Brief Summary:
The primary objective of this study is to determine if the use of frozen surgical testicular sperm specimens for ICSI lead to different IVF outcomes when compared with the use of fresh surgical testicular sperm for ICSI.

Condition or disease Intervention/treatment Phase
Infertility Other: Slow Freezing and Thawing Not Applicable

Detailed Description:
The study seeks to isolate the effect of slow freezing and thawing of surgical sperm specimens on fertilization and embryo blastulation rates by utilizing a randomized controlled split cohort protocol including men with obstructive azoospermia undergoing surgical sperm retrieval and good-prognosis female patients.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 65 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Other
Official Title: Randomized Controlled Trial Comparing Fresh Vs Frozen Surgical Sperm in In Vitro Fertilization Cycles
Estimated Study Start Date : October 2018
Estimated Primary Completion Date : December 2019
Estimated Study Completion Date : February 2020

Arm Intervention/treatment
No Intervention: Fresh surgical testicular sperm
Fresh, surgically obtained testicular sperm
Experimental: Frozen surgical testicular sperm
Surgically obtained testicular sperm that will undergo slow freezing and thawing
Other: Slow Freezing and Thawing
half of the surgically obtained testicular sperm will be frozen for 30 minutes and subsequently thawed prior to performing ICSI

Primary Outcome Measures :
  1. Blastulation Rate [ Time Frame: 5-7 days post ICSI procedure ]
    total number of embryos reaching the blastulation stage of development

Secondary Outcome Measures :
  1. Fertilization Rate [ Time Frame: 1 day post ICSI ]
    number of 2PNs

  2. Time to Find Sperm in Fresh Specimen [ Time Frame: up to 6 hours post surgery ]
    total amount of time spent finding sperm in the fresh surgical testicular sperm sample

  3. Post-thaw recovery rate of frozen surgical sperm [ Time Frame: 30 minutes after freezing ]
    analysis of sperm parameters post freezing

  4. Aneuploidy Rate [ Time Frame: 2 weeks post trophectoderm biopsy ]
    number of chromosomally normal and abnormal embryos

  5. Implantation Rate [ Time Frame: approximately 4-6 weeks post embryo transfer ]
    presence of fetal heart beat at discharge to obstetric care
