The spermatozoon is selected at higher magnification; the aim of this is to improve the chance of pregnancy. The use of high magnification for morphological sperm selection prior to ICSI has been associated with higher pregnancy rates and lower miscarriage rate.
It is uncertain whether ICSI improves live birth rates or reduces the risk of miscarriage compared with ultra‐high magnification (IMSI) sperm selection. [30] A systematic meta-analysis of 24 estimates of DNA damage based on a variety of techniques concluded that sperm DNA damage negatively affects clinical pregnancy following ICSI. [31]

ICSI sperm injection into oocyte. Oocyte cryopreservation (commonly referred to as OC or egg freezing) is a form of assisted reproductive technology (ART) used to preserve human eggs . The technique is often used to delay pregnancy. When pregnancy is desired, the eggs can be thawed, fertilized, and transferred to the uterus as embryos. The ...

This compares the number of divorces in a given year to the number of marriages in that same year (the ratio of the crude divorce rate to the crude marriage rate). [1] For example, if there are 500 divorces and 1,000 marriages in a given year in a given area, the ratio would be one divorce for every two marriages, e.g. a ratio of 0.50 (50%).
The United Nations Population Division, part of the DESA - Department of Economic and Social Affairs, [20] ranking list is based on the forecast/prediction for the years 2015-2020 and 2020-2025. [21] [22] Only countries/territories with a population of 100,000 or more in 2019 are included. Rankings are based on the 2015–2020 and 2020-2025 ...
