Anti-Müllerian Hormone as a Marker for Castration Status and Fertility in Bulls and Oxen. [PDF]
Reprod Domest AnimABSTRACT Anti‐Müllerian hormone (AMH) has been established as an indicator of castration status and fertility in several species. However, its applicability in postpubertal bulls and oxen has not yet been thoroughly investigated. This study examined 73 bulls aged between 12 and 107 months and 37 oxen older than 12 months.

Neonatal exposure to xenoestrogens impairs the ovarian response to gonadotropin treatment in lambs [PDF]
, 2015 Bisphenol A (BPA) and diethylstilbestrol (DES) are xenoestrogens which have been associated with altered effects on reproduction. We hypothesized that neonatal xenoestrogen exposure affects the ovarian functionality in lambs.

Superovulation in mice in relation to their age [PDF]
Veterinary Quarterly, 1982 Superovulation in mice is most likely to be successful if they are treated at the age of 20-32 days. Both the number of ovulations and the quality of the embryos are significantly better in comparison with superovulated older mice (32-60 days). In this investigation the production of normally developed embryos in young mice of 20-32 days old was 28.7 ...

Studies on Superovulation in the Rabbit with Special Reference to Repeated Superovulation
Nihon Chikusan Gakkaiho, 1978 家兎において多数の卵子あるいは受精卵を得るための過排卵ならびに反復過排卵誘起法について検討し,つぎの成績が得られた.1) FSHとLHないしFSHとHCGの組み合わせにより家兎に過排卵処置を行なったところ,1頭当り平均30個以上の受精卵が得られた.2) 反復して過排卵処置を行なう場合,1回目の採卵時前後にエストロジェンを投与しておくと,2回目の排卵数の低下がある程度防がれた.3) 回収された卵子のうち受精卵の子宮への移行は交配後67時間目で初めてみられたのに対し,未受精卵の場合は46時間目ですでに子宮より検出された.4) 過排卵処置により得られた受精卵を排卵時期を同期化した偽妊娠家兎に移植し正常子が分娩された.

SUPEROVULATION AND SUPERPREGNANCY IN THE GOLDEN HAMSTER* [PDF]
Development, Growth and Differentiation, 1980 Pregnant mare serum gonadotropin (PMSG) treatment given in the morning or afternoon on any day of the four-day estrous cycle and human chorionic gonado tropin (HCG) given two days later successfully induced superovulation in the golden hamster. The minimum interval between PMSG and HCG necessary to obtain consistent superovulation was approximately 44 ...

Does supplemental LH changes rate and time to ovulation and embryo yield in Santa Ines ewes treated for superovulation with FSH plus eCG?. [PDF]
, 2015 : The objective was to evaluate if supplemental LH given at the end of FSH treatment would synchronize the time of ovulation and increase the ovulation rate and embryo yield in Santa Ines ewes.
