Mild coronavirus disease 2019: Results of a multicentric prospective study on severe acute respiratory syndrome coronavirus 2 presence in semen fractions and cells and its effects on semen parameters.

Background: Severe acute respiratory syndrome coronavirus 2, the virus responsible for coronavirus disease 2019, affects multiple organs. The virus enters cells through angiotensin-converting enzyme-2 and host factors present in genital organs, leading to concern over virus shedding in semen and reproductive function.

Objectives: To investigate severe acute respiratory syndrome coronavirus 2 in semen from patients with a mild infection, identify the seminal infected cells, and explore the effect of the infection on sex hormones and semen parameters.

[The sociological approach to vasectomized patient trajectories at the Buenos Aires University Clinical Hospital "José de San Martín"].

According to the Argentinian Ministry of Health records the number of patients requesting vasectomy increased twelve times in public hospitals in 2015-2019. The physicians and specialists account for this change in recent years, arguing, among other reasons, cultural change when male assumes active position in contraceptive methods. The article addresses vasectomized patient trajectory at the Buenos Aires University Clinical Hospital "José de San Martín".

Analytical quality specifications in semen analysis according to the state of the current methodologies.

Objectives: The aim of this study was to establish analytical quality specifications for human semen measurands according to the state of the current methodologies.

Methods: Measurement errors were estimated based on data from participating laboratories in the External Quality Program (PEEC) led by the Argentine Biochemistry Foundation using the "Analytical Quality Minimum Specifications" model established in Spain for other biochemical collection parameters. Semen samples from the PEEC were analyzed according to WHO procedures.

Classical congenital adrenal hyperplasia due to 21-hydroxylase deficiency (21-OHD) in adult males: Clinical presentation, hormone function and the detection of adrenal and testicular adrenal rest tumors (TARTs).

Introduction: 21-hydroxylase deficiency (21-OHD) is the most common form of congenital adrenal hyperplasia (CAH). In adulthood, most studies are reported in females. By contrast, data on adult males are scarce.

Is the Wnt/β catenin signalling pathway activated in Seminoma?: An immunohistochemical study.

Background: The loss of reduction of some adhesion molecules is associated with the invasive phenotype of carcinomas. The aim of this paper was to study the expression of some proteins related to the Wnt/β catenin signalling pathway in seminomas by immunohistochemical techniques in order to assess the contribution of this pathway to the tumoral development.

Materials And Methods: Immunohistochemistry for E-cadherin, β-catenin, vimentin, C-Myc, cyclin D1 (CD1) and placental alkaline phosphatase.

Thyroxin Is Useful to Improve Sperm Motility.

Background: The aim of this study was to evaluate the non-genomic action of thyroxin on sperm kinetic and its probable use to improve sperm recovery after applying an en- richment method like "swim-up" in comparison with the available one, pentoxifylline.

Materials And Methods: This is an experimental study. A total of 50 patients were re- cruited, followed by infertility consultation.

Computer-aided sperm analysis: a useful tool to evaluate patient's response to varicocelectomy.

Preoperative and postoperative sperm parameter values from infertile men with varicocele were analyzed by computer-aided sperm analysis (CASA) to assess if sperm characteristics improved after varicocelectomy. Semen samples of men with proven fertility (n = 38) and men with varicocele-related infertility (n = 61) were also analyzed. Conventional semen analysis was performed according to WHO (2010) criteria and a CASA system was employed to assess kinetic parameters and sperm concentration.

Nutrition and Reproductive Health: Sperm versus Erythrocyte Lipidomic Profile and ω-3 Intake.

Fatty acid analyses of sperm and erythrocyte cell membrane phospholipids in idiopathic infertile patients evidenced that erythrocyte contents of EPA, DHA, omega-6-omega-3 ratio and arachidonic acid provide a mathematical correspondence for the prediction of EPA level in sperm cells. The erythrocyte lipidomic profile of patients was significantly altered, with signatures of typical Western pattern dietary habits and no fish intake. A supplementation with nutritional levels of EPA and DHA and antioxidants was then performed for 3 months, with the follow-up of both erythrocyte and sperm cell membranes composition as well as conventional sperm parameters.

A rare case of respiratory disorders associated with two autosomal recessive diseases and male infertility.

The study of nasal ciliary beat frequency (CBF) and ultrastructure may contribute to the understanding of pathognomonic cases of male infertility associated with defects in sperm motility. This study was designed to report a particular case of male infertility, characterized by the association of two respiratory autosomal recessive genetic diseases (alpha-1-antitrypsin deficiency [AAT-D] and primary ciliary dyskinesia [PCD]). A 39-year-old patient with complete sperm immotility, AAT-D, and bronchiectasis was studied in the Laboratory of Male Fertility, the Department of Urology, the Respiratory Center of a Pediatric Hospital, and in the Department of Clinical Medicine of a Rehabilitation Respiratory Hospital.

In vivo antigenotoxic activity of watercress juice (Nasturtium officinale) against induced DNA damage.

The present study was carried out to investigate the genotoxicity as well as possible protective activity against damage induced by cyclophosphamide (CP) of the aqueous juice of watercress (Nasturtium officinale, W.T. Aiton) in vivo.
