism considering another perspective that “it can only be up to the child of these techniques to decide whether or not he wants to know and to what extent”.

PROISER Fertility studies

Proiser develops fertility studies in freshwater fish

Proiser together with the University of Valencia develop fertility studies in sperm samples from humans and animals, and have obtained results in freshwater fish that could be useful to protect endangered species such as salt salmon.

Proiser is the name of a Valencian company whose work is carried out in the research and development of automated systems of diagnosis and automatic semen analysis.

Its origin is located in 2004, when Dr. Carles Soler (Professor of the University of Valencia in the field of Cell Biology, Functional Biology and Physical Anthropology), and computer engineer Francisco Blasco (Computer Engineer) join to develop semen analysis systems.

Proiser‘s main product line is the ISAS (Integrated Semen Analysis System) family, composed of CASA (Compuert Assisted Semen Analysis) systems, reusable and disposable cell counting chambers, and all the tools needed to perform numerous routine andrology lab analyses. Hence this company is at the forefront of what is going on in this field of biology and the environment.
The ISAS software used by Proiser is, today, the most advanced and cutting-edge solution to perform the automatic analysis of all types of semen. In fact, it is capable of analyzing more than 2000 cells per field, and more than 80,000 sperm by analysis. A job that will allow you to evaluate sperm mobility, sperm concentration, sperm morphology and other similar characteristics at the same time.

Fertility studies. Proiser products.

Currently, Proiser has a wide range of products that allow the correct manipulation, study and analysis of semen of different animals (including humans).

In addition, it develops its own lines of research such as the one that focuses its attention on the fertility of freshwater fish.

In this context, professionals from Proiser and the University of Valencia have already published results around sperm quality studies in humans and animals; as well as the results that have been obtained in freshwater fish, made with their own technique.

Particularly relevant have been its conclusions as far as salt salmon are concerned, a very important species at a commercial level and which has come to conclude, for example, that genetic-environmental interactions can be an important factor in the reproductive competition of male individuals of this species.
To carry out this work, Proiser has used a technique of his own with which they have been able to study sperm kinetics, thus identifying the different sub-populations of sperm that exist.
This work is part of Horizon 2020’s IMPRESS-Marie Sklodowska-Curie Program. A European programme that has allowed, for example, the experimental part to have been developed at the National Conservatory of Salmon Salar in the French town of Chanteuges.
PROISER ISAS Fertility Studies

 

This line of research highlights the important contribution of the Integrated Semen Analysis System (ISAS) in the study of different parameters of semen samples such as concentration, motility, percentage of progressives or different kinetic parameters and their use for scientific advancement in areas such as clinics, humans and veterinarians, scientific research, toxicology or livestock production among others.

ISAS V1

Multispecies sperm analysis: ISAS V1

ISAS V1 for Sperm tests, which are increasingly widespread evidence among the animal and human population. Hence, there is an increasing supply of systems on the market and, by extension, it is increasingly necessary to have systems that offer greater efficiency in the results obtained.
In Proiser we are aware of this, that is why we have developed the ISAS V1 method, a system that gathers tools to be used both in clinics and in research.

Its fields of application are both the field of human sciences and those related to veterinary, scientific research, livestock production or pharmaceutical and reproductive toxicology.

ISAS V1 is currently considered to be the most complete and easy-to-use sperm analysis system of all we can find on the market. This is mainly because it works under different hardware conditions and with different operating systems, so it adapts to the needs of all types of users.

ISAS V1: What it is and what applications it has

ISAS V1 is a sperm analysis system suitable for multiple species, so it can work with different sperm samples. It doesn’t matter if it is to analyze the sperm sample of a man, a horse, a bull, a pig, a goat, rabbit, dog, rat, lamb, etc. It’s valid for all of them. This does not imply that ISAS V1 always applies the same parameters. On the contrary, each species has its own configuration algorithms and results in independent analysis.

Depending on the sample, ISAS may use negative or positive phase contrast. The motility analysis of a field is performed in real time (less than one second), and can be configured to analyze motility up to 250 frames, at 200 frames per second and with concentrations greater than 1000 sperm/field.

In addition to the concentration, motility and percentage of progressives, with ISAS V1 the following kinetic parameters are also calculated: VCL, VSL, VAP, LIN, STR, WOD, ALH, BCF, DNC, MAD, among others.

It should also be noted that it works with cameras up to 200 frames per second, allowing for near-perfect analysis of sperm behavior.

In addition, it is specially designed for quality control programs, allowing the analysis of video files of many different formats (Windows AVI, Windows Media Video, MPEG-4, DV among others). It also allows to obtain images, which makes it easier to have collections of videos and images for offline analysis of mobility, concentration, morphology, vitality or DNA fragmentation.

Another application of ISAS V1 is the morphological and morphometric analysis of sperm from dyed or fresh samples (using phase contrast optics).
This work provides data on 14 morphometric parameters: head size (area, length, width and perimeter), head shape (ellipticality, elongation, roughness, and regularity), percentage of acrosome, head color level, centerpiece size (area and width), and insertion of the middle part (angle and distance).

