Converting Men From Clomiphene Citrate to Natesto for Hypogonadism Improves Libido, Maintains Semen Parameters, and Reduces Estradiol.

Objective: To evaluate outcomes including libido, semen parameters, testosterone, estradiol (E2), follicle stimulating hormone (FSH), and luteinizing hormone when converting men with low libido on Clomiphene Citrate (CC) to Natesto.

Methods: A retrospective chart review was performed. Baseline hormones prior to treatment, and again on CC and Natesto, as well as semen parameters on CC and on Natesto were assessed.

The impact of ipsilateral testicular atrophy on semen quality and sperm DNA fragmentation response to varicocele repair.

Varicoceles adversely impact semen quality and sperm DNA fragmentation, which typically improve with surgical repair. Some men with varicoceles have ipsilateral testicular atrophy due to damage from the varicocele. This study assessed semen quality and the sperm DNA fragmentation index (DFI) response to varicocele repair in men with ipsilateral testicular atrophy (TA) versus men with no testicular atrophy (NTA).

A comprehensive assessment of predictors of fertility outcomes in men with non-obstructive azoospermia undergoing microdissection testicular sperm extraction.

Background: Microdissection testicular sperm extraction (microTESE) in men with non-obstructive azoospermia (NOA) is the procedure that results in the highest number of sperm cells retrieved for in vitro fertilization (IVF). This study presents a novel assessment of predictors of sperm retrieval as well as downstream embryology and pregnancy outcomes in cases of men with NOA undergoing microTESE.

Methods: A retrospective chart review of 72 men who underwent microTESE for predictors of fertility outcomes including sperm retrieved at microTESE, embryology progression to embryo transfer (ET), clinical pregnancy, live birth, and surplus sperm retrieved for additional IVF/intracytoplasmic injection cycles beyond one initial cycle.

Factors associated with subchorionic hematoma formation in pregnancies achieved via assisted reproductive technologies.

Purpose: To determine if certain clinical and/or embryologic factors are independently associated with the increased prevalence of subchorionic hematoma (SCH) among pregnancies achieved via in vitro fertilization (IVF) with fresh embryo transfer (ET).

Design: Retrospective chart review.

Methods: In this retrospective study, data were abstracted from 210 autologous oocyte IVF clinical pregnancies that resulted from fresh ET at a single fertility center from January 2012 through December 2016.

Sertoli cell only syndrome induced by a varicocele.

A case is reported which describes the severity of testicular histological damage that can be induced by a high-grade varicocele in a male with secondary infertility. A chart review of a patient's case was performed. A 34-year-old male with a three-and-a-half-year-old son who was conceived spontaneously with timed intercourse, with a grade three left varicocele, who's semen parameters progressed to non-obstructive azoospermia (NOA).
