The success of clinical IVF was initially compromised by sub-optimal culture conditions, resulting in impaired embryo development (1–6) and a subsequent loss of viability. However, research during the past 10–15 years has resulted in the development of more physiological and effective culture media capable of maintaining the viability of the developing embryo (7–10). This in turn has resulted in an increase in implantation rates and a decrease in the number of pregnancies lost. Furthermore, more suitable culture conditions produce embryos more able to survive cryopreservation (11). ...
Recent reviews have addressed issues of cigarette smoke
exposure and various facets of reproduction including
delayed time to conception, ovarian effects and premature
menopause, implantation failure, fetal growth restriction
and growth retardation, placental abnormalities, reduced
fecundity, congenital abnormalities, and effects on male
reproduction [32-34]. However, most prior reviews have
not considered smoke's interaction with the oviduct, an
organ vital to reproduction.
Grace period after the expiry of the 10 - year storage limit
W e recommend amending clause 5 of the bill by substituting new
text to repeal and replace section 10 of the Act. W e also recommend
the adoption of the related new purpose clause 4(aa). These amend-
ments would provide a grace period of six months upon the expiry of
the 10 - year storage limit and any extensions to it. The grace period
would lessen the burden of disposal management for fertility clin-
Since its first description by Steptoe and Edward, IVF gained popularity among both
doctors and patients. There is many studies on assisted reproduction and they cover
most of the related technical, laboratory as well as clinical aspects. To write a book on
assisted reproduction nowadays seems very difficult due to a wide plethora of related
papers and well-illustrated books. This small-sized book aims at refinement of some
already known points of practical importance in infertility management particularly
We have previously reported a mouseRnf33⁄Trim60gene that is temporally
expressed in the pre-implantation embryo. TheRnf33structural gene is com-posed of a short noncoding exon 1 and an intronless coding exon 2. In the
present work,Rnf33was shown to be expressed in the mouse testis and in the
testicular cell lines TM3 and TM4.

Surrogacy is an agreement in which a woman becomes pregnant and gives birth to a child for
someone else. Surrogacy can be paid or unpaid, and often involves a legal contract in which the
surrogate gives up parental rights to the child she births. If the surrogate’s own eggs are used
through alternative insemination or IVF, she is known as the “genetic surrogate.” If embryos are
created using another woman’s eggs and implanted in the surrogate, she is known as the
“gestational surrogate” and has no genetic tie to the child. Hiring a surrogate in the US can...
Ectopic pregnancy is defined as a pregnancy in which the implantation of the embryo occurs out- side the uterine cavity, most frequently in one of the two fallopian tubes or, more rarely, in the abdo-minal cavity or the cervix .
