Welcome to the 6th issue of Fertility Research Review
In this issue we review several studies investigating sperm quality. Many men are unaware that the use of finasteride, a common treatment for baldness, reduces sperm counts. Fortunately for couples desiring fertility, sperm counts were shown to increase on cessation of finasteride treatment. Couples may also need to reconsider use of lubricants as some are shown to have detrimental effects on sperm motility in an in vitro study. Using IMSI for sperm selection increased pregnancy rates in older women in a prospective randomised study. Other studies reviewed this issue show increased pregnancy rates with ICSI preceded by endometrial injury and in egg donor recipients with replete vitamin D levels. The mechanisms for these influential factors are not yet understood.
We hope you enjoy our selection for this edition and your comments and feedback are welcome.

Fertility treatments and multiple births in the United States
Authors: Kulkarni AD, et al.
Summary: The increased use of fertility treatments in the United States has been associated with a
substantial rise in the rate of multiple births. The proportion of multiple births that were attributable to
IVF and non-IVF fertility treatments from 1997 through 2011 was estimated and compared with rates of multiple births after natural conception. A total of 36% of twin births and 77% of triplet and higher-order births resulted from conception assisted by fertility treatments. The observed incidence of twin births increased by a factor of 1.9 from 1971 to 2009. The incidence of triplet and higher-order births increased by a factor of 6.7 from 1971 to 1998, but decreased by 29% from 1998 to 2011 when clinical practice guidelines for IVF had been developed. During this time there was a 70% reduction in the transfer of three or more embryos for IVF (p<0.001).
Comment: Multiple pregnancies have been the dirge of the fertility world. This report estimates that
more than a third of all twins occur as a result of fertility treatments and more than three quarters of
all triplets. These multiple pregnancies are almost all avoidable with the adoption of a single embryo
