Disturbances of Sperm Maturation and Minipuberty: Is There a Connection?
Male reproductive function in the general population raises an increased attention due to reports indicating declining sperm counts, increased occurrence of testicular cancer, cryptorchidism, and hypospadias. It is also hypothesized that prolonged exposure of the developing male, during both fetal a...

pubmed-39715142014-04-15 Disturbances of Sperm Maturation and Minipuberty: Is There a Connection? Živković, D. Fratrić, I. Review Article Male reproductive function in the general population raises an increased attention due to reports indicating declining sperm counts, increased occurrence of testicular cancer, cryptorchidism, and hypospadias. It is also hypothesized that prolonged exposure of the developing male, during both fetal and postnatal life, to exogenous estrogens could reduce Sertoli cell number and thus reduce sperm output (and sperm counts) in adult life. Fact is that infertility, which is defined as the inability to conceive after 1 year of unprotected intercourse, has a global prevalence of 9%. A male contributory factor is involved in approximately half of these cases, but most of the causes of reduced semen quality and other disturbances of male reproductive function are unknown. In the most affected men (azoospermic men) 15–20% had a prior history of cryptorchidism. The association between the cryptorchidism and infertility is one of the most studied potential causes of infertility. There are numerous studies that accentuate the importance of minipuberty for future fertility. Is it possible that a normal minipuberty ensures normal fertility despite malpositioned testes? And to move away from cryptorchidism, could impaired minipuberty be responsible for fertility problems in men who were born with both testes in their scrotal sacs?
