Alternative approaches in IVF [PDF]

Human Reproduction Update, 2002
Various new developments in clinical and basic science which may impact on IVF in the near or distant future will be discussed in this review. These key areas include the regulation of early follicle development and the extended in-vitro culture of oocytes and embryos. Moreover, alternative compounds and ovarian stimulation protocols will be discussed,

Case of Inherited Partial AZFa Deletion without Impact on Male Fertility

Case Reports in Genetics, 2019
Male factor infertility accounts for 40–50% of all infertility cases. Deletions of one or more AZF region parts in chromosome Y are one of the most common genetic causes of male infertility. Usually full or partial AZF deletions, including genes involved

Successful pregnancy and live birth despite discontinuation of hormone replacement therapy at 3 weeks and 5 days of gestation following vitrified-warmed embryo transfer under a hormone replacement therapy cycle: a case report and literature review

BMC Pregnancy and Childbirth
Background In freeze–thawed embryo transfer (FET) cycles, hormone replacement treatment (HRT) is crucial for implantation and pregnancy maintenance. HRT typically continues until the 10th week of pregnancy owing to a luteoplacental shift, although a ...
