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.
Although many Fertility Centers have adopted day 5 or 6 embryo transfer policy, yet, 30% of embryo transfers in the US are performed on day 3. This is mainly due to concerns related to longer embryo culture effect and higher rates of embryo transfer cancellation on day 5, with no effect on cumulative pregnancy rate. We conducted a retrospective cohort study comparing individual embryo transfer order rank, best embryo for fresh transfer and intention to freeze, of day-3 and day-5 embryos based on their morphology score.

We conducted a prospective study of 146 GnRH antagonist oocyte pickup (OPU) cycles to evaluate GnRHa stimulation test (GAST). On day 2 of the cycle, basal E2 were measured, followed by injection of 0.

- Sperm banks have evolved to focus on single women and female couples instead of just heterosexual couples with male infertility, reflecting societal changes and advances in fertility treatments.
- A study analyzed the demographic trends of 4,265 single women who received sperm donations in Israel over a 30-year period, dividing the data into six 5-year periods.
- Findings showed that the average age of single women seeking sperm donation decreased from 39.58 years to 38.08 years, with Ashkenazic and Sephardic Jews being the predominant ethnic groups, while women from conservative backgrounds tend to seek sperm donation later in life.
