Semen parameters in testicular tumor patients before orchiectomy: What is the impact of testicular tumor stage and histology?

Purpose: To evaluate the influence of testicular cancer histology and stage on sperm parameters in cryopreserved samples collected prior to orchiectomy.

Materials And Methods: We conducted a retrospective analysis of tumor histology, stage and sperm parameters of patients who underwent pre-orchiectomy sperm cryopreservation for testicular cancer between March 2010 and March 2023. The World Health Organization (WHO) 2010 sperm reference values were used to identify patients with subnormal semen parameters and to further categorize patients by sperm alteration.

Specialist management of testicular cancer: Report of the last 10 years at a Portuguese tertiary referral academic centre.

Objectives: To describe our experience on testicular cancer (TC) management, underlining the clinical/pathological scope, administered treatments, outcomes, and challenges. TC incidence is rising globally. The predominant histology is germ cell tumour (GCT).

[Consensus on HPV of the Portuguese Society of Andrology, Sexual Medicine and Reproduction: Treatment].

The treatment of condyloma is generally a challenge in clinical practice. Although the spontaneous resolution rate is high, a significant proportion of patients seek treatment, not because of symptomatology, but mainly for aesthetic issues and concerns related to the transmission or worsening of existing lesions. The available treatments should be applied only for clinically evident macroscopic lesions.

[Preservation of fertility in transgender people].

Young transgender people increasingly seek medical help to assist them in their gender transition with hormone therapy and/or sex reassignment surgery. However, these treatments limit fertility and may make them irreversibly infertile. Studies show that the transgender population wishes to have biological children and, to help them achieve this desire for parenthood, there are techniques for preserving fertility, such as cryopreservation of gametes, embryos and ovarian or testicular tissue.

L-cysteine/hydrogen sulfide pathway induces cGMP-dependent relaxation of corpus cavernosum and penile arteries from patients with erectile dysfunction and improves arterial vasodilation induced by PDE5 inhibition.

The aim was to evaluate and characterize HS-induced relaxation of human corpus cavernosum (HCC) and penile resistance arteries (HPRA) from patients with erectile dysfunction (ED). HCC and HPRA were obtained from men with ED at the time of penile prosthesis insertion. HS-mediated relaxations were evaluated by exposing these tissues to the stable analogue, NaHS, and to the precursor of HS, L-cysteine (CYS).
