A Prior History of Cryptozoospermia Is Associated with a Significantly Higher Chance of a Successful Microdissection Testicular Sperm Extraction Compared to Non-Obstructive Azoospermia.

Background: Our study sought to evaluate the rates of successful sperm retrieval following microdissection testicular sperm extraction (mTESE) in patients with a prior history of cryptozoospermia, compared to patients with non-obstructive azoospermia (NOA).

Methods: A retrospective chart analysis evaluating all mTESE procedures was performed from January 2004 to August 2018. Inclusion criteria involved all males >18 years of age with a diagnosis of cryptozoospermia and/or NOA that underwent a mTESE.

Acute anejaculation, hypogonadism, and fertility preservation in the setting of neurosarcoidosis: case report and literature review.

Objective: To examine fertility preservation techniques in the setting of neurosarcoidosis, and to review the impact of corticosteroid and methotrexate therapy on fertility.

Design: Case report of a patient with infertility secondary to anejaculation associated with spinal neurosarcoidosis, treated with systemic corticosteroids and methotrexate.

Setting: Academic tertiary-care hospital.

Online access to male factor infertility care: the challenge of finding a specialist.

Objective: To investigate internet search results available to couples searching for a male factor infertility specialist.

Design: Cross-sectional.

Setting: Online search engine.

Prevalence of Hyperprolactinemia and Clinically Apparent Prolactinomas in Men Undergoing Fertility Evaluation.

Objective: To determine prevalence of hyperprolactinemia and prolactinoma among men presenting for initial fertility evaluation.

Methods: We performed a retrospective review of men presenting for initial fertility evaluation at a tertiary care, academic health system between 1999 and 2018. Men with measured prolactin levels were analyzed to determine prevalence of hyperprolactinemia and prolactinoma.

Renal Papillary Mapping and Quantification of Randall's Plaque in Pediatric Calcium Oxalate Stone Formers.

Randall's plaque (RP) with attached stones is recognized as a primary mechanism for stone formation in adult calcium oxalate stone formers (CaOx SFs). The role of RP in pediatric stone pathogenesis is unknown, with no reported studies to date. The purpose of this study is to investigate renal papillary abnormalities and quantify RP in pediatric CaOx SFs.
