What is the rate of embryo implantation?
The percentage of successfully implanted embryos out of the total number of embryos transplanted over a given period is known as the implantation rate. A developing embryo meets the uterine wall during the pregnancy stage known as implantation and is kept connected to it to receive oxygen and nutrients as it develops until birth. Less than half of IVF-related embryo transfer operations end in a clinical pregnancy, according to estimates.

Why Do IVFs Fail?
An infertile couple's chance of getting pregnant is helped through in vitro fertilisation and embryo transfer. However, clinical pregnancies only occur in roughly 30% of IVF transfer cycles. Poor quality embryos that are transferred during IVF may not successfully implant in the uterus. IVF failure can result from certain chromosomal defects and genetic variations in genes that prevent embryo implantation in the uterus.

Ovarian Stimulation Response Definition
In an IVF cycle, specific hormone-derived drugs are administered to encourage the ovaries to release multiple eggs. This raises the likelihood that the treatment will be successful and raises the possibility of becoming pregnant. Two important hormones, luteinizing hormone (LH) and follicle-stimulating hormone (FSH), are stimulated by the drugs. Individual responses to hormone injections used to induce ovulation vary and are challenging to predict. A poor or low response lowers the chance that IVF will be effective.

What is the Pregnancy Rate?
The success rate of an IVF patient becoming pregnant is known as the pregnancy rate. It is proof that a healthy foetus has been implanted. Age, the cause of infertility, prior pregnancies, the treatment regimen, the quantity of transferred embryos, etc. are some factors that affect the pregnancy rate.

Explanation of Recurrent Implantation Failure?
Recurrent implantation failure (RIF) is a clinical term that describes a scenario in which the embryo's implantation in the uterus-the first step in the development of a fertilised egg-has repeatedly failed, preventing the achievement of pregnancy. It refers to situations where women had three unsuccessful attempts at in vitro fertilisation (IVF) using high-quality embryos. 5% of women are predicted to experience two successive miscarriages, with an implantation failure accounting for over 75% of these cases.

Definition of Recurrent Pregnancy Loss
Recurrent pregnancy loss (RPL), a disease that affects 2-5% of couples, is indicated by two or more failed clinical pregnancies. Rearrangements in the chromosome structure, hormonal imbalances found in endocrine illnesses such insufficient progesterone secretion, excessive prolactin secretion, diabetes mellitus and polycystic ovarian syndrome are the main causes. The most frequent reason for sporadic miscarriages is foetal aneuploidy (chromosome presence or absence).
