On September 23, the Verifica section of la diaria labeled our publication about the new guide from the Ministry of Public Health as false. The problem is that the summary of their own article confirms the essential point: the update of the Health and Sexual Diversity Guide states that puberty blockers can be considered when puberty begins, starting from stage 2 of the Tanner scale, and la diaria adds that the guide "does not set a minimum age." That does not disprove anything. It aggravates it.
What the guide says
The MSP presented the new edition of the guide on September 3, 2026, at the agency's headquarters. The document includes a chapter 8 on childhood and adolescence, the second part of which is titled "Use of medication for puberty suppression in childhood and adolescence." The 2025 edition was coordinated by Florencia Forrisi, who in June 2025 transitioned from the Colectivo Ovejas Negras to coordinate the Gender and Sexual Diversity Program of the MSP, and the preface is signed by Minister Cristina Lustemberg, who presents the challenge of advancing the implementation of these guidelines and ensuring their compliance throughout the national territory.
This is not a standalone academic paper: it is an official document with ministerial endorsement.
La diaria itself acknowledges that it considers the possibility of using gonadotropin-releasing hormone (GnRH) analogs to halt the progression of puberty once it has begun.
What age is "Tanner 2"?
Pediatrics is clear on this. The Latin American Society of Pediatric Endocrinology places the onset of breast development in girls around 10.9 years, with limits of 8 to 13. In boys, puberty begins at an average age of 11.5 to 12 years, within a range of 9 to 14. Without a minimum age, the guide's criteria applies to a girl who starts her puberty at 8 years old. Saying "starting at 10" was, if anything, conservative.
