The most common form of sterilization in dogs and cats is surgical, spaying in females and castration in males. Non-surgical fertility control can either result in sterilization or temporary contraception and could offer a cheaper way to keep wild dog and cat populations under control.

Autologous endometrial coculture is a possible treatment for patients who have failed previous IVF attempts or who have poor embryo quality. The patient's fertilized eggs are placed on top of a layer of cells from the patient's own uterine lining, creating a more natural environment for embryo development.
In terms of insemination, ICSI needs only one sperm cell per oocyte, while IVF needs 50,000–100,000. This is because the acrosome reaction has to take place and thousands of sperm cells have to be involved in IVF. Once fertilized, the egg is transformed into a pre-embryo and it has to be transferred to the uterus to continue its development.
The timeline of reciprocal IVF depends on if a couple chooses to undergo a fresh or a frozen transfer: A fresh embryo transfer IVF cycle lasts around 17–20 days and 10 days after the embryo is transferred to wait for the results of a pregnancy test. [14] A frozen embryo transfer first involves one of the cycles dedicated to the genetic mother.
Freezing embryos for IVF became standard practice after the development of vitrification, a fast-freezing process that is safer for the embryo. While there’s still a risk of damage during the ...
Following feature extraction, ERICA accurately ranks embryos according to their prognosis (defined as euploidy and implantation potential). In this way, ERICA removes the subjectivity inherent to previously existing classifications and, by efficiently assisting clinicians, increases the chances of selecting the one embryo with the best chances ...
It is used in instances where the fertility problem relates to sperm dysfunction, and where the couple has idiopathic (unknown cause) infertility. Some patients may prefer the procedure to IVF for ethical reasons, since the fertilization takes place inside the body. [4] This is a semi invasive procedure and requires laparoscopy.
