7 Famous People With Kallmann Syndrome or Anosmia

Kallmann syndrome (KS) is a condition that is characterized by absent or delayed puberty and an impaired sense of smell.

Males with the syndrome may have signs of the condition at birth, like – a smaller than average penis or undescended testes.

In patients with KS, their body does not make sufficient gonadotrophin-releasing hormone.

The role of this hormone is to stimulate the ovaries in females and the testicles in males to produce sex hormones.

KS is the most common form of isolated hypogonadotropic hypogonadism.


The syndrome usually has the following clinical manifestations:

  • severe malformation or congenital absence of one or both kidneys;
  • presence of a small penis in males;
  • excessive bone growth;
  • failure of testicular development in males;
  • bimanual synkinesis;
  • erectile dysfunction or decreased libido in males;
  • dental defects;
  • the absence of a menstrual period in females;
  • abnormal ocular movements;
  • incomplete development of secondary sexual characteristics in both genders;
  • craniofacial anomalies;
  • infertility;
  • decreased vaginal lubrication in females;
  • osteoporosis;
  • color blindness;
  • a total absence of the sense of smell (anosmia);
  • impairment in sensory or motor function of the lower extremities;
  • partial impairment of the sense of smell (hyposmia);
  • epilepsy;
  • fatigue;
  • sensorineural hearing loss;
  • shortness of breath;
  • loss of muscle tone;
  • palpitations;
  • fainting;
  • bluish discoloration of the skin called cyanosis.


The underlying cause of KS is the breakdown of the communication between the pituitary glands and the hypothalamus.

Mutations in several genes are linked with KS. These genes include – CHD7, ANOS1, FGF8, PROK2, FGFR1, or PROKR2.


The diagnosis of KS may be suspected with evidence of incomplete sexual maturity and evidence of lack of sexual maturation.

Note – due to lack of sexual development, most cases are diagnosed at the time of puberty.

Hormone replacement is given to both girls and boys. Girls need female sex hormones progesterone and estrogen. Boys need testosterone, a hormone that lets them grow and develop during puberty.


It is the complete or partial loss of the sense of smell. This loss may be permanent or temporary.

Note – in KS, the sense of smell is either completely absent (anosmia) or diminished (hyposmia).

Here Is A List Of 7 Famous People With Kallmann Syndrome or Anosmia:

#1 Lawrence Koomson

He is a doctor living and working in London who has KS. Koomson has never had bodily hair, has never had acne, and has never had an erection.

According to his healthcare professional, Koomson had the testosterone levels of a 1-year-old and a 4-centimeter penis before he started treatment.

During an interview, Lawrence Koomson said:

“I feel an outsider, different to everyone else.

Koomson went on to say:

”People take going through puberty for granted; it’s just something that happens. For me, it has just never happened.”

However, when Dr. Bouloux proposed a treatment to boost his testosterone levels in April 2005, this changed, and Lawrence was about to experience puberty.

The treatment consisted of 6 transdermal implants in the buttocks which released 200mg of testosterone.

After six months of treatment, Koomson has started to feel sexual attraction, to have erections, and to explore dating possibilities.

#2 William Wordsworth
