Do you know that
in both
fertile and infertile women the fertility potential of oocytes from the right
ovary surpasses that of the left ovary
Do you believe that
in a given cycle -Right-sided ovulation favours pregnancy
more than left-sided ovulation.

Right-sided ovulation
favours pregnancy more than left-sided ovulation.

Abstract
The aim of this study was to evaluate whether frequency of
ovulation and fertility potential of oocytes from the two ovaries differed in
regularly menstruating women (1057 cycles of 856 fertile women and 1033 cycles
of 258 infertile women).
For both fertile and infertile women Point 1: ovulation from the right ovary
occurred more often than from the left ovary (55 versus 45%; P: < 0.005).
Point 2: In infertile women follicular phase length was
similar for right- and left-sided ovulation. Point 3 : However,
infertile women treated with intrauterine insemination (IUI) or in-vitro fertilization (IVF) showed a
pregnancy rate in connection with right-sided ovulation (13%) which was higher
than that of left-sided (9%).
The ratio of pregnancies deriving from the right ovary per total
number of pregnancies was similar in infertile and fertile women (64.6%, 73/113
and 63.4%, 361/569 respectively).
Point 4 : The ratio of pregnancies from right-sided
ovulation (approximately 64%) per total number of pregnancies was higher than
that of right-sided ovulation (approximately 55%) during non-pregnant cycles
(P: < 0.0001).
Point 5: The
implantation rate
in right-sided ovulation seemed to be higher than in left-sided one, since IVF
data showed a lower frequency (P: = 0.03) of pre-embryo formation from
right-sided ovulation than left-sided.
Point
6: Mid-luteal serum oestradiol and testosterone were higher (P:
< 0.05) in right-sided ovulation than left-sided..
