Recovery of male DNA acquired from carrion‐feeding insects in a simulated sexual assault scenario

open access: yesJournal of Forensic Sciences, EarlyView.
Abstract When bodies of sexual assault victims are discovered in advanced stages of decomposition, the recovery of direct DNA evidence is often compromised, posing a challenge in criminal investigations. This study aimed to determine insect colonization and succession patterns on pig carcasses inoculated with semen and to assess the feasibility of ...

Reproductive outcomes, including neonatal data, following sperm injection in men with obstructive and nonobstructive azoospermia: case series and systematic review

open access: yesClinics, 2013
We compared pregnancy outcomes following intracytoplasmic sperm injection for the treatment of male infertility according to the type of azoospermia. First, we analyzed our data from 370 couples who underwent intracytoplasmic sperm injection using sperm ...

Azoospermia: a Genomic Review [PDF]

open access: yes, 2017
Azoospermia or the absence of sperm in semen is one of the sperm disorders that results in male infertility. There are two types of azoospermia, the first one isazoospermia caused by obstruction of the vas deferens (obstructive azoospermia) and the ...

Testicular histopathology and its association with germ cell numbers, serum concentrations of reproductive hormones, and semen quality

open access: yesAndrology, EarlyView.
Abstract Background It is well‐established that spermatogenesis, semen quality, and reproductive hormones are interlinked. It is, however, less well‐described how various specific testicular histopathologies are linked to reproductive hormones and semen quality.

Letrozole and Crocin: Protecting Leydig Cells and Modulating Androgen Receptor and CYP19 Gene Expression in Busulfan-Induced Azoospermia

open access: yesAnimals
This study aimed to investigate the impact of letrozole and crocin on Leydig cells on busulfan-induced azoospermia using a rat model. A sample population consisting of thirty male rats was randomly assigned to five groups: (1) the control group, (2 ...

The use of deidentified organ donor testes for research

open access: yesAndrology, EarlyView.
Abstract Our knowledge of testis development and function mainly comes from research using mammalian model organisms, primarily the mouse. However, there are integral differences between men and other mammalian species regarding cellular composition and expression profiles during fetal and post‐natal testis development and in the mature testis ...

A new TEX11 mutation causes azoospermia and testicular meiotic arrest

open access: yesAsian Journal of Andrology, 2021
There are many unknown genetic factors that lead to infertility in nonobstructive azoospermia men. Here, we performed whole-exome sequencing in blood samples obtained from 40 azoospermia patients with meiotic arrest and found a novel c.151_154del (p ...

Semen quality in patients with testicular cancer is associated with age and with greatly elevated levels of beta human chorionic gonadotropin

open access: yesAndrology, EarlyView.
Abstract Background Poor semen quality is a well‐known feature in patients with testicular germ cell tumours (GCTs) at the time of diagnosis but the underlying biological reasons are incompletely understood. Objectives This study aimed to identify GCT‐specific clinical factors that are involved with poor semen quality in GCT patients.
