Before immunological pregnancy tests were developed in the 1960s, women relied on urine-based pregnancy tests using animals, ranging from mice to frogs. [1] [2] Advancements in medical technology have enabled women to accurately check their pregnancy status by using 'pee-on-a-stick' pregnancy test kits at home. Before these accessible and ...
Before Crane's invention, women would have to go to a doctor and have their urine tested in a lab to determine if they were pregnant. As a result, women would have to wait weeks for results. In the 1960s, when Crane's idea first came to be, a pregnancy test was processed in a lab by monitoring levels of a hormone called human chorionic ...
A later article, independently authored, granted Hogben credit for the principle of using Xenopus to determine gonadotropin levels in a pregnant woman's urine, but not for its usage as a functional pregnancy test. [40] Hormonal pregnancy tests such as Primodos and Duogynon were used in the 1960s and 1970s in the UK and Germany. These tests ...

While many people assumed that the injected rabbit would die only if the woman was pregnant, in fact all rabbits used for the ...
Louise Joy Brown (born 25 July 1978) is an English woman noted as the first human born following conception by in vitro fertilisation (IVF). Her birth, following a procedure pioneered in Britain, has been lauded among "the most remarkable medical breakthroughs of the 20th century".
After more than 100 attempts a pregnancy was obtained which was carried to term. Now the technique, as used by Steptoe and others, is so successful that almost a third of women accepted for treatment have healthy infants. His achievement is particularly remarkable as it was obtained in a district hospital with only local backing. [11]
From ancient history to the modern day, the clitoris has been discredited, dismissed and deleted -- and women's pleasure has often been left out of the conversation entirely. Now, an underground art movement led by artist Sophia Wallace is emerging across the globe to challenge the lies, question the myths and rewrite the rules around sex and the female body.
Pregnancy tests are not accurate until 1–2 weeks after ovulation. Knowing an estimated date of ovulation can prevent a woman from getting false negative results due to testing too early. Also, 18 consecutive days of elevated temperatures means a woman is almost certainly pregnant. [61]
