Cryopreserved sperm among patients with Oligoasthenoteratozoospermia.
Eur J Obstet Gynecol Reprod Biol
December 2024
Objectives: This study investigates sperm utilization and disposal patterns in Oligoasthenoteratozoospermia (OAT) patients undergoing long-term sperm storage. OAT is a major contributor to male infertility. Cryopreservation is a common practice as a "fertility insurance" in case of further deterioration until azoospermia.

- The study aimed to understand factors affecting the long-term use and disposal of cryopreserved semen straws among cancer patients over nearly three decades.
- Out of 445 participants, 55 used thawed semen for fertility treatments, 65 disposed of their straws, while a majority of 325 did neither, with younger patients showing lower rates of usage and disposal.
- The findings suggest a need for policies on cryopreservation that consider efficiency, cost, and patient demographics, potentially requiring consent from patients before preservation to alleviate unnecessary burdens.
Cryopreserved testicular spermatozoa among patients with azoospermia.
J Assist Reprod Genet
August 2024
Purpose: To investigate cryopreserved testicular spermatozoa among patients with azoospermia.
Methods: In this retrospective study spanning from October 1993 to December 2021, we examined men diagnosed with azoospermia who underwent testicular spermatozoa cryopreservation. Data from medical records included utilization and disposal of sperm samples, age at initial cryopreservation.
Objective: To study the preference of sperm donors with identity disclosure (ID) versus anonymous donors (AD) and to understand if this selection affects clinical outcomes in an Israeli population.
Methods: This retrospective study included patients who chose imported sperm donation during 2017-2021. Of these, 526 used their own (autologous) oocytes and 43 patients used donated oocytes (DO).
Background: Sperm banks initially focused on providing sperm donation (SD) to heterosexual couples grappling with severe male infertility. Notable advancements in fertility treatments and sociological trends have broadened the scope of SD toward single women and same sex female couples.
Objectives: To evaluate SD recipient characteristics over the last three decades in Israel according to demographic parameters.
Background: The wide implementation of sperm freezing presents a growing burden on sperm banks.
Objectives: To evaluate sperm freezing and usage patterns over 30 years, according to demographic parameters of age at first cryopreservation and number of children, and indication for cryopreservation.
Material And Methods: This retrospective, population based, cohort study included all sperm cryopreservation cases performed at a tertiary referral center from October 1993 to December 2021, among patients aged 18 years and older.
What can we learn about posthumous sperm retrieval after extra long-term follow-up?
J Assist Reprod Genet
July 2022
Purpose: To describe spermatozoa extraction rate by testicular sperm extraction (TESE) for posthumous sperm retrieval (PMSR) and examine harvest time impact on sperm motility; to compare long-term sperm usage between married vs. single deceased men.
Methods: This retrospective study included all PMSR cases in Shamir Medical Center during 2003-2021.
