However, as sperm numbers / ejaculates were hitherto mostly found to be increased rather than decreased under high densities and because mating couples were removed from the mating cages immediately after the initiation of mating in our study, social influences are unlikely to be the reason for re...
The number of intromissions required to elicit ejaculation actually decreases for a few days after castration. Therefore, one function of T may be to increase the number of intromissions preceding ejaculation, which would increase the number of sperm in the ejaculate, facilitate sperm transport, ...
Semen characteristics before and during the mating period were recorded in three experiments in groups of rams joined with different numbers of ewes. In comparison with pre-joining levels, volume, density, and therefore number of sperm per ejaculate, had fallen to low levels in ejaculates collected...
AFC = antral follicle count; AMH = anti-Müllerian hormone; ICSI = intracytoplasmic sperm injection; PPOS = progestin-primed ovarian stimulation. This study was approved by the Medical Ethics Committee of the First Affiliated Hospital of Xinjiang Medical University (approval number:...
Because in the Berberidaceae fruit forms resembling a “semi-siliqua” are produced, they are also controversial. A siliqua is typically furnished with two placental regions joined by a septum and dehiscing through detachment of two sterile valves. Modified forms lack a septum and have only one ...
It is worth mentioning at this point that, overall, prostate biopsy is usually well tolerated and the most frequently occurring complications include cases of hematuria, hematospermia and hematochezia. Infectious complications occur less often but seem to have increased in the last decades [30]. ...

Each patient produced two samples: the first on the day of the LH surge, the second a day later. Male factor patients were classified as follows: oligozoospermic (OZ; count <20 mill/ml), asthenozoospermic (AZ; motility <40%), and oligoasthenozoospermic (OAZ), as determined by ...
Use of intracytoplasmic sperm injection was associated with lowered delivery rate. Conclusion(s) No more than three or four embryos should be transferred in 38- and 39-year-olds, respectively, whereas up to five embryos could be transferred in ≥40-year-olds. Numbers of embryos to transfer ...