With ISAS we can also know the data related to the percentage of fragmented sperm. To do this, it uses 20x or 40x real-time (less than 1 second) targets.

Finally, it should be noted that ISAS V1 also provides data on automatic feasibility of sperm cells. This is especially interesting because we need to determine the actual percentage of viable cells in a sample, and to accurately perform this analysis, we use fluorescence techniques with their corresponding use of tying kits.

FEATURES of the ISAS V1 system

The current ISAS V1 equipment is completely modular, so each part of it can operate independently and together.
In addition, we have designed the system to allow most of the components that can be found in each type of laboratory, from the microscope to the computer, as long as they meet the minimum system requirements.

So, if you are looking for a system with which you can do high quality multispecies sperm analysis and be able to obtain a large number of data, do not hesitate and come to Proiser. You’ll find everything you need.

One of them is the Isaspsus method, with the analysis of the semen of pigs is not only a simple act but allows to obtain a lot of data about their quality and possibilities of reproduction.

isaspsus

CASA SYSTEM ( Sperm Analyzers),  Isaspsus Method for swine semen

 Isaspsus Method

 Isaspsus  Method to analyze swine semen,  is a quiality meassuring system with which you want to know its composition and calibrate its quality before being used in the insemination processes of females. 

This system is based on a new concept with which sperm selection is carried out. A methodology based on simultaneous analysis of mobility and cell-by-cell morphology. And all of this analyzing thousands of sperm per second.

The parameters that allow to identify and know the Isaspsus method are the following:

  • The total number of sperm (per milliliter and per ejaculate).
  • The progressive movement of all of them (per milliliter and by ejaculate).
  • The morphology of the sperm tail (per milliliter and by ejaculate).
  • Total useful sperm (per milliliter, by ejaculate and per dose).
  • Tail abnormalities.
  • Cytoplasmic drops.

 

 

This method allows seminal dose production to be significantly increased by up to 40%. However, it is not the only advantage as it presents many others such as the following:

  • Calculate precise doses that we need in each case.
  • Develop real-time, non-dying morphometry detection.
  • Be able to recognize cytoplasmic drops.
  • Develop tail analysis
  • Definition of the useful sperm in each sample.
  • We can save images and results to the database we handle.
  • We can repeat the function every day, every month, or annually; and even do it on samples of the same animal
  • We can get reports in Excel to visualize the data more clearly.

spermtrack counting chamber

Combined effects of type and depth of counting chamber, and rate of image frame capture, on bull sperm motility and kinematics. Semen quality assessment requires accurate, reliable and objective methods.

Semen quality assessment requires accurate, reliable and objective methods for examination of sperm variables including sperm motility. For preparation of semen samples for artificial insemination, as a genetic resource, samples that are used for insemination need to have the capacity to result in a highly acceptable fertility rate. Several methods have been developed for evaluation of bull sperm in laboratory conditions and for preparation of doses for artificial insemination.

                       

spermtrack counting chamber

Spermtrack®

Computer-assisted semen analyses can provide objective information on various sperm variables. Nevertheless, this equipment requires fine-calibrations considering differences among species, breeds and conditions for sample evaluation and data analyses. In the present study, there was examination of the interaction between factors such as image frame rate and type and depth of counting chamber in which sperm were evaluated, together with differences between bulls of four breeds. The use of the Spermtrack® reusable 10 μm-depth  counting chamber provided more reliable results than results obtained using disposable counting chamber (10 and 20 μm depth). A capture rate of at least 90 fps is required for assessment of sperm motility percentage, whereas a rate of 250 fps is needed for obtaining consistent kinematic data. Differences among breeds in the present study indicate conditions for sperm analyses should include specific equipment calibrations for each breed. These results contribute to development of more precise conditions for assessments of bull sperm quality taking into account breed differences and the requirement each breed has for the adequate evaluation and preparation of samples for artificial insemination.

Influence of the microbiota of the reproductive tracts of females and males of the sheep species on their fertility

Using the technique of massive sequencing, interesting results over the influence of the microbiota of the reproductive tracts of females and males of the sheep species on their fertility.

Artificial insemination (AI) is an essential tool in genetic improvement programs, especially in dairy ruminants. In sheep, AI fertility has low percentages ranging between 30% and 60%, there are many factors that contribute to this fact.

The majority of fertility-related characters show very low heritability, between 1 and 4% (Andersen-Ranberg et al. 20015; Chang et al. 2006; González-Recio et al. 2006), which, together with The difficulty and time required for the collection of phenotypes, and the complexity and impression of the statistical models for their evaluation, make the selection of these characters using traditional methods inefficient.

Traditionally, the complete microbiota of the tract is not cultivable, so it has been tried to find out by other methodologies.

The INIA Animal genetic improvement group have found good conclusions about the influence of the microbiota of the reproductive tracts of females and males of the sheep species on their fertility , but there is still much to work on to clarify these issues and improve sheep production as in other species.
