Anti‐Müllerian hormone as a promising novel biomarker for litter size in Romanov sheep
Reproduction in Domestic Animals, Volume 59, Issue 8, August 2024.Abstract Anti‐Müllerian hormone (AMH) is a hormone produced by growing preantral and antral follicles of the ovary. AMH is accepted as an important biomarker for fertility and superovulation parameters in livestock species. This study aimed to evaluate changes in serum AMH level in the oestrous cycle, repeatability of AMH, the effect of age on serum ...

, 2006 A polymerase chain reaction (PCR) assay which detects a sex-based polymorphism in the bovine amelogenin locus was modified and compared to conventional cytogenetic analysis for diagnosis of freemartinism (XX/XY chimerism) in cattle.

Characteristics of unilateral and bilateral bovine twin foetuses
Reproduction in Domestic Animals, Volume 59, Issue 7, July 2024.Abstract Twin pregnancy in cattle is undesirable for a number of reasons, including a higher abortion risk compared to pregnancies with a single foetus. Yet, the abortion risk is significantly influenced by the intrauterine location of the foetuses, that is, the abortion risk is several times higher if they are implanted in the same uterine horn ...

Anti‐Müllerian hormone: A novel biomarker for detecting bovine freemartinism
Reproduction in Domestic Animals, Volume 59, Issue 2, February 2024.Abstract The anti‐Müllerian hormone (AMH) indicates ovarian reserve in cattle, maintaining a consistent trajectory post‐puberty. In heterosexual pregnancies, the development of the Müllerian duct in female foetuses is inhibited, resulting in an anticipated minimal or absent ovarian reserve capacity.

Potential case of pseudo-hermaphroditism in Elk (Cervus canadensis) in Alberta, Canada
, 2020 Cases of true and pseudo-hermaphroditism, in which animals possess both ovaries and testes or have a single chromosomal and gonadal sex but secondary features of the other sex, have been documented in several cervids, including Odocoileus (deer) and ...

Dizygotic monochorionic canine foetuses with blood chimaerism and suspected freemartinism
, 2017 Two full-term canine fetuses were found to share a placenta during Caesarean section. The fetuses were of discordant gender, with apparently normal male and female external genitalia.

Leukochimerism genotyping data
, 2023 <p> </p> <p><span>Twinning in cattle is infrequent, and also undesired. It can result in increased occurrence of abortion and dystocia, reduced calf survival, and a high likelihood of freemartinism in mixed-sex twins.

Possibility of freemartinism in roe deer [PDF]
Acta Theriologica, 1984 Cytogenetic analysis was made in female roe deer, Capreolus capreolus (Linnaeus, 1758), belonging to members of heterosexual triplets. Lymphocytic chimerism was not discovered, the cariotype being defined as 70,XX. The result obtained justifies the assumption that in cases of twin or multiple pregnancy of unlike sexes in the roe deer there is no ...

Diagnosis of Freemartinism Syndrome by Polymerase Chain Reaction (PCR) in Cattle
, 2011 Freemartinism syndrome is a case of sterility in female twin off spring when twin pregnancy exists with the different sexes, and caused by involvement of male twin's blood stem cell factor and anti-Mullerian hormone into female twin.
