The use of Intracytoplasmic sperm injection (ICSI) has increased in the last decades regardless of the cause of infertility. Despite the increased use there is no clear evidence that ICIS ...
A multicenter, parallel-controlled(1:1 treatment ratio), double-blinded, randomized clinical trials regarding fertilization and pregnancy outcomes between ICSI and conventional IVF among c...
Infertility has been estimated to affect from 6-18% of couples trying to conceive. In 20-30% of cases, the problem is with the male. Varicocele is a common cause of male factor infertility...
In this prospective randomized clinical trial we plan to compare two fertilization method which are widely used during in vitro fertilization (IVF) treatment. Outcome of conventional IVF a...
This will be a prospective, randomized (1:1 ratio) clinical trial for patients with male-factor infertility with or without preimplantation genetic screening (PGS). Qualified 650 patients ...
What is the cumulative live birth rate following ICSI cycles compared with IVF cycles for couples with non-male factor infertility?
Human sperm morphology has been described as an essential parameter for the diagnosis of male infertility and a prognostic indicator of natural or assisted pregnancies. Nevertheless, standard morpholo...
It has been forty years since the first IVF child, Louise Brown, born in 1978 and now more than 7 million children are conceived after assisted reproductive technologies (ART). There has been a tremen...
Intracytoplasmic sperm injection (ICSI) is well established and provides patients with severely impaired sperm quality with an opportunity to father a child. However, previous studies do not clearly i...
Inability to reproduce after a specified period of unprotected intercourse. Reproductive sterility is permanent infertility.
The inability of the male to effect FERTILIZATION of an OVUM after a specified period of unprotected intercourse. Male sterility is permanent infertility.
An assisted fertilization technique consisting of the microinjection of a single viable sperm into an extracted ovum. It is used principally to overcome low sperm count, low sperm motility, inability of sperm to penetrate the egg, or other conditions related to male infertility (INFERTILITY, MALE).
A form of male HYPOGONADISM, characterized by the presence of an extra X CHROMOSOME, small TESTES, seminiferous tubule dysgenesis, elevated levels of GONADOTROPINS, low serum TESTOSTERONE, underdeveloped secondary sex characteristics, and male infertility (INFERTILITY, MALE). Patients tend to have long legs and a slim, tall stature. GYNECOMASTIA is present in many of the patients. The classic form has the karyotype 47,XXY. Several karyotype variants include 48,XXYY; 48,XXXY; 49,XXXXY, and mosaic patterns ( 46,XY/47,XXY; 47,XXY/48,XXXY, etc.).
A medical-surgical specialty concerned with the morphology, physiology, biochemistry, and pathology of reproduction in man and other animals, and on the biological, medical, and veterinary problems of fertility and lactation. It includes ovulation induction, diagnosis of infertility and recurrent pregnancy loss, and assisted reproductive technologies such as embryo transfer, in vitro fertilization, and intrafallopian transfer of zygotes.
