Comparison of Cumulative Live Birth Rates Between Progestin and GnRH Analogues in Preimplantation Genetic Testing Cycles.

Center for Reproductive Medicine, Guangdong Women and Children Hospital, Guangzhou 511400, Guangdong Province, China.
Context: Progestins have recently been used as an alternative for gonadotropin-releasing hormone (GnRH) analogues to prevent premature luteinizing hormone surge due to the application of vitrification technology. However, the long-term efficacy and safety of a progestin-primed ovarian stimulation (PPOS) regimen, including oocyte competence, cumulative live birth rate (LBR), and offspring outcomes, remain to be investigated.
Objective: To compare cumulative LBR of preimplantation genetic testing (PGT) cycles between a PPOS regimen and GnRH analogues.
Aim: Within the in vitro fertilization (IVF) process, to evaluate the possibility of using the state of the meiotic spindle of oocytes as an indicator of maturity in order to optimize the timing of vitrification.
Patients And Methods: In the presented report, the cause of couple infertility was a combination of a 38-year-old female and 43-year-old male with azoospermia, which was an indication for oocyte vitrification. Oocyte polar bodies and optically birefringent meiotic spindles were visualized by polarized light microscopy and their states and relative positions were used as indicators of oocyte maturation, i.
Sperm vitrification in horses and donkeys.

Sperm vitrification is an alternative freezing method, which includes high cooling rates and non-permeable cryoprotectants agents. The first attempt in equids was using the spheres technique by directly dropping small volumes of the sperm into liquid nitrogen. Later, vitrification was developed using 0.

London Women's Clinic, London, UK.
In 2014 a 36-year-old healthy female-to-male transgender patient attended the London Women's Clinic to consider oocyte and embryo freezing before sex reassignment surgery. The patient began IVF treatment in 2015; from two cycles, nine metaphase II oocytes and five blastocysts were frozen. Three years later the patient returned with his partner, a 39-year-old healthy transgender male-to-female individual, ready to start a family with surrogacy treatment.
