Intra-horn Penile Intromission in the Alpaca Vicugna pacos and Consequences to Genital Morphology.

Integr Comp Biol 2021 May 10. Epub 2021 May 10.

North American Camelid Studies Program, Nunoa Project, Belchertown, MA 01007, USA.

Copulatory behavior and genital morphology interact to deliver sperm more effectively during mating, but the nature of this interaction has not been explored in depth in most vertebrates. Alpacas have unusually long copulations lasting 15-20 minutes, and a unique copulatory behavior, where the penis intromits all the way past the cervix, into the uterine horns. Here we describe the morphology of male and female genitalia and report unique morphological characteristics that may be associated with this unusual insemination mode. Read More

Disorders/Differences of Sex Development Presenting in the Newborn With 46,XY Karyotype.

Front Pediatr 2021 22;9:627281. Epub 2021 Apr 22.

Paediatric and Adolescent Endocrinology, Division of Pediatrics, Department of Clinical and Experimental Medicine, University of Pisa, Pisa, Italy.

Differences/disorders of sex development (DSD) are a heterogeneous group of congenital conditions, resulting in discordance between an individual's sex chromosomes, gonads, and/or anatomic sex. The management of a newborn with suspected 46,XY DSD remains challenging. Newborns with 46,XY DSD may present with several phenotypes ranging from babies with atypical genitalia or girls with inguinal herniae to boys with micropenis and cryptorchidism. Read More

The role of imaging in pelvic exenteration for gynecological cancers.

Br J Radiol 2021 May 7:20201460. Epub 2021 May 7.

Institute of Diagnostic and Interventional Radiology, University Hospital Zurich, Zurich, Switzerland.

Pelvic exenteration (PE) is one of the most challenging gynecologic oncologic surgeries and is an overriding term for different procedures that entail radical en bloc resection of the female reproductive organs and removal of additional adjacent affected pelvic organs (bladder, rectum, anus, etc.) with concomitant surgical reconstruction to restore bodily functions. Multimodality cross-sectional imaging with MRI, PET/CT, and CT plays an integral part in treatment decision-making, not only for the appropriate patient selection but also for surveillance after surgery.

[Modern ideas about bulbourethral glands].

Urologiia 2021 May(2):128-134

V.I. Vernadsky Crimean Federal University, Simferopol, Republic of Crimea, Russia.

Bulbourethral glands are the accessory glands of the male reproductive system, the leading function of which is associated with ejaculation and includes both the neutralization of the acidic urine residues and environment of the female vagina, and friction reduction during the sexual intercourse. These glands play the role of immune barrier for urogenital infections, and also synthesize important autocrine and paracrine factors for the male urogenital system development. Glands pathologies usually have a subclinical course, however they can also lead to the functional disorders of the human urogenital system. Read More

Biol Reprod 2021 Apr 28. Epub 2021 Apr 28.

Department of Biological Sciences, University of Memphis, Memphis, TN 38152, USA.

Sex determination requires the commitment of bipotential gonads to either a testis or ovarian fate. Gene deletion of the kinase Map3k4 results in gonadal sex reversal in XY mice, and transgenic re-expression of Map3k4 rescues the sex reversal phenotype. Map3k4 encodes a large, multi-functional protein possessing a kinase domain and several, additional protein-protein interaction domains. Read More
