Sperm donation
A gesture of solidarity to help couples fulfil their dream of starting a family.
At Next Fertility ProCrea we have been helping couples with male donor treatments for over 20 years, applying a rigorous system of sperm donor selection, comprising all the recommendations of the main national and international scientific bodies.
We work with both our in-house bank and selected international biobanks, thus offering the best guarantees for treatment requiring donation. Our peace of mind stems from the knowledge that all donors undergo an exhaustive set of medical, genetic and psychological tests before being accepted into donation programs.
Donation itself is a completely altruistic and selfless gesture.

Selection of
sperm donors
To be able to offer the best results in treatments with donor sperm, it is essential to be able to depend on a sperm bank of the highest quality.
Our bank has one of the most demanding donor selection procedures, with constant testing for sexually transmitted and genetic diseases. In addition, all donors must meet sperm parameters above World Health Organization standards and recommendations.
What will your donor be like?
We will choose the donor who best matches the phenotypic characteristics of the male partner of the recipient couple: i.e., blood type, skin type, eye colour, hair colour and type, weight, height…
We will also be able to select the best donor at a genetic level by performing the genetic compatibility test between the patient and the donor.
Requirements for donating sperm
Sperm donors must be between 18 and 40 years old and meet specific medical and psychological requirements.
We carry out an exhaustive anamnesis, a reproductive history (if the donor has children, pregnancies or abortions in his relationships), profession, lifestyle… to get as much information as possible about the future donor.

Selection process
It is important to verify that the donor is in excellent health.
All of our donors undergo the following tests:
- Genetic: karyotype, CFTR (Cystic Fibrosis) gene mutations, SMA, CARRIER SCREENING (required for subsequent genetic compatibility testing with the applicant patient)
- Biochemcal:
thalassemia, favism (G6PdH), C-reactive protein, general clinical chemistry - Infectious diseases:
1. BY MEANS OF PCR (POLIMERASE CHAIN REACTION): HIV, HCV, HPV,CHLAMYDIA T., NEISSERIA G., UREAPLASMA U., MYCOPLASMA H., MYCOPLASMA G., TRICHOMONAS V.
2. BY MEANS OF SEROLOGY: CMV (IGG, IGM), HIV, TREPONEMA P. (VDRL), TREPONEMA (TPHA), HTLV, HEPATITIS-B AGHBS, HEPATITIS-B ABHBS, HEPATITIS-B ABHBC, HEPATITIS-A IGM, HEPATITIS-C AB
3. BY MEANS OF CULTURE TESTS – GARDNERELLA V., STREPTOCOCCHI, UREAPLASMA U., MYCOPLASMA H. AND GENERAL BACTERIOLOGY
Bacteriological checks on the seminal fluid are carried out regularly during the donation cycle, while the complete screening (biochemical and for infectious diseases) is repeated 180 days after the end of the donation cycle.
If all the above requirements are met, we move on to the second phase of the study, which is the analysis of the sperm sample. In addition to the usual parameters of sperm quality, we subject the sperm to bacteriological research to eliminate any pathogenic microorganism that may cause failures in the In Vitro Fertilization processes.
