Aktivasi Oosit Menggunakan Strontium Klorida setelah Injeksi dengan Spermatozoa Domba Hasil Pengeringbekuan (OOCYTE ACTIVATION USING STRONTIUM CHLORIDE FOLLOWING INJECTION OF FREEZE-DRIED RAM SPERMATOZOA)

Jurnal Veteriner, 2013
One of the factors that inhibit the formation of male pronuclei following injection of freeze-dried ramspermatozoa was the absence of artificial activation during oocyte incubation after the injection.

Artificial oocyte activation: evidence for clinical readiness [PDF]

, 2016
Artificial oocyte activation using Ca2+ionophores or similar compounds is a widely applied technique in IVF laboratories. This is all the more interesting as most of the agents aiming for intracellular Ca2+ increase do not result in physiological Ca2 ...

Pronuclear formation by ICSI using chemically activated ovine oocytes and zona pellucida bound sperm

Journal of Animal Science and Biotechnology, 2016
Background In order to improve ICSI, appropiate sperm selection and oocyte activation is necessary. The objective of the present study was to determine the efficiency of fertilization using ICSI with chemically activated ovine oocytes and sperm selected ...

Oocyte activation, phospholipase C zeta and human infertility.

, 2010
BACKGROUND: Mammalian oocytes are activated by intracellular calcium (Ca(2+)) oscillations following gamete fusion. Recent evidence implicates a sperm-specific phospholipase C zeta, PLCζ, which is introduced into the oocyte following membrane fusion, as ...

Hormone therapy (HT) in women with premature ovarian insufficiency or early menopause: Time to think of a new paradigm for healthy aging. A joint FIGO and IMS position paper

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Premature ovarian insufficiency (POI) and early menopause (EM) affect millions of women worldwide. Compared with normal menopause, they confer a longer duration of estrogen deficiency and are associated not only with a shorter lifespan, but with a reduced healthspan, owing to an increased risk of cardiovascular, skeletal, cognitive and ...

Oocyte Donation [PDF]

, 2017
The use of donor oocytes has expanded the scope of assisted reproductive technology (ART) for women with poor oocyte quantity and quality. In vitro fertilisation with oocyte donation (IVF-OD) is considered to give better implantation, pregnancy, and ...
